UzÃ¨s Sotheby's International Realty has the pleasure to propose exclusively this stunning piece of 20th century architecture. Classed as a 'Monument Historique', the property is considered to be the reference point of a series of 'bubble houses' conceived throughout the world. Antti Lovag and Claude HaÃ¼sermann were the main players in this form of architecture freeing their constructions from straight lines. The building technique involved a layer of reinforced concrete which allowed the creation of free forms, reflecting nature with its round shapes and soft curves. Each area has its function with each section coming from the entrance hall and all being curved or spherical, creating private spaces built around the rocky landscape upon which it sits. Oval windows and 'skydomes' give light and natural ventilation to the property. This living sculpture offers 300mÂ² of living space with each 'bubble' offering a space for either dining, resting or sleeping... Shelves and seating areas are integrated within the architecture seamlessly. By acquiring this exceptional property located in the southern Ardeche, you also gain ownership of an example of an audacious movement of 20th century architecture.
