Realized by the pioneer of self-construction Joël Unal according to the project of Claude Häusermann-Costy in 1972, the maison-bulle is on sale for €2,500,000. In the heart of the Ardèche, in the south-east of France, the house deeps in the wild landscape and despite its whiteness blends perfectly into it, looking towards the profiles of Mount Lozère and Mont Blanc.
With an area of 156 square meters, the villa consists of a kitchen, lounge, library, laboratory, and three bedrooms. Each space is connected to the others through two emblematic circulation tunnels. For obvious reasons, it is furnished with custom-made handmade furniture and is also enriched with mosaics and colorful sculptures. All windows are round. Outside it houses a terrace almost as large as the house and a swimming pool.
