Planning rules that apply in Wakefield
In England a single-storey side extension can be permitted development if it is no more than 4 m high and no wider than half the width of the original house. Two-storey side extensions, and any side extension on designated land such as a conservation area, need a householder planning application.
Homes in conservation areas, national parks, National Landscapes (formerly AONBs), the Broads and World Heritage Sites have tighter rules, so we always check the property's status and planning history before design starts.
Building over or within 3 m of a public sewer needs the water company's consent, usually through a build-over agreement, before the foundations go in.
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).
What we take care of
- Structure, roof tied into the house
- New openings through the side wall
- Planning route checked or application made
- Foundations near boundaries and any drains
- Windows, doors and finishes to match

Covering Wakefield
Site visits are available across Wakefield (WF1, WF2, WF3, WF4, WF5, WF6). The same team covers Ossett (3 miles), Dewsbury (5 miles), Morley (6 miles), Batley (6 miles), all within easy reach.
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.
From first visit to completion
Site visits are free and there is no obligation. Where drawings are needed, the design stage is priced in writing before it starts.
Free site visit
First, a site visit: we look at the house, garden, access and drains and listen to what you need.
Design and approvals
Once the layout is agreed, we deal with the council: planning permission or written confirmation that none is needed, plus building control.
Fixed written price
We confirm the build price in writing, based on the approved drawings and the finishes you have chosen.
Build and sign-off
We build it with one project manager, book the building control inspections and hand over the completion certificate.

Do you cover all of Wakefield?

Yes, if the foundations work and you keep any parking the council requires. Drains and services under drives are common, so we check before design.
