How we approach glass links & glass box roofs in Amersham
For Amersham 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.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. Think of glass links & glass box roofs for listed and period buildings where the old wall should stay visible.
From Amersham to Chesham, Chalfont St Peter and Gerrards Cross, the same survey-first process applies: measure, specify, fix the price, then fit.

Planning and building rules for Amersham
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.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. 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.
