Glass links & glass box roofs for Towcester: the essentials
Thinking about glass links & glass box roofs in Towcester? The short answer: frameless glass links joining old and new buildings. The longer answer depends on your roof, which is why we survey before we price.
Many Midlands semis have had a single-storey rear extension added, and a larger flat rooflight or lantern is often the change that makes it feel finished. Glass links & glass box roofs suit joining a period house to a new extension or annexe.
We work across Northamptonshire, including Towcester, and in neighbouring towns such as Northampton and Daventry. Access, parking and how the glass reaches the roof are all checked at the survey.

Consents for glass links & glass box roofs in Towcester
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.
