The Canopy House

One roof, and a garden underneath it.

Overview

The Canopy House is one gesture: a long, folded roof of larch that floats over the whole plan and reaches out to shade the terrace. Its upper planes are planted, so from the hill above the house reads as garden.

Beneath it, the rooms are simple boxes of white stone and timber screens, set back from the edge so the canopy does the work of walls. In summer the house is open on every side.

We gave the house one roof and let the garden have the rest.

Materials

Made of few things.

Three materials, chosen at the source and left to age. Nothing is painted to look like something else.

  • Charred timber boards with a deep black grain

    Charred Oak

    Scorched the old Japanese way, oiled, then left alone. The char is the weatherproofing, and it deepens with every winter.

  • Low-iron glass reflecting trees and warm interior light

    Low-iron Glass

    Without the green cast of ordinary glass, so the landscape reads true from edge to edge.

  • Fair-faced concrete with tie holes and formwork joints

    Fair-faced Concrete

    Cast once, in timber formwork we draw ourselves. The tie holes stay: they are how you read the pour.
