Bungalow rear extension in Cricklewood
Single-storey rear extensions that keep everything on one level. We design, get the approvals for and build rear extensions for bungalows in Cricklewood and the surrounding area, with one contract from the first survey to building control sign-off.
Cricklewood sits in Greater London, with postcode districts including NW2, NW6 and NW11. For Cricklewood 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 Cricklewood?
A bungalow rear extension in Cricklewood is priced at £2,400–£3,900 per square metre including VAT as a guide, before kitchen fit-out and fees. London prices sit at the top of our range because of labour rates, access through the house, parking suspensions and skip licences.

| 4 m wide × 6 m deep (24 m²) | £57,500–£93,500 |
These are guide ranges; the written quote after the survey is the figure that counts.
Do you need planning permission for a bungalow rear extension in Cricklewood?
Whether your bungalow rear extension in Cricklewood needs a planning application depends on its size, your house and any local restrictions.
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 Cricklewood like to extend?
Period terraces in Cricklewood sit alongside flats, and the difference matters: houses usually keep permitted development rights, while flats and maisonettes need planning permission for any rear extension.

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

Can I extend the loft as well?
Sometimes, but that is a different project; a rear extension keeps everything on one level.
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.
Is the site visit in Cricklewood free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
Can you match the brick or stone on my Cricklewood house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
