Praxis Anatomy

Spatial Anatomy

Stone, light and shadow, composed to the half-millimetre. Each surface is a decision you can feel before you can name it.

Praxis discipline · Phase mapping

Four phases

Methodology

Excavating Space

Every commission moves through the same four phases. None of them can be rushed, and none of them ever really ends.

01 / Listen

Topography

Direct dialogue with geological strata.

Direct dialogue with geological strata.

We walk the site in every season, reading fault lines, drainage and the path of the sun before a single line is drawn.

02 / Draw

Chiaroscuro

Studies in charcoal and cast plaster.

Studies in charcoal and cast plaster.

Form is found in light and shadow first. Plaster models are cast, carved and photographed until the void feels inevitable.

03 / Build

Execution

Zero-tolerance stone assembly on unbuilt ground.

Zero-tolerance stone assembly on unbuilt ground.

Our own masons and engineers stay on site from excavation to the last joint, holding every course to the half-millimetre.

04 / Live

Patina

We come back every spring for ten years.

We come back every spring for ten years.

We return every year. Stone darkens, timber silvers, and the building settles into the landscape it was carved from.

In winter the house holds the light until four. We didn’t know how much we needed that.
