Like much of Cornwall, St Austell features granite cottages and coastal homes where marine-grade aluminium and storm-rated glazing are essential specs. 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 St Austell, Camborne, Bodmin and St Ives and every corner of Cornwall. Surveys and quotes are free, with a response within 1 working hour on every enquiry.
Standard sizes below — made to measure quoted same day. Installation available nationwide if you’d rather we fit it.

A footprint around one-fifth to one-quarter of the room area is the sweet spot. For a common 4m × 6m extension that points to roughly 1500 × 3000 — dramatic light without turning summer lunchtimes tropical.
Solar-control self-clean units — the coating manages summer heat gain and the self-clean layer deals with the film cooking puts on overhead glass. It's our default spec for kitchen projects.
It needs to — ducting routes across the flat-roof void are the most common clash. Send the kitchen plan and we'll position the lantern and kerb clear of the duct run before anything is ordered.
Once the slab is in and dimensions are real. Fabrication then runs while walls go up, and the lantern lands the week your roofer has the kerb ready — no site storage, no programme gap.
Yes — St Austell is inside our standard Cornwall coverage. Our fitting teams survey and install throughout the area, and supply-only deliveries run to St Austell on dedicated glass transport.
