How we approach frameless structural rooflights in Richmond
Thinking about frameless structural rooflights in Richmond? The short answer: minimal glass rooflights with no visible frame from inside. The longer answer depends on your roof, which is why we survey before we price.
Victorian and Edwardian terraces with narrow side returns are typical of much of London, and a glass roof or long flat rooflight is the usual way to keep the back rooms bright once the return is built over. Think of frameless structural rooflights for architect-led extensions and long slots of light over islands or along party walls.
Jobs in Richmond 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.
Choices for your Richmond project
- Solar-control coatings
- Low-iron extra-clear glass
- Heated glass on some ranges
- Shadow-gap or plastered reveal
- Triple glazing
- Double or triple glazed structural units
- Clean modern detail for architect-led schemes
What to check first
- The internal finish (plaster, shadow gap) is agreed before order
- Tolerances are tight — the opening must be built square and to size
Planning and building rules for Richmond
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. 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. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.

More we do in Richmond
Frameless structural rooflights in Richmond: 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.
Can a frameless rooflight be walked on?
Only if it is specified as a walk-on unit. Most frameless rooflights are for light only.
Will I see the edge of the glass?
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.
Will I need planning permission in Richmond?
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.
Do I need to be at home for the survey in Richmond?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
