Glass links & glass box roofs for Henley-on-Thames: the essentials
We handle glass links & glass box roofs across Oxfordshire, including Henley-on-Thames. In short: frameless glass links joining old and new buildings. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
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.
Henley-on-Thames is around 35 km from Oxford, and we survey and fit throughout that part of Oxfordshire, including the RG9 district.

Consents for glass links & glass box roofs in Henley-on-Thames
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. 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.
