Massy :

Massy is a green and dynamic city, with over 160 hectares of green space and 367 associations. Third largest city in Essonne with over 43,778 inhabitants, today it is served by the RER B and C, a TGV station, main roads (A10, A6, D118, N20) and is located near Orly airport. At the heart of a communication node and with many public infrastructure, the city has become a major economic center of the island of France attractive for large companies such as Alstom, Thales, Carrefour …

Massy is also the southern gate of the Grand Paris and will benefit as such train-tram. Anticipating the changes the city through its public developer, the SEMMASSY, has launched many urban development projects whose Massy Atlantis project, Franciades Opera and Vilmorin district. The call for proposals relates to a real estate program neighborhood Vilmorin.

Vilmorin district:

Set within the grounds of the old nursery Vilmorin close to the RER C station, the neighborhood Vilmorin has been designed to create a residential feel favorably by both existing residents and by those to come. The urbanization of land Vilmorin aims to realize the construction of a joint program focused primarily on the construction of housing and shops, not excluding the host tertiary activities, and leisure; a program whose density takes into account the proximity of the cluster of stations and surrounding residential neighborhoods. Particular attention was paid to public spaces with the construction of various public spaces linked together:

  • Public gardens created from east to west of the district and leading to a green amphitheater (need for retention)
  • an email opening on an urban site and animated by proximities of businesses located in the foot of buildings

The SEMMASSY wanted to put nature at the heart of the city in order to create spaces facilitating exchanges between the inhabitants. This first urban agriculture initiative on roofs is a pilot project that can be replicated.

DReAM is the owner of that property development located in the neighborhood Vilmorin. This project is in continuity, the search for well-being of people through green public areas favoring community life. The team wishes to allow future residents “to live in the sky, to inhabit the body of the buildings and inhabit the floor” translate into more specifics in the frame. This project of about 7550m2 SDP will include 112 apartments distributed in 3 buildings. Fragmentation of “living areas” in different sizes allows, despite the significant size of the operation, to live in a “small community”. Flat roofs are habitable with private and shared spaces. The program meets the requirements of the RT 2012 and H & E certification. Architect: SOA Architects

The proposed project:

Reintegrate agriculture in the city and improve the lives of the community in buildings by exploiting Rooftop cultures. The design of a 100m2 shared garden on flat roofs of the buildings will help to develop social ties between the occupants.

  • edible vegetation (vegetables & shrubs) as part of a collaborative saving mode (recycling, alternative consumption)
  • creating an ecosystem favorable to the recolonisation of a natural fauna (bees, birds ….) and / or a mini farm (hen …)
  • involvement of users / residents of buildings. (participation in harvesting, gardening lessons, …)

Enhance the resources of the building: the proposed innovations should enable the development of local resources by incorporating:

  • recovery of waste: substrates and community composting

recovery of rainwater on the roof.

  • la valorisation des déchets : substrats et compostage collectif
  • la récupération des eaux de pluies sur le toit.

The SEMMASSY: created in 1983 to meet the operational needs of the City of Massy, ​​we have since developed a policy focused on urban quality of life, livability and contemporary architecture. It now allows us to provide a specific response to the new challenges of development and construction in the territories where we operate. Because we consider that touches the city must give envy, pleasure and quality, we are leveraging our status Local Public Enterprise to combine responsiveness, economic performance and general interest.
