From Dorchester kitchen extensions to full orangery builds, our atlas roof lanterns service covers supply-only delivery and complete installation throughout Dorset — same product, your choice of who fits it.
Free, no-obligation quotes · response within 1 working hour · supply-only or fully installed
Like much of Dorset, Dorchester features coastal villas, thatched villages and retirement bungalows — light-filled garden rooms are a major driver. It's the kind of work our surveyors and fitting teams handle week in, week out across the South West region.
You get the same product either way — thermally broken aluminium, self-clean and solar-control glass options, made to the millimetre. The only choice is who fits it: your builder with our documentation, or our own nationwide teams.
Coverage takes in Dorchester, Blandford Forum, Bridport and Swanage and every corner of Dorset. Surveys and quotes are free, with a response within 1 working hour on every enquiry.
Anything from roughly 750mm × 750mm up past 6 metres in length. Every lantern is fabricated to your exact external kerb dimensions rather than forced to a stock size.
Yes — supply-only Atlas orders ship UK-wide with full fitting documentation, and installed projects are handled end to end by our own teams.
The external ridge sightline is 40mm and the hips match it — to put that in context, some budget systems run double that. From inside the room the bars all but vanish against the sky.
Atlas works from a 20-degree pitch, lower than most competing systems. That keeps the lantern's overall height down, which helps with proportion on single-storey extensions and with permitted-development height limits.
Yes — installation is available across Dorchester and Dorset, and if you'd rather buy supply-only, kerbside delivery to Dorchester is included in our standard service.
Standard-size supply-only prices are on the site now; made-to-measure quotes for Dorchester usually come back the same working day, and installed projects are priced after a free survey.
Send the form and we’ll come back with honest prices — supply-only or installed — with a response within 1 working hour.
