Located lakeside in the Italian Dolomites, this charming barn conversion had to meet the requirements imposed by the conservation area and respect the vernacular character of alpine architecture. We had to completely rethink the interior to carefully integrate a bathroom with a shower into the converted loft space. The design concept follows a simple and effective layout based on four clearly defined zones, aligned with the spacing of the existing larch timber joists. First, a timber staircase runs along the stone wall at one end; second, the double bed and wardrobe occupy the central area; third, the bathroom space; and finally, at the rear, the shower and a storage chest.
