Greater Paris Metropolis

Biomimicry, circular economy, urban greening, set the tone for the future Greater Paris Metropolis.

The results of the competition "Let's Invent the Metropolis" launched in spring 2016, unveiled 51 winners (out of 420 applications) on Wednesday 18 October at the Pavillon Baltard in Nogent-sur-Marne. Greater Paris is thus seeking to develop new centres of attraction, based on in-depth consideration of new uses, the circular economy, resilience and sustainable mobility, with a flexible and modular approach to housing. High-tech urban agriculture, biomimicry and vegetalization are among the many architectural and technological innovations to encourage the return of nature and biodiversity to the city. Overview of the winners.
Quartiers de gare, heritage sites, city centre, urban wasteland, ... the diversity of sites proposed by Let's invent the Metropolis of Greater ParisThe 54 plots of land enabled the candidates to deploy a wide range of technical know-how and architectural innovations in order to come up with tailor-made projects that reflect a great understanding of the site. All of the sites in the consultation process are intended to become emblematic sites, signals revealing the great capacity for innovation of the Greater Paris Metropolis and vectors for integrating new territories with the aim of creating a new metropolitan identity.
Let's Invent the Metropolis has been able to attract, alongside promising young French agencies (Encore Heureux, Muoto, Maud Caubet Architects, Des Clics et des Calques), the big names in international architecture, some of whom have built little in France. Big names such as Sou Fujimoto, Rogers Stirk Habour & Partners, Dominique Perrault, OMA, Shigeru Ban, Kengo Kuma, Stefano Boeri Architetti, Snøhetta, MVRDV and Studio Gang have proposed projects of very high urban and architectural quality. The presence of heritage sites such as La Maison du Peuple in Clichy-la-Garenne and industrial sites such as the Babcock site in La Courneuve promise remarkable architectural achievements.

Key figures  
Ernst and Young carried out a study on the economic and territorial impact of the investment projects that won the call for projects "Inventing the Greater Paris Metropolis".
- The 54 winning projects are expected to generate a total investment of 7.2 billion euros, divided between construction work (62%), land acquisition (18%) and ancillary expenditure (2O%).
- They represent a land area of 165 ha which should accommodate 2.1 million square meters divided between 815,000,000 m2 of housing (14,300 new housing units), 867,000,000 m2 of economic activities (including 651,000,000 m2 of tertiary surfaces), 175,000,000 m2 of public and private facilities and services, 86,000,000 m2 of hotel facilities (2,800 rooms), 166,000,000 m2 of local shops and restaurants, etc.
- The study and work phase could lead to the creation of nearly 230 jobs per year in study activities and 7000 jobs per year in construction during the work phase, i.e. a theoretical total of 65 500 jobs over a projected seven-year period.

Architectural audacity and constructive innovations

>> Emblematic site of the consultation, the House of the People in Clichy-la-GarenneThis building, classified as a Historic Monument, is a jewel of 1930s architecture. A true "mechanical jewel", this building is emblematic of the first ingenious design techniques allowing flexible uses: market, festival hall, cinema room.
People's House Project
Its restoration by the GROUPEMENT DUVAL is the subject of a demanding and singular approach, giving way to a sensual and powerful architecture, signed RUDY RICIOTTI and IBA+HOLZWEG.
Made of fibre-reinforced concrete and glass, an R+30 tower will be placed in equilibrium next to the Maison du Peuple, the result of a constructive feat imagined by LAMOUREUX & RICCIOTTI INGENIERIE, since its exoskeleton carrying the whole building will be cast on site in a gigantic sarcophagus. It is also an economical architecture in 16 materials (eco-design followed by MILIEU STUDIO and EKOPOLIS) paying tribute to French construction know-how as Jean Prouvé did in his time. Balanced on the Maison du Peuple so as not to impact the floor of the public space, the tower will dialogue like a sentinel with the Cité judiciaire des Batignolles.
>> Artistic and poetic architecture in timber construction of the Argenteuil Littoral project opens up to the Seine. Through their innovative proposals, the ATELIER DU MIDI and BRICQUEVILLE reveal to the public an exceptional site, a balcony overlooking Paris, which already inspired great names of the Impressionists such as Monet, Sisley, Caillebotte and many others.
Model of L'atelier du Midi et Bricqueville of the Argenteuil littoral project

