Designed as Urban Architect of the A4 Est Neighborhood, the pro­ject places the school right in the cen­ter of the island, like a land­scape freeing up views and dra­wing all eyes towards it. The gym­na­sium is hid­den under a large green space which the school backs onto, while the play­grounds are clim­bing ter­races and gar­dens, evo­king rice fields plan­ted up a moun­tain side. In order to enrich the bio­di­ver­sity of the island, the inter­ior of the school resembles a frag­ment of a cliff which will soon be cove­red in abun­dant vege­ta­tion. This means that the offices and the apart­ments enjoy a totally open and green view. They them­selves are desi­gned as tools for bio­di­ver­sity: soli­tary bee­hives have been ins­tal­led on the roof­tops in an effort to pro­mote pol­li­na­tion, huge col­lec­tive plan­ters and pots are dot­ted den­sely across the ter­races of the apart­ments and offices, bird­fee­ders have been pla­ced in the spaces out­side the uni­ver­sity resi­dence. The macro lot is gra­dually being colo­ni­zed by its very diverse users within dif­ferent time­frames but with a great deal of inter­min­gling. Residents, school chil­dren, office wor­kers, but also hed­ge­hogs, sun­flo­wers, bees, small birds of prey and pop­pies are all appro­pria­ting the space that they share.
