Coucoo Cabanes four new cabins complement the existing twenty-five implanted over a 150-hectare site in Franche-Comté, France. Constructed over three levels housed in a protective envelope, the cabin’s design is reminiscent of a bud just before it blossoms: the external structure opens up to reveal the interior spaces, sheltered but open to the surrounding landscape.

The first level, raised on stilts, opens onto the view to a vast, protected terrace allowing guests to live outside, sheltered from the sun and rain. The second level houses the bedroom. The open bay windows allow the space to be naturally ventilated, whilst enjoying the views. The third level features a Nordic bath. The terrace allows guests to soak up the views whilst reconnecting with the ever-present natural world.

The cabins respect the existing biodiversity as they emerge from the trees on the periphery of the nature reserve. Whether open or closed, their façades – the two protective envelopes – offer unobstructed views of the forest and lakes. The outer structure is either closed or perforated. It acts as a filter, providing shelter, framing views, protecting from the sun and wind, and creating a strong connection with the natural world in such proximity.

The wooden furniture has been specifically designed to blend in with the architecture of the cabin. Positioned in the centre, the bed also serves as a space divider in the bedroom. The lounge area is created by a simple curved bench and a coffee table. Towards the back of the cabin, screened by the headboard, the washbasin and dry toilet have been integrated. Finally, the wardrobe and shelving unit complete the layout in the opposite corner.

Thermal comfort, provided by the high-performance insulation of the envelope, is enhanced by the openings on the opposing façades. This allows cross-air circulation, further assisted by a fan positioned above the bed. The space is optimised, predominantly open plan, and offers a constant visual connection with the landscape outside. The location of each cabin is determined by the opportunities and vulnerabilities of the site. The aim is to protect the natural environment whilst creating the best possible experience for the guests.

The cabins were constructed by MCF Bois, a company specialised in timber framing, whose workshop is located just one hour and 15 minutes from the Grands Lacs site. The chosen type of wood was Douglas fir, and the trees were felled less than 30km from the workshop. The cabins were prefabricated in the workshop, then transported to the site. This prefabrication process, together with the use of adapted lifting equipment, meant that the construction time on site was reduced and the impact on the terrain was minimal, thereby helping to protect the site and its biodiversity.

The Coucoo Cabanes project supports the local economy, reduces its carbon footprint thanks to short transportation distances, and promotes the region’s traditional craftsmanship.