Flagship building of the project, operated by WALK, the emblematic hotel with its views overlooking Paris and radiating out over the Val d'Oise first of all creates a deliberate break, symbolizing the gateway to the Metropolis. The project then continues with a beautiful balance between buildings and open spaces, ensuring a vegetated breathing space orchestrated by AM ENVIRONNEMENT and an integral part of the site's identity.
On the banks of the Seine, Argenteuil Littoral offers a dreamlike opening to its inhabitants as well as to tourists via the architectural and artistic gesture of an unfinished footbridge, the culmination of a cultural walk proposing a staging by contemporary artists such as KINYA MARUYAMA, in a process of co-construction with the inhabitants coordinated by ANAGRAPHIS and TRAIT CLAIR.
>> Developed in a very heterogeneous architectural, urban and landscape context, the project of the LINKCITY Genopole in Evry integrates a smoothly integrated campus, in a cocoon logic open to the city, modular, flexible and scalable. As a signal building, a corner building protects the site from the noise and visual nuisance of the RN7, while the vegetation enters the heart of the campus, punctuated by visual porosities with the city.
In addition to its perfect registration on the site, the architecture and organization of the project were designed by the firms CHAIX & MOREL and BIDARD & RAISSI in direct relation with the image and stakes of the Genopole®.
The constructive innovation of the project thus lies in its concept of extreme modularity and its very strong capacity for evolution and reversibility. The project will be built in several phases and will operate on the principle of cores that can be modulated at will according to the evolution of needs and uses: sometimes offices, sometimes laboratories or clean rooms. Flexible and scalable, the second building complex on the site will be deployed in phase 2 and will be expandable on the interior of the campus. While the fragmentation of the volumes confers a dynamic image of the site, a homogenous façade treatment and a strong architectural identity govern all the modules: concrete, aluminium and glass interact for a contemporary, well-kept and durable façade.
>> The Balcon sur Paris project on the Villiers-sur Marne site offers an exceptional architecture. By its construction technique signed EQUILIBRIUM, Its rate of vegetalisation (the landscape designers JAMES CORNER FIELD OPERATIONS and the ATELIER PAUL ARENE have managed to green more than 50% of roofs and courtyards) and its responsible approach, the Belvedere district thus pays a fine tribute to the site's natural heritage.
Europe's first high-rise district in timber construction, Balcon sur Paris is the culmination of the joint work of talented and renowned architects with complementary architectural styles, specialising in high timber structures such as KENGO KUMA & ASSOCIATES, STEFANO BOERI ARCHITETTI, XTU, MGA, OXO, MICHAEL GREEN ARCHITECTURE and KOZ Architects.
Project Un Balcon sur Paris, near the Marne Europe station in Villiers-sur-Marne designed by Kengo Kuma  
The project is proving to be a real showcase for innovation in terms of mobility thanks to the collaboration of players such as TRANSITEC, TRANSDEV and ZENPARK, energy with SINTEO, biodiversity (the project notably integrates the LPO), uses and programme, a pilot district that will be a reference.

