They desire spaces bathed in light, while remaining discreet and blending seamlessly into the calm and preserved environment around them. Their vision goes beyond aesthetics: they wish for an environmentally friendly house, self-sufficient in terms of energy and water, to create a sustainable living space in perfect symbiosis with its environment. The two extensions are demolished, revealing and enhancing the stone of the original building. The height of the original building's gutter determines the height limit for the new constructions.
A first volume, built with a mixed structure of wood and hemp-lime blocks, houses the living areas. It stretches parallel to the northern boundary of the plot. The entrance, running alongside the stone of the existing house, opens directly onto the garden, while the structure remains discreet thanks to its transparency. This volume, generous in height, is divided into three sections by functional blocks, separating the entrance, the living room, and the kitchen/dining area. On the south side, the facade is largely glazed and protected by a cantilevered roof designed to limit summer sunlight.
On the north side, small openings create a sense of cross-views. The volume dedicated to the sleeping areas is designed with essential simplicity. Built entirely of hemp-lime, it blends discreetly under the "wings" of the main volume, extending towards the rocks where it finds shelter. The master bedroom, intimate and soothing, is nestled in the undergrowth, offering a true haven of peace in harmony with the surrounding nature. To the north, in the less prestigious part of the plot, the garage and workshop are located, away from the heart of the house but perfectly integrated into the landscape, forming a harmonious complement.
In the existing house, fully insulated with bio-sourced materials such as sprayed hempcrete for the walls and wood wool for the roof, there are a bathroom, a laundry room, and a guest room. Two rainwater harvesting tanks and a treatment system ensure water self-sufficiency. The solar heating system, combined with a backup wood stove with a boiler, provides gentle thermal comfort in winter. Canadian wells and decentralized dual-flow ventilation ensure natural ventilation.
