Terraced house rear extension in Norwich
Rear and side return extensions for terraces, with access through the house and two neighbours. We design, get the approvals for and build rear extensions for terraced houses in Norwich and the surrounding area, with one contract from the first survey to building control sign-off.
Norwich and its postcode districts NR3, NR4, NR5 and NR6 are part of our Norfolk coverage. Terraced streets make up much of the housing in parts of Norfolk, and most rear extensions here go in without side access.

How much does a terraced house rear extension cost in Norwich?
For Norwich we work from the East of England rate: £2,170–£3,500 per square metre of new floor, including VAT, standard specification. East of England prices run slightly above our West Midlands baseline; clay soils near trees are the main foundation variable.

| 3 m wide × 6 m deep (18 m²) | £39,000–£63,000 |
These are guide ranges; the written quote after the survey is the figure that counts.
Do you need planning permission for a terraced house rear extension in Norwich?
Whether your terraced house rear extension in Norwich needs a planning application depends on its size, your house and any local restrictions.
In England a single-storey rear extension can often be built under permitted development: up to 3 metres beyond the original rear wall of an attached house, or 4 metres on a detached house, no higher than 4 metres, with eaves no higher than 3 metres if any part is within 2 metres of a boundary.
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 Norwich like to extend?
Post-war semis and newer estates are typical of Norwich, and many have room for a full-width extension. Shrinkable clay is common in the East of England, so foundations near trees and hedges are designed to NHBC-style depth guidance. In Norwich we plan the delivery route through the house and the skip licence before anything else.
