Side return extensions in Worcestershire
Infilling the narrow passage beside a Victorian or Edwardian back addition. We design and build rear extensions across Worcestershire, from Worcester and Redditch to Kidderminster, covering single-storey kitchen extensions, two-storey additions, side returns and wraparounds.

Side return projects in Worcester usually start with a drainage survey of the side passage. Red-brick terraces and 1930s semis make up much of Worcestershire. Many already have a small kitchen lean-to at the back, which a new rear extension usually replaces rather than adds to.
How much does a side return extension cost in Worcestershire?
In Worcestershire, our guide for a side return extension is £2,300–£3,800 per square metre including VAT for a standard specification. The West Midlands is the baseline for our guide prices.
| Size | Guide price inc VAT |
|---|---|
| 2 m wide × 6 m deep (12 m²) | £27,500–£45,500 |
| 2.5 m wide × 7 m deep (17.5 m²) | £40,500–£66,500 |
These are guide ranges; the written quote after the survey is the figure that counts.
Do you need planning permission in Worcestershire?
Side return infills and the side leg of a wraparound are treated as side extensions in England: single-storey, no more than 4 metres high and no wider than half the original house. They are not permitted development in conservation areas, National Parks or National Landscapes, and a joined wraparound often needs a planning application because the side and rear rules apply together.
The Party Wall etc. Act 1996 applies in England: you serve notice two months before work to a shared wall, and one month before digging foundations within 3 metres (or 6 metres for deeper foundations) of a neighbour's building. Neighbours can agree in writing; if they dissent, surveyors agree an award.
Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent.

FAQ
Questions people ask
How much space does a side return add?
Typically 8 to 18 square metres, enough to turn a galley kitchen into a kitchen-diner with an island.
Do I need my neighbour's permission?
Not their permission, but in England and Wales you must serve party wall notices, and a neighbour can consent in writing or ask for a surveyor's award.
Can I combine a side return with a rear extension?
Yes; that is a wraparound extension, and it gives the biggest open-plan room a terrace can have.
Do you cover all of Worcestershire?
We cover 8 towns and districts in Worcestershire, including Worcester, Redditch and Kidderminster.
