Side return extensions in Rugby: design, approvals and build
We design and build side return extensions for houses in Rugby, with a written price once the survey and design are done and one point of contact throughout.

What is included
- Removal of the side wall and new steelwork
- Glazed, sloping or flat roof with rooflights
- Design to keep daylight in the middle of the house
- Kitchen-ready shell or full finish
- New boundary wall or raised party wall
- Party wall notice support (England and Wales)
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.
Do I need planning permission in Rugby?
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 Rugby address depends on its history and any designations, which is why we check it at the first visit.
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).
Local to Rugby
Our survey diary covers Rugby, including CV21, CV22, CV23. The same team covers Bedworth (11 miles), Leamington Spa (12 miles), Nuneaton (14 miles), Kenilworth (14 miles), all within easy reach.
Daventry, in Northamptonshire, is roughly 9 miles from Rugby 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.

Our process, step by step
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
We draw the design, agree it with you and handle planning or permitted development checks and building regulations.
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
Our team builds the extension, keeps you updated weekly and finishes with building control sign-off.
Side return extension questions answered
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Rugby, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Do I need building regulations approval in Rugby?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
Will my neighbours in Rugby 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 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 Rugby, more in London.
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.