Circular economy and the fight against climate change

Climate change due to the footprint of our lifestyles is well documented. 70% of global greenhouse gas emissions are energy-related, 23% of emissions are from the transport sector, while buildings account for 19% of emissions and 32% of global energy consumption.
The Greater Paris Metropolis concentrates many challenges (food, mobility, production, energy...) and is therefore a wonderful field for accelerating and experimenting with solutions. Thanks to the Grand Paris Express, all the inhabitants of Greater Paris will be less than 2 km from a train station in 2030, which offers a major lever for reducing emissions linked to automobile traffic.
At the forefront in this field, the Greater Paris Metropolis has made climate action one of its top priorities and is voluntarily implementing a metropolitan climate-air-energy plan (PCAEM) with precise objectives and concrete actions.
Placed at the heart of the challenges of Inventons la Métropole du Grand Paris, the climate and the circular economy have thus been the subject of innovative strategies on the part of the candidates. Among the most noteworthy projects, Lab 21 on the Romainville site, the Triango project on the Triangle de Gonesse, Le Temps sur Mesure in Bagneux, Les Grands Lilas on the Romainville Fort and the Antonypôle project.
>> "Energy Transition and Sustainable Growth Laboratory", the LAB21 proposes for the site of the ZAC de L'Horloge in Romainville, a project aiming at zero carbon, zero waste, zero fossil and fissile energy while promoting the return of nature and biodiversity to the city. Also innovative on a social level, the initiative of the promoter ALSEI, theFRANC ARCHITECTE AGENCY and HORTICULTURE & GARDENS aims to generate a real dynamic of emulation of the environmental action between the different actors of the project.
Project LAB21
Vegetalization of the site and the building, use of bio-sourced materials and respectful and modular construction techniques, compensation approach, proposal of collaborative work space, hosting of participative fablabs dedicated to ecodesign and sustainable food, implementation of a users' charter and incentive schemes favouring soft mobility and short circuits thanks to the integration of urban and eco-productive agriculture operated by LES SOURCIERS, recalling the agricultural and market gardening past of Romainville. The LAB21 accelerates the transition towards more sustainable lifestyles.
>> On Gonesse's triangleBOPRO SUSTAINABLE INVESTMENTS and the architectural and urban planning firms RAU, SEARCH, PHILEAS, KARRES+BRANDS place the circular economy at the heart of the project. Triango and are committed to developing a mixed programme including a demonstrative business district exclusively dedicated to the circular economy as well as 10,000 m² of innovative urban agriculture structures with BIGH, LATERAL THINKING FACTORY CONSULTING and URBAN CROP SOLUTIONS.
The design, development and construction of the project will be carried out in accordance with the principles of circular economy thanks to the expertise of TURNTOO. The entire life cycle of the buildings is designed by ITF to reduce their environmental footprint. The materials used for the construction of its positive energy buildings will be chosen according to two major criteria: their energy performance and their ability to be reused in order to produce buildings that are both sustainable and mutable. The facilities and services offered by EVERGREEN will promote the development of sustainable mobility with, in particular, scooter parks by KNOT; the provision of classic and electric bicycles by GREEN ON and autonomous electric shuttles by WATTMOBILE; or a car-sharing service with WAYZUP.
 >> Bioclimatic project, tailor-made time in Bagneux places biodiversity, low-carbon objectives and the circular economy at the heart of its design and operation. The program includes a roof-top urban agriculture system developed with LIVING ROOFS, including greenhouses, hydroponics and compost, as well as slab gardens in the open ground providing the ideal terrain for permaculture and promoting short circuits. Frugal, the project also includes a rainwater harvesting system and the reuse of demolition materials. Developed in collaboration with PARI ARCHITECTURE ECOLOGIE, the programme's buildings offer high-performance bioclimatic housing, as well as workshops to raise awareness among residents to optimise energy savings. They integrate natural ventilation and an innovative system of inertia of phase change materials.
>> Business Incubator of the collaborative and circular economy, Les Grands Lilas presents a strong ambition on the reduction of the carbon impact of the building during its construction and its life cycle on the site of the Fort dit de Romainville in Les Lilas.
Aiming for the highest level of excellence of the BBCA label, the CIBEX promoter's project will operate on solar thermal and geothermal energy, will use bio-sourced materials for the renovations and constructions planned on the site, and requires a high degree of reversibility of the buildings constructed. In its operation, the project will encourage the reuse of materials, either on the site itself or through artistic activities thanks to RESERVE DES ARTS. Conceived by the urban planner SHAHINDA LANE, the architecture studios GARE DU NORD ARCHITECTURE, STUDIO MUOTO, MOOTZ & PELE ARCHITECTES, the association PEEPING TOM for territorial anchoring and the land art artist JEAN-PAUL GANEM, the Grands Lilas project finally favours soft mobility by excluding access to the site for cars.
 >> Ambitious demonstrator of the Swiss concept of the "2000W company", the LINKCITY Antonypole project, designed by AREP, LAISNE ROUSSEL, CLEMENT BLANCHET and COLOCO, aims to reduce energy consumption by a factor of three.
The programme operates on the basis of production and self-consumption of renewable energy, even offering the possibility of storing surplus energy via TESLA. It thus offers a very low carbon energy and thermal mix. In addition to this, there is a programme to raise awareness among the inhabitants of the eco-neighbourhood, carried out with the WWF, the setting up of short food supply circuits thanks to partnerships with local associations and the NU! zero-waste retailer; or an incentive for more sustainable mobility thanks to a self-service offer of MOBER electric scooters, a self-sharing bicycle system operated by CLEM and the setting up of electric recharging stations on the site.

