Kitchen-diner rear extension in Reading

An open-plan kitchen, dining and family room that opens straight onto the garden. We design, get the approvals for and build kitchen-diner rear extensions in Reading and the surrounding area, with one contract from the first survey to building control sign-off.

Reading sits in Berkshire, with postcode districts including RG1, RG2, RG4 and RG30. We usually keep the working kitchen where the old one was and put the dining table in the new space by the doors, which suits most Reading homes.

Your written price follows a measured survey and an agreed design, so it reflects your house, not an average.

Do you need planning permission for a kitchen-diner rear extension in Reading?

Planning for a kitchen-diner rear extension in Reading 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.

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 Reading like to extend?

Reading has a mix of Victorian terraces near the centre and larger Edwardian and inter-war houses further out. Clay soils across much of the South East mean deeper foundations near trees, which we plan for at the survey.

How a kitchen-diner rear extension in Reading 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. Written price, then build

    Once the design and approvals are in place, you get a fixed written price and programme, and we build through to sign-off.

FAQ

Kitchen-diner rear extension questions in Reading

Do you handle building control in Reading?

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

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.

Where does the cooker extraction go?

Through the new wall or roof, ducted to outside. Recirculating hoods are possible but less effective.

Will I need a structural engineer?

Yes for the beam over the new opening and usually the foundations; we arrange them and their calculations go to building control.

What postcode areas do you cover around Reading?

Including RG1, RG2, RG4, RG30 and RG31, and the surrounding Berkshire area.

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.
