Planning and approvals in Wakefield
In England an annexe that stays part of the household and connects to the house is assessed as an extension, but its size usually takes it beyond permitted development, so a householder application describing the ancillary use is the normal route.
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).
When an annexe extension makes sense

- Homes with a large side or rear garden
Local to Wakefield
We cover Wakefield and the postcode districts WF1, WF2, WF3, WF4, WF5, WF6. Nearby, we also take on projects in 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.

Common questions in Wakefield
Who do I contract with for an annexe 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.
Does an annexe extension need planning permission?
Usually yes, because of its size and the way it will be used. Councils check that it stays ancillary to the main house, so the application must describe the use clearly.
Will an annexe affect council tax?
It can. Some annexes are assessed separately for council tax, with discounts or exemptions in some cases when occupied by a relative. Check with the Valuation Office Agency (England and Wales), your local assessor (Scotland) or Land & Property Services (Northern Ireland).
