Glass links & glass box roofs in Beckenham: what is involved?
Our glass links & glass box roofs service in Beckenham 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.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. In Beckenham, as anywhere, glass links & glass box roofs are the usual choice for listed and period buildings where the old wall should stay visible.
Jobs in Beckenham are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
What you can choose
- Structural glass beams and fins
- Concealed gutters and drainage
- Heated glass on some systems
- Solar-control and low-iron glass
- Frameless or slim-framed glass
- Structural glass roof with concealed fixings
- Keeps period walls on show
Things we check at survey

Planning, building control and Beckenham
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.
See our building regulations guide for U-values, glazing limits and self-certification.
