Kitchen-diner rear extension in Tooting

We plan and build kitchen-diner rear extensions for homeowners in Tooting. An open-plan kitchen, dining and family room that opens straight onto the garden. Start with a free site visit, then a written price once the design is agreed.

Tooting and its postcode districts CR4, SW12 and SW17 are part of our Greater London coverage. A kitchen-diner is often the reason people in Tooting extend: the back kitchen in inter-war semis and terraces is rarely big enough for a table.

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

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

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. Before any drawing we look up the property's history with the council, because earlier extensions and removed rights change the answer.

What are homes in Tooting like to extend?

Much of Tooting is 1920s and 1930s semis and short terraces with longer gardens than inner London, which suit full-width single-storey rear extensions. Parking suspensions, skip licences and controlled hours on residential streets shape the programme more than the build itself.

How a kitchen-diner rear extension in Tooting 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. 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. 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. 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.

FAQ

Kitchen-diner rear extension questions in Tooting

What postcode areas do you cover around Tooting?

Including CR4, SW12 and SW17, and the surrounding Greater London area.

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

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

Should the sink face the garden?

If the plan allows, an island sink or hob facing the glass is a common choice. It needs a floor-level drain run, which is easy to lay in a new slab.

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

Is the site visit in Tooting 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 Tooting?

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.
