Covering Preston
Our survey diary covers Preston, including PR1, PR2, PR4, PR5, PR25, PR26. Neighbouring towns we cover include Leyland (5 miles), Chorley (9 miles), Blackburn (9 miles), Darwen (11 miles).
Horwich, in Greater Manchester, is roughly 13 miles from Preston 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.
Planning and approvals in Preston
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 Preston address depends on its history and any designations, which is why we check it at the first visit.
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).

Your questions about a utility room extension in Preston
Will my neighbours in Preston 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 I need building regulations approval in Preston?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
Do you cover all of Preston?
Yes. We cover Preston and the surrounding parts of Lancashire. Site visits are free and there is no obligation.
How much does a utility room extension cost?
Our guide range is about £1,800 to £3,320 per m² including VAT, with a minimum of around £13,500. An 8 m² standard-spec utility is typically £17,000 to £21,500 in Preston.
Can a utility have a toilet?
Yes, space permitting. A WC needs drainage and extraction, which we plan into the design.
