Glass links & glass box roofs in Plymouth: what is involved?
For Plymouth 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.
Holiday lets and second homes across the South West often want roof windows with blinds and remote opening for when the house is empty. In Plymouth, as anywhere, glass links & glass box roofs are the usual choice for joining a period house to a new extension or annexe.
Plymouth is the main town we list in Devon; we also cover nearby Plymstock and Paignton.

Planning, building control and Plymouth
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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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.

Questions about glass links & glass box roofs in Plymouth
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.
