Bespoke & shaped rooflights for Porthmadog: the essentials
Our bespoke & shaped rooflights service in Porthmadog 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.
Chapels, barns and farm buildings converted across Wales often need bespoke or conservation-style glass. Think of bespoke & shaped rooflights for openings that standard sizes do not fit.
Jobs in Porthmadog are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.

Consents for bespoke & shaped rooflights in Porthmadog
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.
Approved Document L in Wales (2022 edition) sets 2.2 W/m²K for rooflights, measured horizontally, and 1.4 W/m²K or Band B for roof windows in existing homes. A revised Welsh Approved Document L takes effect on 4 March 2027; rooflights in new dwellings stay at 2.2 W/m²K.

Common questions
Why does bespoke take longer?
Each unit is drawn, checked and manufactured to order.
Do you need my architect's drawings?
They help. We still survey on site, because built openings rarely match drawings exactly.
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 you work alongside my builder in Porthmadog?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do you offer bespoke & shaped rooflights in Porthmadog?
Yes. We carry out bespoke & shaped rooflights in Porthmadog and across Gwynedd. Send your postcode and we will offer a survey date when we reply.
