Glass links & glass box roofs for Seaham: the essentials
Our glass links & glass box roofs service in Seaham covers frameless glass links joining old and new buildings. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
North East terraces and colliery-town housing often have rear offshoots where a rooflight brightens a narrow kitchen. In Seaham, as anywhere, glass links & glass box roofs are the usual choice for listed and period buildings where the old wall should stay visible.
Neighbouring towns include Houghton-le-Spring (8 km) and Sunderland (8 km). We offer a survey date when we reply to your enquiry.

Do you need permission in Seaham?
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. 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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about glass links & glass box roofs in Seaham
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.
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.
Is structural glass safe?
Structural glass is laminated so it stays in place if a ply breaks. The manufacturer designs it for the loads involved.
Do I need to be at home for the survey in Seaham?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Will I need planning permission in Seaham?
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.
