Covering Tonbridge
Alongside Tonbridge, we also cover Tunbridge Wells, Sevenoaks (6 miles to the north-west) and Crowborough.
Homes in the South East
The South East has a lot of 1930s and post-war semi-detached housing, well suited to rear extensions and hip-to-gable loft conversions, alongside period properties in conservation areas that need a more careful design.
What goes into 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.
- Planning or permitted development check
- Drainage, gas and electrics planned to the kitchen layout
- Kitchen fitting, worktop templating and appliances

What approvals does a kitchen extension need in England?
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 change the price or programme?
- Islands with sinks or hobs need drainage and power routed in the slab.
- Underfloor heating suits large kitchen-diners with glazed walls.
