How we approach frameless structural rooflights in Morden
For Morden homes and buildings we offer frameless structural rooflights: minimal glass rooflights with no visible frame from inside. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. In Morden, as anywhere, frameless structural rooflights are the usual choice for architect-led extensions and long slots of light over islands or along party walls.
Morden sits about 2 km from Mitcham and 3 km from Wimbledon, and we cover the whole SM4 postcode district and the roads in between.

Planning and building rules for Morden
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.

From inside, the reveal is finished up to the glass so the edge is hidden. From outside you will see the glass and its edge seal.
