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

Here is how the rules in England apply to a terraced house rear extension in Codicote.

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 Codicote like to extend?

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

How a terraced house rear extension in Codicote comes together

  1. Survey visit

    We visit free of charge, measure up, check access, drainage and neighbours' extensions, and note what you want the room to do.

  2. Options and costs

    We draw layout options and price each one, so the budget shapes the design rather than surprising you later.

  3. Planning and regulations

    We take the design through the right planning route, then produce the construction drawings and engineer's calculations for building control.

  4. Fixed price and build

    A written price for the agreed design, a start date and a named contact through the build, ending with the building control completion certificate.

FAQ

Terraced house rear extension questions in Codicote

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.

Is the site visit in Codicote free?

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

Can a terrace have a two-storey rear extension?

It is possible but harder to get through planning because of the effect on both neighbours.

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.

What postcode areas do you cover around Codicote?

Including AL6, AL8 and SG3, and the surrounding Hertfordshire area.

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

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