Completed Project

Full-house refurbishment — Belsize Park Gardens, NW3

Five-storey period home transformation with basement conversion, extension and loft works.

Completed Belsize Park Gardens whole-house refurbishment

The published case-study record describes a Camden conservation-area project combining basement, extension and loft works in a single whole-house programme.

How the whole-house work was sequenced

Our design team proposed a comprehensive strategy that would unlock over 40% additional living space through a basement conversion, a rear extension at garden level, and a sympathetic loft conversion — all within Camden Council's strict conservation area guidelines. Every intervention was designed to complement the original Victorian architecture while delivering a thoroughly modern family home.

The construction programme required careful sequencing to manage the complexity of working simultaneously across five floors. Structural works began from the basement up, with underpinning and tanking completed before the ground-floor extension steelwork was installed. The loft conversion followed, with new dormers designed to match the existing roofline profile along the terrace.
