Constance Guisset Studio has designed Suchaillou, a troglodyte shelter inspired by the local geology of Haute-Loire in France.

This project is a troglodyte shelter conceived to fit in a landscape of 'sucs', a special geological formation linked to ancient volcanic activity in this region of France, taking its name 'Suchaillou', which translates as 'little suc' in the local dialect.

"Made from dry stone, [Suchaillou] was created thanks to the involvement of a local team, bringing together a wide range of partners," said Constance Guisset Studio.

The surrounding area has been designed to take full advantage of the landscape, with benches sprouting from the walls and a fountain created by the artist Lucie Delmas.

The interior space has been optimised to accommodate two people as comfortably as possible, while at the back, a stone gong invites visitors to experiment with the acoustics of the phonolite corbelling.

Above the door, a large oculus made of shot-blasted glass with a gradual transparency lets in the light and the view of the sky.

This project has been longlisted in the small project category of Dezeen Awards 2025.
