Glass links & glass box roofs for Thatcham: the essentials
Glass links & glass box roofs in Thatcham means frameless glass links joining old and new buildings. We cover the RG18 district and the rest of Berkshire, with a survey before any price is fixed.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. Typical uses for glass links & glass box roofs include listed and period buildings where the old wall should stay visible.
We work across Berkshire, including Thatcham, and in neighbouring towns such as Newbury and Basingstoke. Access, parking and how the glass reaches the roof are all checked at the survey.

Consents for glass links & glass box roofs in Thatcham
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. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
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.
Read the planning permission guide before you commit to a design.

Glass links & glass box roofs in Thatcham: questions
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.
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.
Do glass links need planning permission?
Often, yes — and listed building consent if either building is listed. We can provide drawings and product data for your application.
Will I need planning permission in Thatcham?
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.
