Description of the project:

The operation is located in Clichy-sous-Bois (a Parisian suburban area) and is part of the urban renewal program of the Plateau de Clichy-Montfermeil.
This approach, formally undertaken since 2004, is today one of the most ambitious signed by the National Urban Renewal Agency (ANRU). It covers a vast area characterized by serious social and urban malfunctions.
The site presents great contrasts; it is located precisely on the area between tall council blocks built in the 60s on one side, and an extended forest on the other. The project aims to resolve the transition between these two components strengthening their relationship in a positive way.
The result is a project that creates a strong bond between the urban neighbourhood and the landscape.
The three blocks are oriented in order to allow at the flats to enjoy in the same time of the forest views in the N/E and of the best orientation on the south side.
The research of the optimal orientation has been the fundamental principle of the design since the very first project sketches. The twisted shape of the plan of the three blocks is the result of this reasoning.
The facade design responds to the orientation and to the specific environmental conditions. The balconies on the south side, large and simples, visually liaise with the existing tall council blocks. The brightly coloured louvre panels on the opposite side liaise with the forest and its beautiful changing colours. The coloured louvre panels wrap around to define the side facades.

The buildings were awarded the BBC French Low Energy Certification on March 2011 (BBC label – 50/65 Kw/h/m²/an).
The main sustainable features of the project are:
– Compact volumes;
– South orientation for most façade openings (344 m2 of the total 595 m2). Despite the peculiar site shape, the project manages at least a south window for each apartment, with 34 of the 48 apartments enjoying large balconies (area 12 m2; length 2m);
– The east and west façade openings are protected by louvre panels to avoid heat gain during the summer;
– Reinforced concrete structure with reinforced internal insulation system and thermally broken cantilevered slab elements and spine walls;
– Condensation gas central heating plant;
– Heating solar panels;
– Rain water management.
