How can we improve our lifestyle towards a greener one without compromising on our wellbeing? How can we manage to get rid of some comfort to only keep what is necessary? How can we live a simpler life on a daily basis, and therefore a more meaningful one? These questions went through the Harlé family’s mind when they decided a few years ago to build their house in Crach’, Brittany. A few kilometres away from the gulf of Morbihan, in a region that is very conservative, and therefore very demanding in terms of architecture, they had to fight for their project to be approved, indeed here, there is no slate roof or stone wall, but simple and raw materials such as wood and metallic sheet.
