Do I need planning permission in Newcastle-under-Lyme?
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.
The planning position for a specific Newcastle-under-Lyme 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).
Covering Newcastle-under-Lyme
Our survey diary covers Newcastle-under-Lyme, including ST1, ST2, ST4, ST5, ST6, ST12. Nearby, we also take on projects in Stoke-on-Trent (2 miles), Longton (4 miles), Kidsgrove (6 miles), Leek (11 miles).
Crewe, in Cheshire, is roughly 11 miles from Newcastle-under-Lyme and also on our list. Across the West Midlands, brick-built semis with long gardens are common, so single-storey and two-storey rear extensions are popular choices.
What is included
- Planning route checked or application made
- New openings through the side wall
- Windows, doors and finishes to match
- Structure, roof tied into the house
- Survey, design and street-view drawings
- Foundations near boundaries and any drains
Councils often prefer side extensions to sit slightly back from the front of the house with a lower roof, so the original building still reads clearly. We design to those principles from the start to avoid redesigns.
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.
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
Drawings are prepared and agreed with you, then submitted for the right planning route and building regulations approval.
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.
Questions people ask about side extensions
How long does a side extension take to build in Newcastle-under-Lyme?
On site, typically 10 to 18 weeks once approvals are in place. Before that, allow 6–14 weeks design and approvals.
Do you cover all of Newcastle-under-Lyme?
Yes. We cover Newcastle-under-Lyme and the surrounding parts of Staffordshire. Site visits are free and there is no obligation.
Who do I contract with for a side extension in Newcastle-under-Lyme?
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.
How close to the boundary can I build?
It depends on height. In England, within 2 m of a boundary the eaves must not exceed 3 m under permitted development. Building on the boundary is possible but brings party wall and maintenance access issues we plan for.
Can I build over my driveway?
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.
