Glass links & glass box roofs in Cheltenham: what is involved?
For Cheltenham 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.
Barn and chapel conversions in the South West often need bespoke or shaped rooflights to suit the original structure. In Cheltenham, as anywhere, glass links & glass box roofs are the usual choice for joining a period house to a new extension or annexe.
We work across Gloucestershire, including Cheltenham, and in neighbouring towns such as Tewkesbury and Gloucester. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Concealed gutters and drainage
- Solar-control and low-iron glass
- Structural glass beams and fins
- Heated glass on some systems
- Frameless or slim-framed glass
- Can include frameless doors
- Keeps period walls on show
What to check first
- Structural calculations are part of the design
- Listed building consent or planning permission is commonly needed
Planning and building rules for Cheltenham
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. 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.
Our planning guide covers each nation in more detail.
