What do glass links & glass box roofs in Flitwick involve?
For Flitwick 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.
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. In Flitwick, as anywhere, glass links & glass box roofs are the usual choice for listed and period buildings where the old wall should stay visible.
Flitwick sits about 3 km from Ampthill and 13 km from Dunstable, and we cover the whole MK45 postcode district and the roads in between.
Specification options
- Solar-control and low-iron glass
- Structural glass beams and fins
- Heated glass on some systems
- Frameless or slim-framed glass
- Concealed gutters and drainage
- Structural glass roof with concealed fixings
- Designed around the existing building
Things we check at survey
- Abutments with old masonry need careful weathering
- Thermal performance of large glass areas must be calculated
Consents for glass links & glass box roofs in Flitwick
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. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.

Questions about glass links & glass box roofs in Flitwick
How long does a link take?
Design and manufacture are the long part. Fitting is often two to five days.
How is the glass joined to the old wall?
Usually by a slim channel or flashing set into the masonry, sealed and weathered so the old wall can move without cracking the glass seal.
Who designs it?
Your architect, or we produce a survey-based design that the glass manufacturer engineers.
Will I need planning permission in Flitwick?
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line.
How do I book a survey in Flitwick?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
