We are presenting our latest architecture project as a sustainable housing solution. ARCA house solves the impact that standard architecture creates on the local environment and predicts a nomadic lifestyle of new generation. The construction time is reduced to 120 days while the main covering structure is installed in only ten days (and dismantled in the same period). It is a low impact and low cost solution. Place to rest and create, the house offers a comfortable space as a workshop area for temporary projects and research developments in the middle of the Atlantic Forest. Far from home, but feeling at home.
