Kitchen-diner rear extension in Horwich

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 Horwich and the surrounding area, with one contract from the first survey to building control sign-off.

Horwich is covered from our Greater Manchester round, including BL6. A kitchen-diner is often the reason people in Horwich extend: the back kitchen in stone and brick terraces is rarely big enough for a table.

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

The planning route for a kitchen-diner rear extension in Horwich is set by England's householder rules and your council.

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.

England also has the larger home extension route: a single-storey rear extension of up to 6 metres on an attached house or 8 metres on a detached house, after prior approval from the council. The council notifies your neighbours and has 42 days to decide; the fee is £249 (£310 for applications made from 8 December 2026). The route is not available on designated land such as conservation areas.

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 Horwich like to extend?

Stone and brick terraces are common around Horwich. Where houses back onto a ginnel or alley, deliveries can come in from the rear, which makes the build tidier.

How a kitchen-diner rear extension in Horwich 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. Design and guide price

    Two or three layout options with a guide price for each, so you choose the design knowing what it costs.

  3. Approvals

    Permitted development check, prior approval or planning application, then Building Regulations drawings and structural calculations, plus party wall notices where they apply.

  4. Build and sign-off

    We build to the approved drawings with regular updates, then hand over the building control completion certificate and any guarantees from suppliers.
