Specialty and Bespoke Systems

Curved, arched and one-off assemblies developed when a standard system cannot hold the design intent.

Bespoke curved steel window with radial glazing pattern in a pale stone stairwell

Overview

Some openings are not catalogue conditions. Radial heads, curved plan geometry, oversized single lights and landmark replication require development from first principles.

These assemblies are documented with the design team from concept sketch through fabrication drawing so that intent survives the process.

Applications

  • Curved and radial openings
  • Landmark replication
  • Rooflights and clerestories
  • Oversized single lights
