Glass links & glass box roofs in Chalfont St Peter: what is involved?
Our glass links & glass box roofs service in Chalfont St Peter covers frameless glass links joining old and new buildings. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Glass links & glass box roofs suit joining a period house to a new extension or annexe.
Chalfont St Peter sits about 3 km from Gerrards Cross and 6 km from Rickmansworth, and we cover the whole SL9 postcode district and the roads in between.

Planning, building control and Chalfont St Peter
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.
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. 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.
Read the planning permission guide before you commit to a design.

Glass links & glass box roofs in Chalfont St Peter: 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.
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.
Is the survey in Chalfont St Peter 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 Chalfont St Peter?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
