Do you need planning permission for a terraced house rear extension in Billericay?

Planning for a terraced house rear extension in Billericay follows the English householder rules.

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.

Because rear extensions often sit on or near the boundary, the Party Wall etc. Act 1996 usually applies in England. Notices go out one or two months before work depending on the type of work, and a surveyor's award is only needed if a neighbour does not consent.

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 Billericay like to extend?

Post-war semis and newer estates are typical of Billericay, 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.

  1. Free site visit

    We measure the house and garden, look at the back wall, drainage and boundaries, and talk through what you want from the space.

  2. Options and costs

FAQ

Terraced house rear extension questions in Billericay

How long does a rear extension take to build in Billericay?

Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.

Can I live at home while the extension is built?

Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.

Do both neighbours need party wall notices?

Usually yes in England and Wales, because the extension often sits on or near both boundaries.

Is the site visit in Billericay free?

Yes. We visit, measure up and talk through the options with no cost and no obligation.

Do I need planning permission for a rear extension in Billericay?

Often not for a single-storey rear extension of up to 3 metres (4 metres on a detached house) under permitted development, or up to 6 or 8 metres with prior approval, unless the house is in a conservation area or its rights have been removed.

Can you match the brick or stone on my Billericay house?

We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
