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.
Sourced within   1.2 km of site
Imported stone   0 %
02
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 thickness   420 — 600 mm
Cantilevers   avoided
03
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.
Reveal depth   20 mm, typ.
Trims, mouldings   none
04
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.
Sealants on stone   none
Design life   100 yrs +
