Development of 49 Minergie-A/P Eco flats in the PPA Bussigny Ouest.
The Alter Eco project proposes a set of two buildings around a common distributive heart and a collective garden. It forms a cooperative, friendly and lively ensemble and offers a pleasant place to live where all the flats are in dialogue with the outside through generous corner balconies.
The wood construction project is compact, rational and economical in order to meet the high requirements of the CMHC and to be sustainable and responsible.
