Glass links & glass box roofs for Twickenham: the essentials
For Twickenham 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 listed and period buildings where the old wall should stay visible.
From Twickenham to Richmond, Kingston upon Thames and Hounslow, the same survey-first process applies: measure, specify, fix the price, then fit.

Planning and building rules for Twickenham
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. 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. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
See our building regulations guide for U-values, glazing limits and self-certification.

Glass links & glass box roofs in Twickenham: questions
How long does a link take?
Design and manufacture are the long part. Fitting is often two to five days.
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.
Do glass links need planning permission?
Often, yes — and listed building consent if either building is listed. We can provide drawings and product data for your application.
Is the survey in Twickenham free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Can you work alongside my builder in Twickenham?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
