The Principles of Enduring Form

1
Mass before detail
The block is dressed by hand before any surface is refined. Proportion governs first.
2
Light as material
Shaded stone reads gray, never gold. Every surface is calibrated to the cool midday hour.
3
Joints that speak
A three-millimetre mortar line is a deliberate act. Each course legible from across the square.
4
Time in the surface
Tool marks are not flaws. Chisel strokes register the hand fifty years on, and will register a hundred more.
