Terraced house rear extension in Haverhill
For homes in Haverhill, a terraced house rear extension is often the simplest way to gain space without moving. Rear and side return extensions for terraces, with access through the house and two neighbours. We take it from survey to completion certificate.
We cover Haverhill (CB9) as part of our Suffolk work. Terraced streets make up much of the housing in parts of Suffolk, and most rear extensions here go in without side access.

Do you need planning permission for a terraced house rear extension in Haverhill?
The planning route for a terraced house rear extension in Haverhill is set by England's householder rules and your council.
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. We check your house's planning history and any conservation area before drawing, so the route is clear before you spend on plans.
What are homes in Haverhill like to extend?
Haverhill mixes Victorian terraces with 1930s semis, so both side returns and full-width kitchen extensions suit houses here.

FAQ
Terraced house rear extension questions in Haverhill
Can I get a price without a visit?
Our online guide-price tool gives a range in a couple of minutes. A written price needs a survey.
Can you match the brick or stone on my Haverhill house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
How deep can I go on a terrace?
3 metres under permitted development in England, or up to 6 metres with prior approval outside designated land.
Do I need a party wall agreement?
In England, usually yes if the extension is on or near a shared boundary or the foundations are close to a neighbour's building. We serve the notices.
