Planning and building control in Leeds
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 England a single-storey side return infill is often permitted development if it stays within the height limits and is no wider than half the width of the original house. Conservation areas, listed buildings and flats always need an application, and the boundary wall usually brings in the Party Wall Act.
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.
Applications are decided by the local planning authority (your district, borough or unitary council).
Covering Leeds and nearby
Our survey diary covers Leeds, including LS1, LS2, LS3, LS4, LS7, LS11. Nearby, we also take on projects in Morley (4 miles), Pudsey (5 miles), Horsforth (5 miles), Batley (7 miles), Yeadon (7 miles). Harrogate, in North Yorkshire, is roughly 13 miles from Leeds and also on our list.
Which extension suits a Leeds home?
Yorkshire and the Humber combines stone-built terraces in the Pennine towns with brick semis and newer estates elsewhere, so materials and roof details need matching with care.
The types we would usually look at first for a home in Leeds are pitched roof extensions, single-storey rear extensions and side return extensions, depending on the garden and how the house is laid out.

Questions about extensions in Leeds
How much does an extension cost in Leeds?
Using our Yorkshire and the Humber factor (×0.94), a standard-spec single-storey extension of 20 m² is a guide £38,500 to £49,000 including VAT, and a 32 m² two-storey extension £54,000 to £71,000. Your written price follows the survey.
Do I need planning permission for an extension in Leeds?
Not always. It depends on the size, position and your property's history. Many single-storey rear extensions in England are permitted development or can use prior approval.
Will my neighbours need to be told?
If you apply for planning or prior approval the council notifies them, and in England party wall notices may be needed for work near a shared boundary.
Do you handle building regulations?
Yes. We prepare the drawings and calculations, submit them and book inspections, ending with a completion certificate.
