The J House is a very special house; it is located close to the Lake Annecy. Construction meanders through the trees along a pond. The building is entirely made of metal structure, due to the complexity of the house plans. Pierre MINASSAN wanted a project fully integrated with the protected site. The house has very few foundations and rises above the water on one support. The large windows offer views of the entire property. Its flat and green roof allows the entire project to blend into the natural landscape.
