Looking for glass extensions in Harrow? S&K Glazing has been installing across Greater London for over a decade. A frameless glass extension creates the ultimate connection between home and garden — full-height glass walls, structural glass roofs, and minimal framing for an almost-invisible enclosure. For Harrow properties near Heathrow Airport (LHR), we can specify acoustic-grade glass to reduce aircraft noise alongside thermal performance.
A frameless glass extension creates the ultimate connection between home and garden — full-height glass walls, structural glass roofs, and minimal framing for an almost-invisible enclosure. S&K Glazing designs and builds bespoke glass box extensions for kitchens, dining rooms, garden rooms and pool enclosures across the UK.
Harrow sits under Heathrow's northern flight paths and near the busy A40 — our acoustic glazing is heavily specified in HA1, HA2 and HA3 postcodes. Plus extensive heritage work in Harrow on the Hill conservation area.
For doors and glass extensions in Harrow, residential property style typically drives the design brief across London — whether that's contemporary aluminium bifolds spanning a garden-facing rear elevation, slim-frame sliding doors that maximise glass area on a modern extension, or heritage French doors fitted to a period façade. Most commonly we're working across A40, HA1, HA2 and HA3 postcodes. Typical lead time from survey to install: 4-6 weeks for standard configurations, 8-10 weeks for bespoke or large-span builds.
We visit your home, discuss your vision, and produce concept sketches and CAD plans. For complex projects we can introduce you to our partner architects.
Structural glass extensions require specialist structural calculations and (usually) planning permission. We handle both — typical timeline 8-12 weeks from concept to consent.
Glass panels are toughened and laminated to structural specifications (often 24-32mm thick). Lead times 6-8 weeks. Steel structure (if exposed) manufactured in parallel.