Culture and creation as levers of innovation

Culture and creativity are at the heart of the development of Greater Paris, as demonstrated by the cultural and artistic project led by the Société du Grand Paris or the key role of the creative industries in its international influence.
At a time when innovation processes are opening up, what is the impact of culture and its capacity to drive economic and social innovation? What is its role in urban projects?
Convinced of the immense potential of art and culture for the integration and influence of territories, the Metropolis of Greater Paris paid particular attention to the place accorded to them in the proposed projects. Among the remarkable projects in terms of creative and cultural innovation are the Maison du Peuple, Les Grands Lilas, STO Art & Design Center, La Fabriques des Cultures, Les Lumières Pleyel.
 >> Designed in 1935 by emblematic avant-garde architects and engineers, the Maison du Peuple was a particularly innovative building at the time.
Listed as a Historic Monument since 1983, it operates, among other things, mobile floor and sunroof systems that allow an incredibly up-to-date flexibility of use. The challenge of its transformation was thus to breathe new life into the innovation permeating this site, now partially disused, by anchoring the Maison du Peuple in the 21st century. A successful gamble for the GROUPEMENT DUVAL thanks to its modular project mixing citizen participation and ambitious cultural programming, around a space for the presentation of the permanent collections of the CENTRE NATIONAL D'ART ET DE CULTURE-GEORGES POMPIDOU, and cultural spaces designed and animated by SCINTILLO, with the involvement of ARTY FARTY for the cultural editorial.
>> Les Grands Lilas has proposed, on the site of the Fort dit de Romainville aux LilasThis is a rehabilitation project balanced between the protection of this metropolitan landmark and future-oriented cultural appropriation. A Vauban-type fort that served as an internment camp for resistance fighters in transit to the Nazi concentration camps during the Second World War, the Fort known as Romainville will host a project built around the main threads of culture and agriculture. A place for the production and dissemination of cultural works, an incubator for social and solidarity economy businesses, a leisure and professional integration centre, the site will remain a green setting thanks to an artistic agri-urban park open to the public. Numerous highly complementary players will carry out this project: MAINS D'ŒUVRES will run a third location in the casemates while RÉSERVE DES ARTS will ensure the reuse of artistic materials by the artists occupying the site. UNITED KITCHENS will propose culinary coworking. The SOLAR HOTEL will be a unique place of training dedicated to responsible hotel management. SIMPLON.CO will take care of digital training.
>> On the Babcock industrial wasteland in La Courneuve, La Fabrique des Cultures brings together local institutions and organizations of Greater Paris through the creation of an Augmented Image Cluster (including COTE COURT, CINEMA 93, PERIPHERIE ET CITIENNETE JEUNESSE, L'ABOMINABLE, ETOILE CINEMA or ENCORE L'ECRAN) and the genesis of the Grand Paris Schola (bringing together ENS ARTS DECORATIFS, ENSCI, BEAUX-ARTS DE PARIS AND CERGY).
Taking culture and creation as its foundation, the project will allow the emergence of a district that is unique to date through a co-programming involving the public, local economic actors and inhabitants, in addition to the opening of real behind-the-scenes spaces for cultural production.
A marker of local industrial history in an urban context in the midst of redevelopment, the former Babcock factory, with its 4 ha of industrial wasteland, its architecture and its remarkable volumes, offered the ideal playground for this project of unprecedented scale, led by the architect DOMINIQUE PERRAULT, ENCORE HEUREUX (prefiguration of the site) and APRES LA PLUIEUX (landscaper) with the support of QUAI 36 for the cultural centre and the INTENCITY incubator.
>> At the crossroads of all dynamics, identified as the spearhead of the Territory of Culture and CreationThe Pleyel Lights in St Denisis destined to become a new hub of the Greater Paris Metropolis. From 2023, it will house the Saint-Denis-Pleyel station - a hub of connections between lines 14, 15, 16 and 17 of the Grand Paris Express, line 13 of the Paris metro and lines D and H of the Transilien network - and will offer no less than 4,900 m² of art and culture.
The Pleyel lights, in Saint-Denis

To date, permanent and semi-permanent artistic commissions as well as a cultural programme highlighting and staging the various buildings on the site are planned, notably through light creations. The artistic and cultural direction of the site will be led by MANIFESTO, creator of artistic and cultural projects, and the 104.
>> Case dedicated to culture, art and design, the STO Art and Design Center project on the St Ouen Flea Market places culture and a collaborative approach at the forefront of its innovation strategy. Transforming an urban crossroads into a place of meeting, conviviality and creative synergies, it integrates local and metropolitan actors for a renewal of the modalities of artistic creation.
The project thus proposes, upstream of the construction site, the creation of a collective and participative work with the inhabitants of the neighbouring towers, in collaboration with the students of the BEAUX-ARTS and the local association JOLI MAI, under the coordination of the cultural operator MANIFESTO. The programme also proposes creative and convivial activities aimed at encouraging the different audiences and actors of the project (JOLI MAI, ANTICAFE, OFFICE DU TOURISME DE PLAINE COMMUNE, ECOLE NATIONALE SUPERIEURE DES BEAUX-ARTS, CARPENTERS WORKSHOP GALLERY, ...) to take ownership of the site throughout its genesis and operation.

