The site

The plot falls gently west from a quiet road in Holmenkollen, with old birches along the lower boundary and a view toward the fjord over the neighbouring roofs.

The road side is close and busy with school traffic in the mornings. We answered it with a long garden wall in local stone, built where an old dry wall had half collapsed, so the house shows the street little more than a gate and a roof edge.

The building

A cantilevered concrete roof reaches out past the wall and shelters a terrace the full length of the garden.

Below it, the rooms run in a single line behind full height glazing, with the kitchen at the centre and the bedrooms tucked into the hillside. A board-marked concrete stair climbs through the middle of the plan under a long roof light, so the deepest part of the house becomes the brightest. The structure is closed, and the family hopes to move in before the first snow.
