How we approach glass links & glass box roofs in Sunderland
We handle glass links & glass box roofs across Tyne and Wear, including Sunderland. In short: frameless glass links joining old and new buildings. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Coastal exposure along the North East means we look closely at frame finishes and seals. Think of glass links & glass box roofs for listed and period buildings where the old wall should stay visible.
Sunderland sits about 8 km from Seaham and 9 km from Washington, and we cover the whole SR1 postcode district and the roads in between.

Planning and building rules for Sunderland
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. 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.
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.
Read the planning permission guide before you commit to a design.

Questions about glass links & glass box roofs in Sunderland
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.
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.
Can you work alongside my builder in Sunderland?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do I need to be at home for the survey in Sunderland?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
