Text description provided by the architects. This nautical base is situated on the Vendée coast in the midst of an exceptional landscape: next to the coast, nestled between pristine dunes, and close to a rocky cliff. To install sports facilities ever so discreetly in the heart of this eco-sensitive site, the nautical base is hidden in the existing dune, its oceanfront facade is the only one that is an exterior facade.

The reception areas, offices, and activity spaces are placed along this facade to take advantage of exterior views. The storage spaces, lockers, and toilet facilities are located back in the center of the dune with natural light wells that traverse a planted roof structure.


The overall structure is in reinforced concrete and the exterior facade treatment creates continuity with the existing retaining wall elements of the dune by the use of azobé planks, a very resistant exotic wood that is used in construction permanently exposed to the marine environment (decks, walkways, etc.).
