Built for Dorchester homes

The Dorset market is defined by coastal villas, thatched villages and retirement bungalows — light-filled garden rooms are a major driver — and our Dorchester installs reflect that, with specifications matched to the property rather than pulled off a shelf.

Specification doesn't change with postcode: thermally broken frames, 28mm argon-filled glazing, marine-grade powder coating and a 10-year guarantee, whether you buy supply-only for your own builder or book our installation teams.

Our teams cover Dorchester alongside Sherborne, Blandford Forum and Bridport and the rest of Dorset — surveys are free, quotes carry no obligation, and we aim for a response within 1 working hour.

Bespoke Roof Lanterns in Dorchester — common questions

How much more does bespoke cost?

It depends entirely on what departs from standard. An off-centre ridge adds little; a 7-metre triple-hip lantern with acoustic glass is a different conversation. We price from drawings with no obligation.

What's the lead time on a bespoke lantern?

Allow 4–8 weeks from approved drawings, longer for unusual glass. We'll commit to a fabrication slot when you approve, so the lantern lands when your build needs it.

Can a bespoke lantern avoid a steel beam in my roof?

Often, yes — shifting the ridge or splitting one large lantern into two smaller ones around the structure is a common bespoke solution. Send the structural drawings and we'll propose options.

What counts as a bespoke roof lantern?

Anything outside a standard rectangular, centre-ridge design — unequal hips, off-centre ridges, three-sided lanterns against walls, linked twin lanterns, unusual pitches or glass specifications. If your drawing doesn't look like a catalogue picture, it's bespoke.

Can I book installation in Dorchester?

We do. Dorchester and the surrounding Dorset towns are core territory for both our installation teams and our supply-only delivery routes.

How quickly can you quote for a Dorchester project?

For Dorchester: same-day made-to-measure quotes, standard sizes delivering in around 7–10 working days, and installation slots booked to suit once the survey's done.
