Introduction

London homeowners face unique challenges when it comes to glazing — from period properties with sash windows in conservation areas, to modern developments requiring structural glass installations. Getting the right advice before you commit can save you significant time and money.

At BuilderFix Glazing, we have completed thousands of glazing jobs across Greater London and Surrey — from emergency repairs in Kensington and Chelsea, to bespoke walk-on glass installations in Mayfair and Belgravia. This guide is based on real experience and the questions our customers ask us most often.

In Depth

Hampstead presents some of the most demanding glazing work in London. The combination of a very high concentration of listed buildings, a large and strictly enforced conservation area, a discerning and architecturally aware client base, and some of the most complex period window configurations found anywhere in the capital means that glazing in NW3 is not a job for generalists.

The Hampstead Conservation Area covers the vast majority of the village and much of the surrounding streets — including the Heath Extension, Well Walk, Flask Walk, and Holly Hill. Within this area, any change to the external appearance of a window — including replacing frames or altering glazing bars — requires either permitted development compliance or, for listed buildings, listed building consent. We prepare the necessary documentation and can liaise with Camden Council's planning department on your behalf.

Sash window work is at the core of what we do in Hampstead. The Georgian and early Victorian properties in the NW3 conservation area typically have six-over-six or eight-over-eight box sash windows — elegant, well-proportioned, and often in poor repair after decades of repainting and swelling. We carry out full sash window restorations, including new sash cords, draught stripping, spiral balances, and slim double-glazed units, all maintaining the external profile and appearance required by conservation area guidance.

For those Hampstead properties that have been extended or modernised — particularly the large detached homes on the roads north of the village — the glazing brief is very different. Structural glass floors over basement light wells, frameless glass balustrades on roof terraces, and ultra-slim aluminium bifold doors that open entire rear elevations are all projects we have completed in the NW3 area. These require a higher specification of glass and more precise structural planning, which we coordinate alongside structural engineers where required.

If you own a property in Hampstead or Belsize Park and are planning any glazing work — from a single sash repair to a full basement glass floor — we recommend beginning with a free site visit. Hampstead properties vary significantly in their heritage status, and understanding the planning position before you commit to a specification will save time and cost.
