Faced with railway rights-of-way, in the Zac Clichy-Batigolles undergoing major transformation, the proposal aims both to be a strong urban entity and to offer good domestic qualities. The project organizes 98 dual and triple orientation dwellings.

The built environment offers several fragmentation scales. Like the configurations of semi-detached buildings aligned along a street producing a vibration and a rhythm vertically, here the fragmentation of masses operated horizontally scans and provides the volumes laid, from the ground to the sky, one on top of the other.

In excess of the thickness of the first compact enclosed-covered volume, a second layer of extra-large "winter gardens" is hung and creates fully glazed and openable outdoor spaces. From 1 to 2 metres deep depending on the orientation and floor, and extending over the entire shelf of each apartment, all the apartments benefit from 10 to 40 m² of additional outdoor space. It is also a way to distance and offer privacy to the residents; street side on the lower floors and in front of the office operation just across the street.

In addition, this "thermal thickness" saves 15 to 20% of heating needs. The figures speak for themselves: an energy balance of 32 kWh/m²/year has been achieved.
