Bespoke & shaped rooflights in Tottenham: what is involved?
Bespoke & shaped rooflights in Tottenham means triangular, angled, curved and multi-pane rooflights made to measure. We cover the N17 district and the rest of Greater London, with a survey before any price is fixed.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. Bespoke & shaped rooflights suit openings that standard sizes do not fit.
From Tottenham to Edmonton, Wood Green and Walthamstow, the same survey-first process applies: measure, specify, fix the price, then fit.

Do you need permission in Tottenham?
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. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Can bespoke units open?
Some can. Shaped glass is usually fixed, combined with a standard opening unit elsewhere.
Do you need my architect's drawings?
They help. We still survey on site, because built openings rarely match drawings exactly.
Why does bespoke take longer?
Each unit is drawn, checked and manufactured to order.
