Bespoke & shaped rooflights in Dolgellau: what is involved?
We handle bespoke & shaped rooflights across Gwynedd, including Dolgellau. In short: triangular, angled, curved and multi-pane rooflights made to measure. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Welsh planning rules exclude rooflights from permitted development in conservation areas and National Parks, so we check the designation before quoting. In Dolgellau, as anywhere, bespoke & shaped rooflights are the usual choice for openings that standard sizes do not fit.
From Dolgellau to Machynlleth, Porthmadog and Aberystwyth, the same survey-first process applies: measure, specify, fix the price, then fit.

- Solar-control and low-iron glass

Before you order: points to check

Planning and building rules for Dolgellau
Planning rules in Wales are tighter than in England for rooflights: Class C rights do not apply in conservation areas, National Parks or AONBs, so a rooflight there needs planning permission. A side-facing rooflight within 10.5 m of the boundary must be obscure-glazed, and non-opening unless the opening part is more than 1.7 m above the floor.
Welsh Building Regulations expect new or replacement rooflights to reach 2.2 W/m²K and roof windows 1.4 W/m²K or a Band B rating. A revised Welsh Approved Document L takes effect on 4 March 2027; rooflights in new dwellings stay at 2.2 W/m²K.
See our building regulations guide for U-values, glazing limits and self-certification.

Bespoke & shaped rooflights in Dolgellau: questions
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.
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.
Can you work alongside my builder in Dolgellau?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
