Glass links & glass box roofs in Weymouth: what is involved?
Our glass links & glass box roofs service in Weymouth 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.
Many South West towns mix Georgian and Victorian terraces with modern estates, so the right product differs street by street. Glass links & glass box roofs suit listed and period buildings where the old wall should stay visible.
We work across Dorset, including Weymouth, and in neighbouring towns such as Dorchester and Bridport. Access, parking and how the glass reaches the roof are all checked at the survey.

Planning and building rules for Weymouth
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.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. 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.
Our planning guide covers each nation in more detail.

Glass links & glass box roofs in Weymouth: questions
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.
How long does a link take?
Design and manufacture are the long part. Fitting is often two to five days.
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.
Will I need planning permission in Weymouth?
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.
Can you work alongside my builder in Weymouth?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
