A structural-glass extension — a glazed garden room, a glass link between old and new, or a frameless ‘glass box’ — can add living space to a Holland Park house while barely interrupting the building or the garden. Slimline glazing and minimal framing let light flood in and let the original rear elevation still read behind it.
Glass is a demanding material to build well. It has to meet modern thermal and safety standards under the Building Regulations, the structure must carry and brace large panes safely, and every junction has to be detailed to stay weather-tight. In a conservation area the lightness of glass is often an advantage, but the scheme still needs planning permission and a sympathetic design.
We design the glazed addition to suit the house, win the consent, engineer the supporting structure, and build it to a precise, weather-tight and thermally compliant finish — all in one contract.
Glass rewards precision — structure, thermal performance and detailing decide whether it works.
In a conservation area a minimal glazed addition can sit lightly against the original elevation.
Large glazing must meet modern Building Regulations for heat loss and safety.
Big panes need a structure designed to carry and brace them safely.
Every junction is detailed to stay weather-tight — glass is unforgiving of poor work.
