What do glass links & glass box roofs in Chesham involve?
For Chesham 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.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. Typical uses for glass links & glass box roofs include listed and period buildings where the old wall should stay visible.
Chesham sits about 4 km from Amersham and 7 km from Berkhamsted, and we cover the whole HP5 postcode district and the roads in between.
Specification options
- Concealed gutters and drainage
- Frameless sliding or pivot doors
- Structural glass beams and fins
- Frameless or slim-framed glass
- Heated glass on some systems
- Visually light connection between buildings
- Keeps period walls on show
Before you order: points to check
- Structural calculations are part of the design
- Listed building consent or planning permission is commonly needed
Planning and building rules for Chesham
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. 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.
