What do glass links & glass box roofs in Croydon involve?
For Croydon homes and buildings we offer glass links & glass box roofs: frameless glass links joining old and new buildings. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. Think of glass links & glass box roofs for joining a period house to a new extension or annexe.
We work across Greater London, including Croydon, and in neighbouring towns such as South Croydon and Wallington. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Frameless sliding or pivot doors
- Frameless or slim-framed glass
- Concealed gutters and drainage
- Heated glass on some systems
- Structural glass beams and fins
- Structural glass roof with concealed fixings
- Keeps period walls on show
Things we check at survey
- Thermal performance of large glass areas must be calculated
- Abutments with old masonry need careful weathering
Do you need permission in Croydon?
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.

Glass links & glass box roofs in Croydon: questions
Is structural glass safe?
Structural glass is laminated so it stays in place if a ply breaks. The manufacturer designs it for the loads involved.
Who designs it?
Your architect, or we produce a survey-based design that the glass manufacturer engineers.
Can a glass link be warm enough to use all year?
With insulated glass units, solar control and good detailing, yes — though it will always be brighter and more exposed to temperature swings than a solid room.
Do you fit glass links & glass box roofs in Croydon?
Yes. We survey and fit glass links & glass box roofs in Croydon and across Greater London. Send your postcode and we will offer a survey date when we reply.
Do I need to be at home for the survey in Croydon?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
