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.
Londonderry's 17th-century walled city, Georgian Bishop Street, and Victorian Waterside generate heritage-led glazing demand across BT47-BT48. Listed-building consents and timber sash restoration form the bulk of our work in this Northern Ireland walled city.
For doors and glass extensions in Londonderry, residential property style typically drives the design brief across Northern Ireland — 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 BT47 and BT48 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.
