The Tour de la Porte Chapelle is a new mixed-use development in Paris, France designed by award-winning architectural firm Abalos Sentkiewicz to be completed in 2012. The project was commissioned by the City of Paris as a new urban hub for the area; the innovative building is composed of three main towers that peel off from a multi-purpose plinth with civic, retail, and recreational areas. The towers are divided according to program including housing, offices, and hotel – a very interesting aspect of the proposal is the weaving of programs at the lower floors creating interstitial hybrid spaces.
