Glass links & glass box roofs in Feltham: what is involved?
Thinking about glass links & glass box roofs in Feltham? The short answer: frameless glass links joining old and new buildings. The longer answer depends on your roof, which is why we survey before we price.
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. In Feltham, as anywhere, glass links & glass box roofs are the usual choice for listed and period buildings where the old wall should stay visible.
Feltham sits about 3 km from Ashford, Surrey and 4 km from Hounslow, and we cover the whole TW13 postcode district and the roads in between.

Planning, building control and Feltham
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. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
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. 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 Feltham: questions
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 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.
How long does a link take?
Design and manufacture are the long part. Fitting is often two to five days.
Can you work alongside my builder in Feltham?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Is the survey in Feltham free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
