Glass links & glass box roofs for Daventry: the essentials
Thinking about glass links & glass box roofs in Daventry? 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.
Daventry is around 19 km from Northampton, and we survey and fit throughout that part of Northamptonshire, including the NN11 district.

Do you need permission in Daventry?
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. 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.
Read the planning permission guide before you commit to a design.
