Certainly "invent metropolis" does not have "its" emblematic project, such as "Thousand Trees", major success of contest reinventing Paris. There are some architectural audacity, as in Clichy-la-Garenne, where architect Rudy Ricciotti imagined a tower of thirty floors in concrete bundle and glass, backed to House of people, heritage nugget dating from years 1930. A "mineral tower" whose exoskeleton will be sunk on spot in a gigantic sarcophagus.
However, most remarkable innovations are elsewhere. The size of proposed sites, ranging from 800 m2 to 14 ha (for comparison largest site to reinvent Paris was 1 ha) allows real urban innovations, at scale of a neighbourhood, incorporating in-depth reflection on new uses, economy Circular, resilience, or mobility.
This competition has created a real emulation and has attracted attention to both areas in difficulty and more affluent sites. The projects, of all kinds, follow a real logic of development, focusing on uses more than features, and with an approach to space mixing practices, is enthusiastic Thierry Lajoie, president of Grand Paris Landscaping, who has Proposed five sites. In end, we have great hopes for landscaping. »
On 15 hectares of Triangle of city, Belgian company Bopro Sustainable Investments (BSI), aims to develop a demonstration district of circular economy. Comprising 167 100 m2 of modular offices, incubators, workshops, coworking areas, and equipment and services for assets (gym, health centre, crèche, temporary accommodation ...), site will host companies from Bio. And especially buildings, with positive energy and low carbon, will be modifiable, fully removable. Each "brick" of buildings, each material, chosen for its energy performance and its capacity for re-employment, will be traced and recorded in a raw materials bank. The circular design of project is based on a new relationship to material, now considered a service, and no longer as a good.
Dubbed "Triango", project will also promote development of sustainable mobility, including bicycle parks, self-contained electric shuttles, playful and practical pedestrian paths, or a carpool service. And aware of agricultural tradition of this territory, it will give a central place to high-tech urban agriculture with development of 8 000 m² of aquaponics crops for short circuits, and 2 000 m² of indoor crops For cosmetic, pharmaceutical and textile testing.
Vegetation is also strongly present at "Lab21" — a Laboratory for energy transition and sustainable growth, which will be installed on 13 447 m2 of clock ZAC in Romainville. Carried by promoter Alsei, Agence Franc architect and landscaping horticulture and gardens, this project aims at zero Carbon, zero waste, zero fossil energy and fissile. Just that! While promoting return of nature and biodiversity to city. Mixing dwellings, collaborative workspaces and a third place dedicated to eco-design and sustainable food, building, in classical forms, will be built with biobased materials and according to modular construction techniques. It will be capped with 1 000 m2 of roofed urban farm. On this terrace vegetated will also be installed greenhouses in Bioponie (soil culture on neutral substrate benefiting from nutrient supply by drip).
The Palme of most "nature" project, however, returns to Coteau, in Arcueil. The company Phalsbourg, Duncan Lewis Architecture, OXO, PARC Architects and triptych propose to transform this site at crossroads of A6a and A6b, thus exposed to noise and pollution, in a "Ecotone", a place between city and nature. Biomimetic, project is inspired by nature, in all its dimensions. From an architectural standpoint, it takes form of a storied building in terraces and excavated patios inspired by rmal qualities and uses of natural habitats, such as bird's Nest or bee hive. Roofs and facades will be adorned with polluting plants used for treatment of water and air. To ensure acoustic comfort, notion of "epidermis" will be explored. To improve energy qualities of building, renewable energy sources will be mobilized and a plant cover will be used. To carry out this project, a scientific committee composed of Centre of excellence of biomimicry of Senlis and Museum of Natural History will accompany team.
While also giving high importance to plantations, project "hospitality", in Kremlin-Bicêtre, — a name chosen in homage to a nearby hospital — placing in its heart use, develops a new, flexible and modular approach to habitat. All accommodations will have opportunities for evolution. Their terrace, from a surface of 30 to 100 m2, generously vegetated, in image of a real garden, will be part of "colonization". Without having to file a building permit, each dwelling will be able to extend on garden terrace, with an additional room of 10 to 20 m2 and thus adapt to sequences of life of a family. In addition, in order to meet needs of all purchasers, large dwellings can be divided into two smaller or conversely combined.
This emphasis on uses also leads to many award-winning projects to develop transitory planning on ir site, even before y begin ir development. On site of old embroidered flower factory, at 29 Rue du Soleil, in 20th arrondissement of Paris, in particular, if some of programmes are determined (canteen, offices, lodgings), ors will be defined as gradual occupation of site. The architects ' Office of cliques and slaps and landscaper Christophe Père deliberately made choice to offer possibility to adjust ir project according to experienced uses in situ. Throughout project, user-friendly events will be organized in inner courtyard of site and open to public, in order to test possibilities of place while meeting potential local partners.
Transient planning or not, many winning projects remain to be refined and can still evolve. "On a number of sites, adjustments will be necessary, not hiding a member of jury." Because re were only two laps for examination of files – and not three as for reinventing Paris – it was not possible to ask teams to make all details of particular aspect of ir project. »
