The team behind the execution.
Blending decades of chartered construction mastery, Building Safety Regulator compliance, and tech-driven contractor management with authentic design studio literacy.

Founded by Pierre Williams and George Harris, our leadership structure unites 25+ years of prime UK construction with modern operations, giving interior designers an execution department they can trust implicitly.
