Creation of 12 housing units for Seniors and PMR in the municipality of St Lupicin 39170. The request of OPH St Claude is to carry out a BEPOS project in wood frame and straw. The project management (Elie Bouche architect DPLG commissioned in November 2014 assisted by thermal engineer Romain Claret – PLAN 9) presents a team and leads the project to design a passive structure labeled by the Passiv Haus Institute. At the initiative of the project (2013) the BEPOS objective made it the first BEPOS social housing project in Bourgogne-Franche-Comté.
