Will the council need to approve it?
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.
The planning position for a specific Wakefield address depends on its history and any designations, which is why we check it at the first visit.
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).
Working in Wakefield
Postcode districts we cover around Wakefield include WF1, WF2, WF3, WF4, WF5, WF6. We also work in nearby Ossett (3 miles), Dewsbury (5 miles), Morley (6 miles), Batley (6 miles).
Just over the South Yorkshire border, Darton is about 7 miles away. 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.
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.

Design and approvals
We produce the drawings and structural design, and manage the approvals so they are in place before work starts.

With the design and specification agreed, you get a fixed written price and a start date.
Build and sign-off
We build it with one project manager, book the building control inspections and hand over the completion certificate.
Questions people ask about side return extensions
Who do I contract with for a side return extension in Wakefield?
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 you cover all of Wakefield?
Yes. We cover Wakefield and the surrounding parts of West Yorkshire. Site visits are free and there is no obligation.
Will my neighbours in Wakefield 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 side return extensions need planning permission?
In England many single-storey side returns fit within permitted development if they stay within the height limits and are no wider than half the width of the original house. Conservation areas, listed buildings and flats need an application. Other UK nations have their own rules, which we check.
How much does a side return extension cost?
Our guide range is about £1,970 to £3,570 per m² including VAT, so a typical 2 m × 5.5 m infill lands around £24,500 to £31,500 at standard spec in Wakefield, more in London.
