About the project

A steep path linked a harbour town to the cliffs above it. We replaced it with a covered stair hall cut into the hillside, a public room you climb through on the way up.

The concept

A room on the way up

The stair rises in four flights, each ending in a landing with one window to the sea. Climbing it, you see the harbour four times, each time a little further away.

Openings in the roof follow the line of the stair, so daylight walks up the steps with you.

Material and light

Concrete, granite and steel

The walls are concrete mixed with crushed granite from the excavation, so the hall has the colour of the hill it is cut into.

Handrails and lamps were designed by the studio and forged in blackened steel by a smith on the island.

Bedrooms and kitchens face east, so the day begins with low, cool light across the walls.

At noon the sun stands high in the south, and the deep roof keeps the living room bright without glare.

In the afternoon the light turns warm and low, reaching across the floor to the far wall.

At dusk the west windows hold the last colour of the sky while the room slowly falls quiet.

At night a few low lamps take over, and the windows turn into dark mirrors of the garden.
