Covering St Albans
We work in St Albans (AL1, AL3) and the places around it, including Harpenden, Hatfield and Hemel Hempstead.
Homes in the East of England
The East of England has a large stock of post-war and modern estate housing alongside period homes in market towns, which makes garage conversions, single-storey extensions and loft conversions popular.
What does a kitchen extension involve?
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
- Steelwork, roof, glazing and insulation

Do you need permission for a kitchen extension in St Albans?
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.
- Worktops are templated after the units are fitted, adding a short gap before completion.
From first call to completion
- 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.
- Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
- Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
Your questions answered
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.
Can you visit a house in St Albans to quote?
Yes. After a short call we arrange a site visit to measure up and agree what the design needs to do, then send a written price.
