What do bespoke & shaped rooflights in Llantwit Major involve?
For Llantwit Major homes and buildings we offer bespoke & shaped rooflights: triangular, angled, curved and multi-pane rooflights made to measure. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Wales sees a lot of wind-driven rain, particularly in the west, so upstand height and flashing laps matter more than anywhere. In Llantwit Major, as anywhere, bespoke & shaped rooflights are the usual choice for openings that standard sizes do not fit.
We work across South Glamorgan, including Llantwit Major, and in neighbouring towns such as Cowbridge and Bridgend. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Triangular and trapezoid panes
- Multi-pane butt-jointed runs
- Solar-control and low-iron glass
- Concealed or slim frames
- Corner and wrap-around glazing
- Drawing sign-off before order
- Works with architects and builders
What to check first
- Structural support must be designed in
- Longer lead times and no returns on made-to-measure glass
Planning and building rules for Llantwit Major
Welsh householder permitted development (Class C) allows rooflights that project no more than 15 cm and sit no higher than the existing roof — but not in conservation areas, National Parks, AONBs or World Heritage Sites. Listed buildings need listed building consent from the council, and flats have no householder permitted development rights.
In Wales the limiting values are 2.2 W/m²K for a rooflight and 1.4 W/m²K (or WER Band B) for a roof window in an existing house. Wales also has its own overheating rules (Part O) for new homes, in force since November 2022.

Bespoke & shaped rooflights in Llantwit Major: 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 bespoke units open?
Some can. Shaped glass is usually fixed, combined with a standard opening unit elsewhere.
Can you work alongside my builder in Llantwit Major?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Will I need planning permission in Llantwit Major?
In Wales a rooflight on a house is usually permitted development if it stands no more than 15 cm proud of the roof, except on protected land such as conservation areas and National Parks, where permission is needed.
