Single-storey rear extension in Buckhurst Hill

We plan and build single-storey rear extensions for homeowners in Buckhurst Hill. Ground-floor space across the back of the house, usually for a kitchen, dining or family room. Start with a free site visit, then a written price once the design is agreed.

We cover Buckhurst Hill (IG7, IG9 and IG10) as part of our Essex work. A depth of 3 to 4 metres keeps many single-storey rear extensions in Buckhurst Hill within permitted development, subject to the house's planning history.

Do you need planning permission for a single-storey rear extension in Buckhurst Hill?

Here is how the rules in England apply to a single-storey rear extension in Buckhurst Hill.

Under England's householder permitted development rules you can usually add 3 metres at the back of an attached house, or 4 metres on a detached house, without a planning application, as long as the extension stays under 4 metres high and its eaves stay under 3 metres where it is within 2 metres of a boundary.

If 3 or 4 metres is not enough, England's prior approval route allows 6 metres on a terraced or semi-detached house and 8 metres on a detached house for a single-storey rear extension. Neighbours are consulted, the council decides within 42 days, and the fee is £249, rising to £310 from 8 December 2026.

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 Buckhurst Hill like to extend?

Buckhurst Hill mixes Victorian terraces with 1930s semis, so both side returns and full-width kitchen extensions suit houses here.

How a single-storey rear extension in Buckhurst Hill comes together

  1. Look round and measure

    A free visit to see the back of the house, measure it, check the drains and boundaries and hear what you need.

  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

Single-storey rear extension questions in Buckhurst Hill

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.

Is the site visit in Buckhurst Hill free?

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

Will the extension make the room behind it dark?

Not if it is designed well. Rooflights or a lantern over the old back room, and a wide opening into it, keep daylight reaching the middle of the house.

Do you handle building control in Buckhurst Hill?

Yes. We apply to the council or a registered building control approver and hand over the completion certificate.

Who will build my extension?

Vetted building teams working under contract to us. Your contract is with S&K Property Investments and Improvement Ltd for the design and the build.

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.
