The concrete volume of Kitayama House cantilevered over the trees.
1/3 The living room hangs over the slope; only the retaining wall touches the ground.
A long concrete room with a cedar door and a low window onto the mountains.
2/3 The long room, with a bench under a window set at sitting height.
A corridor lit by a triangular window over a pool.
3/3 The corridor: a triangular window over the pool throws a moving shape onto the wall.

A house that leans out of the hillside to meet the view.

The plot falls eleven metres from the road to a stream in the hills north of Kyoto. Rather than terrace the slope, the house rests on a single retaining wall at the top and lets the rest of the ground stay wild.

The living room is a concrete box cantilevered nine metres over the trees. Below it, a garden room with a gravel floor opens straight onto the forest.

The slope

Only the retaining wall touches the hillside. Everything else floats: the trees grow back under the house, and from the road it reads as a single horizontal line in the forest.

Section A. The living room hangs from the retaining wall; morning light enters below the roof slab and reaches the back of the room.

Light

Windows only where the light is worth having: a long east window for the morning, one opening at the end of the living room for the valley, and a triangular window over the pool for the afternoon.

Material

Board-formed concrete inside and out, cast against cedar planks so the grain stays in the walls. Cedar doors, gravel floors, nothing painted.

Structure

The cantilever is a pair of deep concrete walls acting as beams, anchored in the retaining wall. The glass at the end carries no load at all.
