Bespoke & shaped rooflights in Dorchester: what is involved?
Bespoke & shaped rooflights in Dorchester means triangular, angled, curved and multi-pane rooflights made to measure. We cover the DT1 district and the rest of Dorset, with a survey before any price is fixed.
Barn and chapel conversions in the South West often need bespoke or shaped rooflights to suit the original structure. Think of bespoke & shaped rooflights for openings that standard sizes do not fit.
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.

Do you need permission 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.
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. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Bespoke & shaped rooflights in Dorchester: questions
Do you need my architect's drawings?
They help. We still survey on site, because built openings rarely match drawings exactly.
Can bespoke units open?
Some can. Shaped glass is usually fixed, combined with a standard opening unit elsewhere.
Why does bespoke take longer?
Each unit is drawn, checked and manufactured to order.
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.
Can you work alongside my builder in Dorchester?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
