Rooms, houses and the light in them

Houses

A house that waits for the tide

On a bare stretch of the Atlantic coast, the architect Marta Ilves built a single long wall and let the weather finish the rest. We spent four days inside it.

Arrival

You see the wall before you see the house. It runs along the crest of the last dune like a line someone forgot to rub out, sixty-four metres of pale lime that catches the first light long before the sand does. From the road it could be a sea defence, or a ruin, or nothing at all.

Only when the track bends does the house reveal that it is there, folded behind the wall, low enough that the marram grass hides its lower edge. There is no front door to look for. There is a gap in the wall, a little wider than a person, and the path simply goes through it.

“I wanted the arrival to feel like finding shelter,” Ilves says, standing in that gap with the wind pulling at her coat. “Not like visiting a building. You walk along, and then the noise stops.”

The wall

The wall is the whole idea, and almost the whole budget. It is built from a soft yellow stone taken from a field two farms inland, laid rough and then rendered by hand in three coats of lime, the last one barely thicker than paint.

Lime stays alive for years. It breathes out the damp of winter and drinks the salt of the spray, and slowly it hardens again from the air. Ilves left it unpainted on purpose: in a decade the seaward face will be a different colour from the landward one, and she is curious to see which.

In the low sun of the morning the surface shows every pass of the trowel. By noon it goes flat and white, almost blinding. The builders called it the long patience, because nothing on it could be hurried.

The stair

Inside, the house is a single room that turns a corner. A concrete stair climbs along the back of the wall to a sleeping loft, and above it a slot cut into the roof lets in one long blade of light.

At ten in the morning the blade lies across the fourth and fifth steps. By lunch it has climbed to the landing; in the afternoon it slides up the wall and fades. People who stay here, Ilves says, stop wearing watches by the second day.

The treads were cast in place with the boards still showing, so that bare feet find the grain of the timber in the stone. It is the warmest thing in a cold material, and the first thing every guest touches.

The courtyard

Halfway along, the wall opens around a small courtyard paved in the same stone. An olive tree that was here long before the house still stands in the middle of it; the plan was bent twice to keep it.

A shallow pool, no deeper than a hand, runs along one side. It holds the sky on still days and on windy ones it shivers into grey. Its real job is quieter: in August it cools the air that drifts into the kitchen through the open doors.

The shadow of the wall moves across the paving like the hand of a slow clock. In the morning the courtyard is in shade; by four it is full of light, and the olive throws its shadow back onto the lime.

Evening

At dusk the house turns itself inside out. The wall goes dark against the sky and the long window behind it lights up, a single warm line along the dune, the only light for a long way in either direction.

The tide comes in quietly here, over a flat beach, and on the highest springs it reaches the foot of the dune. Ilves set the floor exactly one step above the worst water anyone in the village could remember. So far, she says, the sea has agreed.

We left on the fourth morning, through the gap in the wall. Looking back from the road, it was already a line again, pale, patient, waiting for the light.