Living better

The rate of housing construction in the Greater Paris area is at a level not seen in 40 years. This effort, unique in Europe, responds to the housing needs of its inhabitants and the Greater Paris Metropolitan Area intends to play an essential role in the articulation of housing policies, with the development of a Metropolitan Housing and Accommodation Plan.
Modular and flexible housing, use of data and connection of buildings, reduction of the carbon footprint of our homes, alternative housing, collaborative functioning, quality of life, mix, longevity and evolution of buildings... many are the avenues of experimentation to live better and differently. A priority issue for the Greater Paris Metropolis, the question of innovation by and for housing was crucial to the call for projects.
Numerous projects thus offer innovative and reproducible solutions on the scale of Greater Paris. Agile and modular programs
>> Located in Clichy-sous-Bois, on a very constrained site, the Un Belvédère Métropolitain project has been able to develop an inventive model offering agile housing, services and facilities. The project integrates from its conception, the notion of evolutivity and participative approach, in the service of residential quality and uses.
Conceived by the architecture agency TVK, the project of the developer NEXITY FEREAL and the lessor EFIDIS meets the immediate needs of the inhabitants of Clichois in a frugal and low tech approach, integrates actions of sensitization, led by VILLE OUVERTE, for a control of the carbon balance and the management charges of the co-ownerships; without taking the risk to freeze the typology of the program. This scalability is reflected in a system of housing that works in pairs that can be disconnected and reconnected, the adaptation of the number of parking spaces or the reversibility of the feet of buildings that can change from a local service offer to housing if it no longer meets the needs of the inhabitants.
>> Also very agile, Hospitality A signal in the City proposes, in the Kremlin-Bicêtre, a housing program that evolves with lifestyles. In addition to the proposal for apartments delivered rough and arranged using removable partitions to adapt to a family's lifecycle, the project led by Altarea Cogedim uses the concept of "colonisable" terraces, a legal innovation that allows for the extension of buildings with a 10 to 20m² frame on the terraces simply by means of a Preliminary Declaration of Works from the purchasers.
The Hosipitality Project
In addition to the vast private terraced gardens, the project proposes common areas with cultivated roofs, as well as a third location combining restoration and new cultural practices. Energy activation at the heart of the project
>> Positive energy balance program, the Ôm project in Issy-les-Moulineaux pays constant attention to the well-being of the future inhabitants. As a tribute to the creativity and modernity of the city, a precursor in the application of the principles of the Feng Shui philosophy in a swimming pool and one of its schools, ICADE, ARCHITECTURE STUDIO and LAND'ART are achieving a first by applying these age-old principles in the construction sector, right from the design stage of the project.
Aimed at bringing prosperity, well-being and harmony to homes, Feng Shui and its philosophy have been taken into account and integrated into each phase of creation, right down to the name Ôm, symbolizing the source of the universe. The project is thus aiming to obtain WELL certification.
Innovation through diversity:
>> The Mix'It project, led by BOUYGUES IMMOBILIER, EFIDIS and INTENCITY in the Plaine Ouest district of Noisy-le-Sec, ensures mixed use by offering workshops-accommodation (30 m² workshop / 30 m² accommodation). Close to the operation of the artist's studio, this innovative type of housing is aimed in this project at VSE/SME entrepreneurs. This hybrid solution aims both to diversify the housing supply and to guarantee a mix of uses, while maintaining existing economic activities. This project is based on the expertise of VIVALIB and POP UP IMMO.
>> PICHET GROUP's project, Le Coteau en Commun, proposes to Villejuif environmentally friendly habitat and intergenerational links. Close to the landscape, the structural framework of the wooden project is very flexible and adapts to life cycles. The architect NICOLAS MICHELIN - ANMA and the ATELIER ALTERN (landscape designer) have thus designed a variable geometry habitat based on a shared cocoon system (units of up to 30 dwellings) with a room in excess of 15 m², which can be reserved on request.
Le Coteau en Commun also innovates through the creation of inhabited porches or perched terraces, shared between 2 or 3 dwellings, places of exchange and communal life, to which is added a programme that encourages the maintenance of an intergenerational link.
Connected homes :
>> Fruit of the collaboration between SOGEPROM HABITAT and VINCI IMMOBILIER with the architects DGLA, DANIEL VANICHE, MFR ARCHITECTES and the landscaper LAND'ACTthe Bongarde Village in Villeneuve-la-GarenneThe project, which is part of the "mixed neighbourhood" project, responds to the objective of a mixed neighbourhood by rebalancing the offer between private and social housing, attracting a new population and also providing an answer to the creation of residential pathways, thus preventing the departure of the middle classes or CSP+, due to a lack of suitable housing. The project thus presents a program of progressive housing, responding to the residential paths of families, combined with a proposal for connected housing allowing to evaluate and optimize its energy and water consumption (ECOSIM) but also to improve living together thanks to shared delivery solutions such as connected lockers or thanks to the development of shared services and a network of mutual aid.
Ecotone project in Arcueil 

