Covering Fleetwood
We work in Fleetwood (FY7) and the places around it, including Thornton-Cleveleys, Blackpool and Morecambe.
Homes in the North West
The North West has long rows of Victorian terraced houses in its towns and cities, alongside inter-war semis and post-war estates, so rear extensions, dormer lofts and kitchen extensions are common projects.
What do you get with a dormer loft conversion?
A dormer loft conversion builds a box-shaped extension out from the rear slope of the roof, creating vertical walls and full head height across most of the new floor. It is the most popular type of loft conversion because it gives the most usable space for the cost.
- Lawful development certificate or planning drawings
- Steelwork and new floor structure
- Staircase, insulation and plasterboard
How much should I budget for a dormer loft conversion?

| Full-width dormer with en-suite | £60,000 to £80,000 |

How is a dormer loft conversion approved in Fleetwood?
In England we deal with the council’s planning team for permission or a lawful development certificate, with building control (the council or a registered building control approver) for inspections, and with neighbours under the Party Wall etc. Act 1996 where it applies.
In England many loft conversions are permitted development: the extra roof volume must stay within 40 m³ on a terraced house or 50 m³ on a semi or detached house, nothing can sit higher than the existing ridge, no dormer can face a road on the main elevation, and side windows must be obscure-glazed and non-opening below 1.7 m.
What can affect a dormer loft conversion?
- Dormers on the front of the house facing a road are not permitted development in England.
- L-shaped dormers are common on Victorian terraces with a rear outrigger.
What happens after I enquire?
- Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
- We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
- Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
- Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.
