Structural glass extensions and frameless box rooms
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.

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.
Foundations, glass installation, weatherproofing and internal finishes. Typical 3m × 4m glass box extension takes 8-12 weeks on site.
