The programme consists of the construction of an apartment building. The new apartment building espouses the morphology of the terrain, the ground plan in a U-shape enabling the historic urban fabric to be harmoniously woven in with the location of the chateau and the thoroughfares ringing the park. The care devoted to integration is also expressed in the work on the facades which is similar to that on the buildings that used to be on this site. This configuration induces an indented reading of the volume, as opposed to a monolithic bar-structured building. Particular attention has been paid to the finish of the roofing provided by an alternation of metallic roofing and green, ecoroofing. The ensemble offers a wide range of residences, from single bedroom apartments to four bedroom penthouses.
