How we approach roof lanterns in Machynlleth
Roof lanterns in Machynlleth means hipped glass lanterns that lift the ceiling of orangeries and extensions. We cover the SY20 district and the rest of Powys, with a survey before any price is fixed.
Chapels, barns and farm buildings converted across Wales often need bespoke or conservation-style glass. Roof lanterns suit rooms that need height as well as light.
Machynlleth is around 38 km from Newtown, and we survey and fit throughout that part of Powys, including the SY20 district.
Specification options

- Internal and external colours

Things we check at survey
- Some designs project above the roof enough to affect planning on certain houses
- Plaster-box depth affects how the lantern looks from below
Planning and building rules for Machynlleth
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. Wales also has its own overheating rules (Part O) for new homes, in force since November 2022.
Read the planning permission guide before you commit to a design.

Roof lanterns in Machynlleth: questions
Do roof lanterns get hot?
They can in summer if clear glass is used on a south-facing roof. Solar-control glass and an opening vent make a big difference.
Aluminium or uPVC?
Aluminium gives slimmer bars and a longer life; uPVC costs less. We fit both.
Do they leak?
Modern lanterns are sealed systems. Leaks usually trace back to the kerb or roof membrane detail, which we form and check ourselves.

Yes. We survey and fit roof lanterns in Machynlleth and across Powys. Send your postcode and we will offer a survey date when we reply.
