Bungalow rear extension in Wembley

Single-storey rear extensions that keep everything on one level. We design, get the approvals for and build rear extensions for bungalows in Wembley and the surrounding area, with one contract from the first survey to building control sign-off.

Wembley and its postcode districts HA0, HA9 and UB6 are part of our Greater London coverage. For Wembley bungalows we design the roof first, because the low eaves decide the height of the new room.

How much does a bungalow rear extension cost in Wembley?

For Wembley we work from the London rate: £2,400–£3,900 per square metre of new floor, including VAT, standard specification. London prices sit at the top of our range because of labour rates, access through the house, parking suspensions and skip licences.

3 m wide × 4 m deep (12 m²)£29,000–£47,000

Do you need planning permission for a bungalow rear extension in Wembley?

The planning route for a bungalow rear extension in Wembley 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. We check your house's planning history and any conservation area before drawing, so the route is clear before you spend on plans.

What are homes in Wembley like to extend?

Wembley is mostly 1930s semis, short terraces and post-war houses, so full-width single-storey and two-storey rear extensions are realistic on many plots. Some later estates had permitted development rights removed by condition, so we check the planning history first.

How a bungalow rear extension in Wembley comes together

  1. Free site visit

    We measure the house and garden, look at the back wall, drainage and boundaries, and talk through what you want from the space.

  2. Drawings and budget

    Floor plans and elevations for the options, each with a guide price.

  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.
