What should I budget for a side return extension in Shrewsbury?
Labour and material costs vary across the UK, so for Shrewsbury we use our West Midlands factor (×0.97). The ranges include VAT and exclude design, structural and council fees.
Typical rates in Shrewsbury: £2,040 to £3,690 per m² including VAT, depending on specification.

Working in Shrewsbury
Site visits are available across Shrewsbury (SY1, SY2, SY3). We also work in nearby Wellington (10 miles), Telford (13 miles), Oswestry (16 miles), Market Drayton (18 miles).
Just over the Staffordshire border, Stafford is about 27 miles away. The West Midlands has a large stock of 1930s and post-war semi-detached houses, which are well suited to rear, side and over-garage extensions, plus Victorian terraces in the older inner areas.
Planning and approvals in Shrewsbury
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 Shrewsbury 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).
What we take care of
- Glazed, sloping or flat roof with rooflights
- Design to keep daylight in the middle of the house
- Removal of the side wall and new steelwork
- Party wall notice support (England and Wales)
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
A designer visits, takes measurements and photos, and discusses layouts, budget and timing with you.
Design and approvals
Drawings are prepared and agreed with you, then submitted for the right planning route and building regulations approval.
Fixed written price
The price is fixed in writing once the design is settled, with a clear programme and payment stages.
Build and sign-off
Work is carried out to the agreed programme, inspected by building control and signed off at the end.
Common questions in Shrewsbury
Do you cover all of Shrewsbury?
Yes. We cover Shrewsbury and the surrounding parts of Shropshire. Site visits are free and there is no obligation.
Do I need building regulations approval in Shrewsbury?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
How long does a side return extension take to build in Shrewsbury?
On site, typically 10 to 14 weeks once approvals are in place. Before that, allow 6–12 weeks design and approvals.
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.
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.
