Glass links & glass box roofs in Hampton: what is involved?
Glass links & glass box roofs in Hampton means frameless glass links joining old and new buildings. We cover the TW12 district and the rest of Greater London, with a survey before any price is fixed.
Party walls are a fact of life in London terraces, and rooflights close to a shared wall need detailing that keeps the neighbour's side dry too. Typical uses for glass links & glass box roofs include listed and period buildings where the old wall should stay visible.
From Hampton to Sunbury-on-Thames, Walton-on-Thames and Twickenham, the same survey-first process applies: measure, specify, fix the price, then fit.

Consents for glass links & glass box roofs in Hampton
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. 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.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
See our building regulations guide for U-values, glazing limits and self-certification.

Glass links & glass box roofs in Hampton: questions
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.
Who designs it?
Your architect, or we produce a survey-based design that the glass manufacturer engineers.
How is the glass joined to the old wall?
Usually by a slim channel or flashing set into the masonry, sealed and weathered so the old wall can move without cracking the glass seal.
Do I need to be at home for the survey in Hampton?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Can you work alongside my builder in Hampton?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