The new nature square in the city

A source of biodiversity, an ally in preventing and protecting against floods, a lever for reducing heat islands, nature in cities is adorning itself with new virtues that have been forgotten or ignored, offering territories a cross-cutting approach to adapt cities to climate change or prevent the major urban challenges of the future. Corridor for biodiversity, useful and productive nature, a tool for resilience or the fight against climate change... without losing sight of the fact that there is no single solution or model but very specific local contexts, the Greater Paris Metropolitan Area pays particular attention to the different ways of bringing nature back to the city and to its uses.
>> From the association of DUNCAN LEWIS ARCHITECTURE, OXO, PARC ARCHITECTES and TRIPTYCH, the Ecotone project in Arcueil The jury's attention was particularly drawn to its innovative use of biomimicry to meet the challenge of transforming the Côteau d'Arcueil site, located on the outskirts of Paris, visible from the A6, exposed to noise and pollution.
Ecotone Project
Thanks to the shared expertise of a scientific committee made up of CEEBIOS (European Centre of Excellence in Biomimicry), ENGIE LAB CRIGEN and the MUSEUM D'HISTOIRE NATURELLE or NOVOBIOM, an expert in soil remediation, the project uses nature as a mentor rather than a constraint.
The Ecotone team erases the boundaries between city and nature through its architecture inspired by the structural and thermal qualities and uses of natural habitats such as bird's nests and honeycombs; through its elaborate organization as an ecosystem whose programmatic elements complement each other in a logic of circular economy; through the use of the capacities of mycoremediation for the enrichment of fertile soils; via the use of depolluting plants on roofs and facades for water and air treatment or an innovative bio-inspired pump; via the exploration of the notion of epidermis to ensure acoustic comfort near the motorway; or via the mobilisation of renewable energies and the use of plant cover to improve the thermal quality of the building.
"Our project is to create a link between the city and nature on this privileged site and to build a building that acts as an interface between these two environments. This transition zone between two ecosystems is called an ecotone in biology. »
The world embodiment of timber construction and the sustainable city, ECOTONE will be the largest wooden building in Europe. At a time of global ecological crisis, ECOTONE is destined to become an emblem, a strong signal of the commitment of Paris and its metropolis.
ECOTONE is an accentuation of the relief, two hybrid hills that marry trees and plantations to the building. The latter takes the form of a building terraced along the slope and hollowed out with patios allowing the interior lighting of living and working areas.
The programme will consist of a 65,000 m2 tertiary sector centre to provide a healthy and high-quality working environment for users, local shops for the benefit of the entire district, a responsible catering centre, a health centre and a sports centre to make the well-being of users an essential issue, and a hotel to enhance Arcueil's tourist appeal and meet the needs of today and tomorrow. Finally, a residence for researchers and young working people and a crèche help to strengthen the intergenerational link and make Ecotone a solidarity project.
>> The Terre d'Eaux project in Sevran, is reviewing our report on water. In this project proposed by the developer LINKCITY, the architects JACQUES ROUGERIE ARCHITECTES ASSOCIESMUOTO, MATTHIEU GELIN ET DAVID LAFON, JULIA WINDING and the landscape architects ofINTERSCENEThe Montceleux land is a network of large landscapes, landscapes and buildings built around and from the living environment of the water.
In addition to the development of a large water park, the aim is to encourage the emergence of a mixed neighbourhood, offering a high quality of life and setting an example in environmental matters. By opening up spaces and creating continuity by connecting the banks, the Terre d'Eaux project proposes landscaped paths that adapt to the water in order to regain "the use of slowness". Market gardens, water gardens, riparian areas, orchards, 28 meadows and edges punctuate the organization of the site, the project asks the buildings to adapt to the natural spaces and will draw from the water the energy necessary for the site to function.
>> Le Coteau en Commun, in Villejuif, preserves the site's ecosystem and blends in with the landscape thanks to the structural framework of a very flexible wooden project studied by GAUJARD TECHNOLOGY that adapts to the topography of the place and the life cycles of the inhabitants. Right from the early design phases, the ANMA architects' studio's preference was for a construction of compact, narrow and reasonably high building forms which, in accordance with the recommendations of the LIGUE DE PROTECTION DES OISEAUX (team member), allows the development of biodiversity through maximum soil release and the assurance of a high quality living environment within the programme. Reconnecting with nature as a responsible production site
>> Agricultural, associative and residential, the Ressources Toit project, proposed on the Leclerc Army site in Morangis by PARIS SUD AMENAGEMENT, PO & PO WORKSHOP (architect) and LIVING ROOFS (urban planner and landscape gardener specialising in urban agriculture), innovates through its approach (re)reconciling urban space and agricultural activity in a spatial and social logic, by creating synergies of uses (short circuits, participatory gardens, shared composters).
Convinced that agriculture can enrich the construction of the city, the Ressources Toit agri-urban ecosystem will allow the installation of a farm on a fallow land and the construction of new housing in place of the site's old industrial buildings.
Residential and associative premises, located along the residential avenue of the Leclerc Army, are organized in the heart of the island, around a shared central space planted with fruit trees, which is then extended at the bottom of the plot by a diversified farm. The agricultural program will consist of a main area of bio-intensive market gardening, greenhouses, a fruit hedge encircling the plot, a henhouse, an apiary and, eventually, a grazing area. This diversified agricultural programme will operate in a logic of ecosystem and reciprocal contributions. The interactions will then contribute to the resilience of the system.
>> Designed by COBE and ADIM ILE-DE-FRANCE, the V.O² project in Vaucresson has the ambition of an exemplary and demonstrative eco-neighbourhood at the service of environmental excellence. On this Yves du Manoir site, on the edge of a state-owned forest, the project proposes a cohabitation between collective housing, based on bioclimatic and energy innovations, and food crops. DALKIA is setting up an innovative heat recovery system using the fatal energy from the A86 tunnel located in the immediate vicinity of the site and MUGO is developing a participatory agroforestry project at the heart of the programme.
In dialogue with the urban project and its inhabitants, the cultivated land takes back its rights and creates social links, beyond the 2 tons of fruit and vegetables that will be produced each year.

