Frameless structural rooflights in Machynlleth: what is involved?
Our frameless structural rooflights service in Machynlleth covers minimal glass rooflights with no visible frame from inside. 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. Frameless structural rooflights suit architect-led extensions and long slots of light over islands or along party walls.
Neighbouring towns include Dolgellau (17 km) and Aberystwyth (25 km). We offer a survey date when we reply to your enquiry.
What you can choose
- Low-iron extra-clear glass
- Solar-control coatings
- Shadow-gap or plastered reveal
- Heated glass on some ranges
- Butt-jointed runs for long openings
- Clean modern detail for architect-led schemes
- Nothing but glass visible from inside
Before you order: points to check
- Large panes need lifting gear and access planning
- The internal finish (plaster, shadow gap) is agreed before order
Do you need permission in Machynlleth?
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.
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.
Read the planning permission guide before you commit to a design.

Frameless structural rooflights in Machynlleth: questions
Can it open?
Some frameless designs include a sliding or hinged opening element, but most are fixed. Pair with an opening unit if you need ventilation.
Does it cost more?
Usually, because the glass is larger and heavier and the finish needs tighter tolerances. The price table shows typical ranges.
How is it lifted onto the roof?
Larger panes go up with a vacuum lifter, a hoist or a crane. We plan access at survey.
Do I need to be at home for the survey in Machynlleth?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
How do I book a survey in Machynlleth?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
