Bespoke & shaped rooflights in St Austell: what is involved?
Our bespoke & shaped rooflights service in St Austell covers triangular, angled, curved and multi-pane rooflights made to measure. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
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 angled ceilings, corners and architect-designed extensions.
From St Austell to Bodmin, Truro and Newquay, the same survey-first process applies: measure, specify, fix the price, then fit.

Planning and building rules for St Austell
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. 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. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
Read the planning permission guide before you commit to a design.

Common questions
Will a shaped rooflight leak more?
Not if detailed properly — corners and junctions just need more care.
Can I cancel a bespoke order?
Made-to-measure goods are excluded from the statutory 14-day cancellation right. As a goodwill gesture you can cancel without charge until we place the order with the manufacturer, and we tell you in writing when that happens.
Can any shape be made?
Most straight-edged shapes can be made in glass, within the manufacturer's size and angle limits. Curved glass is possible but specialist.
Do I need to be at home for the survey in St Austell?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
