Glass links & glass box roofs in Dorchester: what is involved?
Our glass links & glass box roofs service in Dorchester 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.
Western coasts take wind-driven rain, so we pay close attention to upstand height and flashing laps on exposed roofs. Glass links & glass box roofs suit listed and period buildings where the old wall should stay visible.
Dorchester sits about 12 km from Weymouth and 23 km from Bridport, and we cover the whole DT1 postcode district and the roads in between.

Consents for glass links & glass box roofs in Dorchester
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.
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. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.
Read the planning permission guide before you commit to a design.

Common questions
How long does a link take?
Design and manufacture are the long part. Fitting is often two to five days.
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.
Do I need to be at home for the survey in Dorchester?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
