Glass links & glass box roofs in Oxford: what is involved?
Glass links & glass box roofs in Oxford means frameless glass links joining old and new buildings. We cover the OX1 district and the rest of Oxfordshire, with a survey before any price is fixed.
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. Typical uses for glass links & glass box roofs include listed and period buildings where the old wall should stay visible.
Oxford is the main town we list in Oxfordshire; we also cover nearby Abingdon and Didcot.

Do you need permission in Oxford?
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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
See our building regulations guide for U-values, glazing limits and self-certification.

Glass links & glass box roofs in Oxford: questions
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.
How long does a link take?
Design and manufacture are the long part. Fitting is often two to five days.
Is structural glass safe?
Structural glass is laminated so it stays in place if a ply breaks. The manufacturer designs it for the loads involved.
Can you work alongside my builder in Oxford?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do I need to be at home for the survey in Oxford?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