The urgency of resilience

To date, 70% of the world's cities are already experiencing the effects of climate change or are at risk. The Greater Paris Metropolis is not free of all risks, as the great flooding of the Seine last year reminded us, by way of example. As a member of the 100 Resilient Cities, the Greater Paris Metropolis is pursuing a proactive policy in this area, particularly in terms of flood prevention (GEMAPI). As an echo of this, certain projects of Inventons la Métropole du Grand Paris have been selected for their quality in terms of resilience. Pollution risk, flood risk, quarry risk... the Greater Paris Metropolis must know how to prevent, adapt its urban projects and create the resilience of its territory. Several projects have been able to turn these risks into remarkable opportunities for innovation and adaptation.
Controlling the risk of pollution
>> Speaker on the conversion of the EIF factory site, a landscaped area witnessing the manufacturing and urban development of Montreuil (skin degreasing plant), the Oasis des Murs à Pêches (Fishing Walls Oasis)The project, led by BOUYGUES IMMOBILIER and designed by FRANCOIS LECLERC, has thus been able to transform the constraint of heavy industrial pollution into an area of innovation. Because of the former activities practiced on the site and using aromatic solvents, the industrial pollution has strongly impacted the design of the project, both in its programming, its balance and its temporality. Refusing to export its pollution to another site, the Oasis des Murs à Pêches team showed inventiveness and proposed an innovative solution for in situ depollution by bioreduction (degradation of pollutants by stimulating bacterial activity) and venting (a process for extracting volatile pollutants from the soil).
Due to the constraint of a strongly prevailing industrial pollution, BURGEAP, engineering and design office of the group, has made a strength of innovation and creates an important reference for future urban projects on polluted sites.
Coping with the risk of flooding
>> In Nogent-sur-Marne, the REV'N'RIVES project had to deal with several elements including two main constraints: the site's location in a changing urban zone (ZUM) meaning that the regulations for this zone are likely to change; the submission of the site to the flood risk prevention plan (PPRI). Conducted by SOGEPROM, the REV'N'RIVES project thus had to deal with an exceptional landscape and setting, which nevertheless required the project to be designed to integrate the essential components of scalability and resilience. The team took advantage of this and proposes in its project a landscape show that extends the dreamlike, recreational and historical dimension of the banks of the Marne, while favouring the appropriation of places that favour open spaces; by being in line with the spirit of the "guinguette" through light and modular occupations; and by integrating water as a dynamic element with which to organise the exterior developments in order to "deal with" and not "fear" the risks of floods and high water in winter. The project by architects CHAIX & MOREL, BRUTHER and landscape architect VOGT LANDSCHAFTSARCHITEKTEN AG redesigns the banks and improves the relationship with the Marne. The numerous perspectives and paths (high and low) thus highlight the relationship to the water and create places for relaxation and walks.
Integrating career risk
>> Located on the edge of Clichy-sous-Bois, the Leclaire lots have many assets, including a hillside geography that offers views of Greater Paris in a green setting, but they are also located on a former gypsum quarry of 2.25 hectares.
A constraint that the Metropolitan Belvedere project has been able to transform into potential with great agility in making the choice, thanks to GEOLIA's geotechnical expertise, to concentrate the TVK agency's constructions on the upper part of the land (less impacted by the quarry risk) benefiting from the most interesting views and to allow URBAN ECO to develop the rest of the site in place of urban agropastoralism (managed by ETUDES ET CHANTIERS and the association ESPACES) mixing pasture, orchards and above-ground crops. Agropastoral follies" in the form of light wooden pavilions that can be dismantled complete the system.

