Planning and approvals in Whitefield

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.

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.

Building regulations approval is separate from planning. In England you can use the council's building control team or a registered building control approver; a full plans application gets the drawings checked before work starts, and the inspector signs the work off with a completion certificate.

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).

Covering Whitefield

Our survey diary covers Whitefield, including M25, M26, M45. Neighbouring towns we cover include Radcliffe (1 mile), Prestwich (1 mile), Bury (3 miles), Swinton (4 miles).

Rawtenstall, in Lancashire, is roughly 10 miles from Whitefield 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.

Included in a typical project

  • Sound insulation to the adjoining rooms
  • Window and rooflight placement to avoid screen glare
  • Heating or cooling sized for the room
  • Data cabling and plenty of sockets
  • Layout for desk, storage and video calls

North-facing glass and rooflights give steadier light for screen work. Where the office faces south, we use deeper reveals or external shading to keep glare and heat down.

How the project works

Site visits are free and there is no obligation. Where drawings are needed, the design stage is priced in writing before it starts.

  1. Free site visit

    A designer visits, takes measurements and photos, and discusses layouts, budget and timing with you.

  2. Design and approvals

    Drawings are prepared and agreed with you, then submitted for the right planning route and building regulations approval.

  3. Fixed written price

    We confirm the build price in writing, based on the approved drawings and the finishes you have chosen.

  4. Build and sign-off

    Work is carried out to the agreed programme, inspected by building control and signed off at the end.

Your questions about a home office extension in Whitefield

Who do I contract with for a home office extension in Whitefield?

Your contract is with S&K Property Investments and Improvement Ltd, which designs and manages the project and the build teams who carry it out.

Do I need building regulations approval in Whitefield?

Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.

Can I see a price before committing to anything?

Yes. The guide prices on this page are adjusted for Whitefield, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.

How much does a home office extension cost?

Our guide range is about £1,760 to £3,230 per m² including VAT. An 11 m² standard-spec office is typically £22,000 to £28,500 in Whitefield.

Is an attached office better than a garden office?

An attached office shares the house heating and broadband, adds floor area to the home, and needs no garden path in the rain. A garden building can be cheaper and quicker but is a separate structure.
