Île Extenso

Housing and commercial space

This complex, built on the site formerly occupied by the Calberson trucking company, is composed of 154 apartments including 54 in privately owned rental units owned by the Caisse des Dépôts et Consignations. The ground floor houses 5 commercial units.

In a commercial area along the Boulevard de la Prairie au Duc, a hanging garden was created for the residents of the 7 buildings that surround it. For this site, the developer wanted to build large rental units, and the Caisse des Dépôts et Consignations, as a long term investor, purchased 54 two-, three-, and four-bedroom apartments.
