How we approach bespoke & shaped rooflights in Cowes
For Cowes 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.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. Bespoke & shaped rooflights suit angled ceilings, corners and architect-designed extensions.
Cowes sits about 7 km from Newport, Isle of Wight and 10 km from Ryde, and we cover the whole PO31 postcode district and the roads in between.

Planning, building control and Cowes
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. 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.

Bespoke & shaped rooflights in Cowes: questions
Do you need my architect's drawings?
They help. We still survey on site, because built openings rarely match drawings exactly.
Will a shaped rooflight leak more?
Not if detailed properly — corners and junctions just need more care.
Can I cancel a bespoke order?
Made-to-measure goods are excluded from the statutory 14-day cancellation right. As a goodwill gesture you can cancel without charge until we place the order with the manufacturer, and we tell you in writing when that happens.
Will I need planning permission in Cowes?
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.
