This 56-living units building is located in an urban renewal zone in the « grand-Paris » area, in Savigny-le-Temple (Seine-et-Marne). It is innovative in several ways: firstly, it is the result of one of the first BIM competitions launched in France in 2014, and it was on this occasion that the agency took the turn of this building data modelling system.
Not content with this novelty, the dwellings are also aiming for the passive level and are experimenting with an innovative construction technique coupled with bio-sourced materials: prefabricated wooden facades, which until now have not had any technical approval for a building of more than two levels, are placed on the structure and then insulated with wood wool. In addition to these two precursory aspects, the volume is well integrated into its site and the programme is treated in superimposed layers to reduce the thickness of a passive volume.
Just a stone’s throw from the 1970s Miroir d’Eau shopping centre, which is due to be demolished and rebuilt in the near future, the building develops in a U shape with three sides facing Avenue Charles de Gaulle and the future car park of the new shopping centre. The heart of the block is treated as a vast green space on two levels and opens up widely to the south-east towards the lake below. A passageway connects the street to this green courtyard, which contains the three access halls to the flats. The programme is spread out in three horizontal strata that can be seen in the façade. The shops on the street are lined up along a wide glazed ground floor. The three upper levels are made up of flats and alternate on the façade between windows and vast loggias connected to the living rooms and kitchens of the large flats. The attica also hosts flats in the form of pavilions clad in galvanised steel.
