Side return extension in Gosforth
Infilling the narrow passage beside a Victorian or Edwardian back addition. We design, get the approvals for and build side return extensions in Gosforth and the surrounding area, with one contract from the first survey to building control sign-off.
We cover Gosforth (NE2, NE3 and NE7) as part of our Tyne and Wear work. Side returns suit the Victorian and Edwardian terraces found across parts of Tyne and Wear, where the kitchen sits in a narrow back addition.

How much does a side return extension cost in Gosforth?
For Gosforth we work from the North East England rate: £2,070–£3,420 per square metre of new floor, including VAT, standard specification. North East prices are among the lowest in our range; former mining ground is the main foundation variable.
| Size | Guide price inc VAT |
|---|---|
| 2 m wide × 6 m deep (12 m²) | £25,000–£41,000 |
| 2.5 m wide × 7 m deep (17.5 m²) | £36,000–£60,000 |
These are guide ranges; the written quote after the survey is the figure that counts.
Do you need planning permission for a side return extension in Gosforth?
Whether your side return extension in Gosforth needs a planning application depends on its size, your house and any local restrictions.
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. At the first visit we measure what is there now and tell you which route fits: permitted development, prior approval or a planning application.
What are homes in Gosforth like to extend?
Brick terraces, colliery houses and post-war semis make up much of Gosforth. Former mining areas often need a coal mining risk check before foundations are designed.
