Architectural approach
The building’s archi­tec­ture is ins­pi­red by the shape of a but­ter­fly, with ter­races arran­ged like a fan, resem­bling outs­tret­ched wings. This layout allows opti­mal natu­ral ven­ti­la­tion and offers unobs­truc­ted views of the urban land­scape. The building’s prow conceals win­ter gar­dens and log­gias, pro­vi­ding light and pri­vate out­door spaces for resi­dents.

Urban and envi­ron­men­tal inte­gra­tion
The pro­ject inte­grates har­mo­niously into Nanterre’s urban fabric, prio­ri­ti­zing pedes­trian cir­cu­la­tion and redu­cing the buil­ding foot­print. This approach frees up space for public areas and green zones, the­reby contri­bu­ting to resi­dents’ qua­lity of life.

Conclusion
The Papillon hou­sing illus­trates Loci Anima’s abi­lity to design resi­den­tial pro­jects com­bi­ning aes­the­tics, func­tio­na­lity, and envi­ron­men­tal res­pect. This pro­ject reflects the agency’s com­mit­ment to sus­tai­nable and inno­va­tive archi­tec­ture adap­ted to contem­po­rary needs.
