Glazed rear extension in Fleetwood
For homes in Fleetwood, a glazed rear extension is often the simplest way to gain space without moving. Full-height glass, slim frames and big rooflights for the most open rear room. We take it from survey to completion certificate.
We cover Fleetwood (FY5 and FY7) as part of our Lancashire work. Glass-led rear extensions in Fleetwood are planned around which way the garden faces, because that decides the glass specification.

Do you need planning permission for a glazed rear extension in Fleetwood?
Planning for a glazed rear extension in Fleetwood follows the English householder rules.
Under England's householder permitted development rules you can usually add 3 metres at the back of an attached house, or 4 metres on a detached house, without a planning application, as long as the extension stays under 4 metres high and its eaves stay under 3 metres where it is within 2 metres of a boundary.
New fabric must meet Approved Document L (2021 edition incorporating 2023 amendments): walls 0.18, roof 0.15 and floor 0.18 W/m²K, windows 1.4 W/m²K or Band B. Under the simple route, new windows, doors and rooflights should not exceed 25% of the extension floor area plus any openings removed; more glass is possible with a whole-house calculation.
Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent. At the first visit we measure what is there now and tell you which route fits: permitted development, prior approval or a planning application.
What are homes in Fleetwood like to extend?
Stone and brick terraces are common around Fleetwood. Where houses back onto a ginnel or alley, deliveries can come in from the rear, which makes the build tidier. A wide sliding door with one long rooflight, rather than a fully glazed roof, keeps a glass-led extension usable in summer.
