Extensions in and around Thornton-Cleveleys
We cover Thornton-Cleveleys and the postcode districts FY2, FY5, FY6. Nearby, we also take on projects in Poulton-le-Fylde (3 miles), Fleetwood (4 miles), Blackpool (4 miles), Lytham St Annes (9 miles).
Southport, in Merseyside, is roughly 16 miles from Thornton-Cleveleys and also on our list. The North West has a high share of Victorian and Edwardian terraces with rear yards and outriggers, plus large areas of inter-war semis in the suburbs.
Will the council need to approve it?
In England a single-storey rear extension can usually go up to 3 m beyond the original rear wall of a semi-detached or terraced house, or 4 m on a detached house, without a planning application, provided it is no more than 4 m high, keeps eaves to 3 m within 2 m of a boundary and, with other buildings, covers no more than half the land around the original house. The larger home extension prior approval scheme raises those depths to 6 m and 8 m, with neighbours notified and a 42-day decision.
The planning position for a specific Thornton-Cleveleys address depends on its history and any designations, which is why we check it at the first visit.
Building over or within 3 m of a public sewer needs the water company's consent, usually through a build-over agreement, before the foundations go in.
Applications are decided by the local planning authority (your district, borough or unitary council).

Your questions about a utility room extension in Thornton-Cleveleys
Do I need building regulations approval in Thornton-Cleveleys?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
Will my neighbours in Thornton-Cleveleys be involved?
If a planning application or prior approval is needed, the council notifies neighbours. If the work is on or near a shared boundary, party wall notices may also be needed.
Do you cover all of Thornton-Cleveleys?
Yes. We cover Thornton-Cleveleys and the surrounding parts of Lancashire. Site visits are free and there is no obligation.
Can a utility have a toilet?
Yes, space permitting. A WC needs drainage and extraction, which we plan into the design.
Does a utility extension need planning permission?
Often not, if it is single storey and within permitted development limits. We check this for your property.
