On a walled, sloping site near Santa Maria da Feira in northern Portugal, Branco del Rio Arquitectos turns a cowshed, barn and caretaker's house into one home, keeping the granite and rebuilding above it in timber.
Single-Family Home sits inside a walled enclosure thick with mature trees, on ground that falls away in a long, easy slope. What stood here was a working farmstead: a cowshed, a barn and the caretaker's house, arranged around a courtyard. Branco del Rio Arquitectos left that arrangement alone. The buildings keep their footprints and their relationships to one another, and the new dwelling simply moves into them, distributing rooms according to what each structure already was.
The old cowshed now holds the living spaces. The caretaker's house takes the bedrooms. The barn absorbs the entrance, the circulation, the service areas and the garage. Nothing is forced. The programme follows the bones of the farm rather than overwriting them, so the way a visitor moves through the house still traces the logic of the animals, hay and labour that came before.
The move that holds it all together is a clean split between base and top. The studio keeps the load-bearing granite walls, rough and grey, and above them reconstructs a lightweight timber structure of floors, facades and roof, framed the way the original barns were framed. Douglas fir joists run exposed across the ceilings; board-formed concrete columns carry a covered courtyard where the roof lifts to show its rafters. The mineral base stores heat, the insulated timber shell above it stays light and warm, and the two behave as one climate machine.
Comfort here is mostly passive, borrowed from the farm's own intelligence. Deep eaves throw shade across the granite. A ventilated timber roof keeps air moving. Thick masonry steadies the indoor temperature, now backed by roof insulation and external timber shutters that filter the Portuguese sun. Inside, the palette stays honest: pale plank floors, white plaster, a black steel hearth, a walnut table under two soft pendant lamps. In the bedroom wing a barrel-vaulted corridor opens to an overhead skylight, washing the plaster in daylight.
Granite, timber and lime-based mortars do all the work, laid by local hands over a long build that let the materials settle and the house sink into its ground. Where the living room meets the garden, a raw granite boulder is left in place against the sliding glass, the site refusing to be fully tamed. The result reads less like a renovation than a second life, an old ensemble adapted until form, material and climate finally agree.
