Extensions in and around Newcastle-under-Lyme
Site visits are available across Newcastle-under-Lyme (ST1, ST2, ST4, ST5, ST6, ST12). The same team covers Stoke-on-Trent (2 miles), Longton (4 miles), Kidsgrove (6 miles), Leek (11 miles), all within easy reach.
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 we take care of
- Kitchen-ready shell or full finish
- Removal of the side wall and new steelwork
- Party wall notice support (England and Wales)
- Survey of the outrigger, boundary wall and drainage
- Glazed, sloping or flat roof with rooflights
Light is the design problem. A side return can make the middle of the house darker if the roof is solid, so we model the daylight and usually recommend a glazed slope or a run of rooflights along the boundary edge.

Planning rules that apply in Newcastle-under-Lyme
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 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).

Side return extension questions answered
Will my neighbours in Newcastle-under-Lyme 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.
How long does a side return extension take to build in Newcastle-under-Lyme?
On site, typically 10 to 14 weeks once approvals are in place. Before that, allow 6–12 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.
Will the kitchen be darker?
Not if the roof is designed well. A glazed roof or a line of rooflights along the boundary usually makes the room brighter than before.
How much does a side return extension cost?
Our guide range is about £2,040 to £3,690 per m² including VAT, so a typical 2 m × 5.5 m infill lands around £25,500 to £32,500 at standard spec in Newcastle-under-Lyme, more in London.
