Glass links & glass box roofs in Portslade: what is involved?
Our glass links & glass box roofs service in Portslade 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.
Larger gardens in much of the South East mean deeper rear extensions, and deeper rooms need light from above rather than only from the doors. Glass links & glass box roofs suit listed and period buildings where the old wall should stay visible.
From Portslade to Hove, Brighton and Worthing, the same survey-first process applies: measure, specify, fix the price, then fit.
Specification options
- Frameless sliding or pivot doors
- Structural glass beams and fins
- Frameless or slim-framed glass
- Solar-control and low-iron glass
- Heated glass on some systems
- Visually light connection between buildings

Things we check at survey
- Abutments with old masonry need careful weathering
- Structural calculations are part of the design
Consents for glass links & glass box roofs in Portslade
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.