Making sport and the Olympic Games Paris 2024 a lever for urban innovation

As a major partner in the organisation of the 2024 Paris Olympic and Paralympic Games, the Greater Paris Metropolis is convinced of the territorial dynamic generated by the organisation of an international event such as the Games, but also by the creation of new or large-scale sports facilities.
Athletes, federations, companies and citizens are mobilising to highlight their territory on D-Day, to promote their know-how and their capacity for innovation. The Paris 2024 bid placed innovation at the heart of its strategy by mobilising the French innovation ecosystem.
For Inventons la Métropole du Grand Paris, sports innovators were also present. Inventons la Métropole du Grand Paris was notably able to mobilise the innovative force of sport on certain sites for a greater reception capacity, a greater mix or for the development of new economic and ecological perspectives.
>> The Terre d'Eaux project in Sevran, created for the 2024 Olympic and Paralympic Games, the very first wave of dynamic artificial surfing in France at the heart of a network of large landscapes offering the site a major dimension. Designed by the architect JACQUES ROUGERIE with the FEDERATIONS FRANCAISES DU SURF ET DU SKI NAUTIQUE - WAKEBOARD, this new wave will be able to welcome both amateurs and professionals of surfing, by offering an adjustable intensity and duration of wave suitable for all sliding practices. This artificial wave and the surrounding water park will be 100% autonomous in water. 100% of the energy needs resulting from the pumping of the water will also be provided by renewable energies. Answering the need to surpass a whole generation, the potential attractiveness of this new equipment is undeniably on a metropolitan scale.
 >> Designed by HARDEL ET LE BIHAN ARCHITECTES and BASE landscaper on the priority theme of youth and sport, the Porte Brancion revitalization project in Vanves and Paris Le Sport, la Nature et le Bois, led by WOODEUM, is creating a 2,544 m² sports facility consisting of 3 futsal pitches, crossfit areas and a sports bar, managed by LE FIVE, of which it will become the flagship. Intended to attract new audiences and residents, this new sports facility will be low carbon, thanks to a CLT solid wood construction, and will also offer a SPORT RECYCLERY operated by an eponymous company.
>> The Pleyel Lights, The result of a collaboration between SOGELYM DIXENCE, SNOHETTA, ATELIERS 2/3/4, BAUMSCHLAGER EBERLE, CHAIX & MOREL, MOREAU KUSUNOKI, MAUD CAUBET and MARS ARCHITECTES on the St Denis site, offers 13,100 m² dedicated to a hybrid offer combining cultivation, sport and business with the aim of creating a new centrality, forging links with different audiences, encouraging the emergence of encounters and innovation or even revealing young talent. This programming is made possible by the association SPORT DANS LA VILLE.
>> The Fabrique des Cultures proposes to La Courneuve, a 7,070 m² Urban Culture Hall. Mixing urban art and sport, the site will offer a wide range of activities such as basketball, climbing, boxing, crossfit and many others thanks to the FIVE and local actors such as, for example, THE CROWN BASKET CLUB, the FLASH LA COURNEUVE (American football) or the DEREK BOXING LA COURNEUVE.
The Halle des Cultures Urbaines plays an essential role in the opening of the Fabrique des Cultures on its territory. It is emblematic of the principle of mutualisation of spaces encouraged throughout the site. Thus, the long-term operator of the sports facilities, LE FIVE (associated with partners depending on the disciplines), will open its facilities on dedicated slots to meet the needs of local associations for additional space.
>> The Parks on Stage project on the Rungis Bridge site also integrates a large 25,000 m² facility: the Digital Stage, integrating an important e-sport component (potential Olympic discipline in a few years?) bringing together players such as TURTLE ENTERTAINMENT, SMART VR or LA SOURCE and new sports leisure activities such as a HAPIK trampoline park and indoor climbing equipment proposed by CLIMB UP.
 >> The Plug & Live campus project in Vitry-sur-Seine integrates a sports centre operated by LE FIVE offering classic activities (fitness) and areas for new urban sports (indoor football, paddle tennis, climbing, etc.), operating over very extended hours to promote social mixing.
