Four rules we have not changed
What the stone decides
01
Site
The quarry is the brief.
Before the section drawings, we walk the site. The granite that comes out of the excavation is the granite that goes into the building — no transport, no substitution.

Mass
Mass before mood.
A wall is sized for what it carries, not for what it expresses. Lighting and atmosphere arrive after the load path, never instead of it.
Wall thickness420 — 600 mm

Joint
The shadow joint is the ornament.
Where two materials meet we open the gap, not close it. A 20 mm reveal does the work a moulding used to do, and ages without retouching.

Time
Finish is what weather makes.
We specify the cut — split-face, sawn, bush-hammered — and then leave the surface to the rain. After fifteen winters the building looks correct, not new.
