Do you need planning permission for a terraced house rear extension in Kempston Hardwick?
Planning for a terraced house rear extension in Kempston Hardwick follows the English householder rules.
English permitted development (Class A) allows a single-storey rear extension of 3 metres on a terraced or semi-detached house and 4 metres on a detached one, measured from the original house, with a maximum height of 4 metres and eaves of no more than 3 metres 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 Kempston Hardwick like to extend?
Post-war semis and newer estates are typical of Kempston Hardwick, 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.

Terraced house rear extension questions in Kempston Hardwick
Can I live at home while the extension is built?

How do you keep the house clean?
Dust screens, floor protection and a single protected route through the house.
