What do glass links & glass box roofs in Leatherhead involve?
Thinking about glass links & glass box roofs in Leatherhead? 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.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. In Leatherhead, as anywhere, glass links & glass box roofs are the usual choice for joining a period house to a new extension or annexe.
Leatherhead is around 16 km from Woking, and we survey and fit throughout that part of Surrey, including the KT22 district.

Planning, building control and Leatherhead
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.
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.

Glass links & glass box roofs in Leatherhead: questions
Who designs it?
Your architect, or we produce a survey-based design that the glass manufacturer engineers.
Can a glass link be warm enough to use all year?
With insulated glass units, solar control and good detailing, yes — though it will always be brighter and more exposed to temperature swings than a solid room.
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.
Will I need planning permission in Leatherhead?
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.
Do I need to be at home for the survey in Leatherhead?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
