Covering Thamesmead
Thamesmead sits 11 miles east of London, with Barking 3 miles to the north-west and Welling 3 miles to the south.

London projects often mean working on period terraces with neighbours on both sides, tight access through the house and conservation area controls, so careful planning and party wall work matter as much as the build.
What is a kitchen extension?
A kitchen extension is a single-storey extension designed around a new kitchen, usually creating an open-plan kitchen, dining and family space that opens onto the garden. Planning the kitchen layout at the same time as the building means the drains, steels, windows and power end up where the kitchen needs them.
- Combined building and kitchen layout design
- Planning or permitted development check
- Drainage, gas and electrics planned to the kitchen layout
How much should I budget for a kitchen extension?
Typical ranges for kitchen extensions. Ground conditions, access and specification move the final figure, which we fix in writing before work starts.

|---|---|
| Extension build | £2,600 to £4,000 per m² |

How is a kitchen extension approved in Thamesmead?
In England we deal with the council’s planning team for permission or a lawful development certificate, with building control (the council or a registered building control approver) for inspections, and with neighbours under the Party Wall etc. Act 1996 where it applies.
In England a single-storey rear extension can often go ahead under permitted development: up to 3 m deep on an attached house or 4 m on a detached one, no higher than 4 m, with eaves no higher than 3 m within 2 m of a boundary.
What can affect a kitchen extension?
- Islands with sinks or hobs need drainage and power routed in the slab.
- Underfloor heating suits large kitchen-diners with glazed walls.
What happens after I enquire?
- Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
- Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
- Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
- Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.
Questions about a kitchen extension in Thamesmead
How much does a kitchen extension cost?
The build is usually £2,600 to £4,000 per square metre including VAT, and the kitchen adds roughly £10,000 to £40,000 depending on the units, worktops and appliances.
Is underfloor heating worth it?
In large open-plan rooms with big glazed doors it frees up wall space and heats evenly. We include it as an option.
