What do bespoke & shaped rooflights in Beckenham involve?
For Beckenham 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.
Party walls are a fact of life in London terraces, and rooflights close to a shared wall need detailing that keeps the neighbour's side dry too. Typical uses for bespoke & shaped rooflights include angled ceilings, corners and architect-designed extensions.
Neighbouring towns include Bromley (3 km) and Catford (4 km). We offer a survey date when we reply to your enquiry.

Planning, building control and Beckenham
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. 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.
Read the planning permission guide before you commit to a design.

Questions about bespoke & shaped rooflights in Beckenham
Can any shape be made?
Most straight-edged shapes can be made in glass, within the manufacturer's size and angle limits. Curved glass is possible but specialist.
Why does bespoke take longer?
Each unit is drawn, checked and manufactured to order.
Can bespoke units open?
Some can. Shaped glass is usually fixed, combined with a standard opening unit elsewhere.

Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Can you work alongside my builder in Beckenham?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
