Working in Fleetwood
Site visits are available across Fleetwood (FY7). The same team covers Thornton-Cleveleys (4 miles), Poulton-le-Fylde (6 miles), Blackpool (8 miles), Morecambe (12 miles), all within easy reach.
Barrow-in-Furness, in Cumbria, is roughly 16 miles from Fleetwood and also on our list. Across the North West, terraced houses with small rear yards suit compact rear and side return extensions, while suburban semis have room for more.

- Separate or shared heating and hot water
- Kitchenette, shower room and bedroom finish
Will the council need to approve it?
In England an annexe that stays part of the household and connects to the house is assessed as an extension, but its size usually takes it beyond permitted development, so a householder application describing the ancillary use is the normal route.
In a conservation area, national park, National Landscape, the Broads or a World Heritage Site the permitted development limits are tighter (no side or two-storey extensions without an application). Listed homes need listed building consent, and if permitted development rights have been removed, any extension needs an application.
If the work involves a shared wall, building on the boundary, or digging foundations within 3 m (sometimes 6 m) of a neighbour's building, the Party Wall etc. Act 1996 applies and notice must be served before work starts: two months for work to a party wall, one month for new walls on the boundary and for excavations.
Applications are decided by the local planning authority (your district, borough or unitary council).

It starts with a visit to your house to measure, check access and talk through ideas and budget.
Design and approvals
We produce the drawings and structural design, and manage the approvals so they are in place before work starts.
Fixed written price
The price is fixed in writing once the design is settled, with a clear programme and payment stages.
Build and sign-off
The build is managed from start to finish, inspected at each stage and signed off on completion.
Your questions about an annexe extension in Fleetwood
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Fleetwood, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Do you cover all of Fleetwood?
Yes. We cover Fleetwood and the surrounding parts of Lancashire. Site visits are free and there is no obligation.
How long does an annexe extension take to build in Fleetwood?
On site, typically 16 to 24 weeks once approvals are in place. Before that, allow 10–16 weeks design and approvals.
How much does an annexe extension cost?
Our guide range is about £1,900 to £3,610 per m² including VAT. A one-bedroom annexe of about 35 m² is typically £79,500 to £100,000 at standard spec in Fleetwood.
Will an annexe affect council tax?
It can. Some annexes are assessed separately for council tax, with discounts or exemptions in some cases when occupied by a relative. Check with the Valuation Office Agency (England and Wales), your local assessor (Scotland) or Land & Property Services (Northern Ireland).
