KITCHEN EXTENSIONS · DARLINGTON, NEWTON AYCLIFFE, MIDDLESBROUGH & BISHOP AUCKLAND
Kitchen extensions
in Darlington.
A bigger, brighter kitchen with room to cook, eat and sit together, opening out to the garden.
Peaks Construction Services builds single-storey kitchen extensions for homes across Darlington, Newton Aycliffe, Middlesbrough and Bishop Auckland, from the foundations to the roof lantern and the finished floor.
WHAT THE JOB INVOLVES
Open-plan,
full of light.
Most kitchen extensions are single-storey rear extensions. The old back wall usually comes out and a steel beam goes in, so the new space and the existing kitchen become one open-plan room. A roof lantern or rooflights bring daylight into the middle of the room.
A kitchen extension usually includes:
- Foundations, drainage and the new floor slab
- Walls, insulation and the roof structure
- A roof lantern or rooflights, and doors to the garden
- Steel beams where the existing wall is opened up
- Plastering, flooring and first and second fix
- Finishing joinery, such as skirting, linings and fitted storage

HOW PEAKS RUNS IT
Step by step,
one team.
You deal with Danny from the first visit to the final snag.
How your project runs
- Site visitDanny looks at the house, the garden and the wall you’d like to open up, and talks through layout, light and budget.
- Drawings & planningWe help arrange drawings, and a planning application where one is needed. Danny will check whether permitted development could apply.
- Building ControlWe arrange Building Regulations approval and inspections, and coordinate the structural engineer’s calculations for any steel.
- The buildFoundations, walls, roof, lantern and doors, then the steel goes in and the old wall comes out, with regular updates.
- Finishing joineryPlastering, flooring, skirting and fitted joinery, so the room is ready for the kitchen and for living in.
WHAT AFFECTS THE COST
Every job
is priced on its own.
Danny gives you a clear written quote after the site visit. These are the main things that change the price of a kitchen extension.
- 01
Size and layout
The floor area, the shape of the extension and how much of the existing wall is opened up.
- 02
Ground and drains
Ground conditions, nearby trees and any drains under the build can change the foundations needed.
- 03
Roof and glazing
A roof lantern, rooflights and large sliding or bi-fold doors each add to the specification.
- 04
Finish
Flooring, lighting, heating and the level of fitted joinery you choose for the finished room.
PLANNING & BUILDING REGULATIONS
The rules,
checked first.
In England, many single-storey rear extensions can be built under permitted development, within limits on size, height and position. It depends on your house, its location and any earlier extensions, so Danny will check with you and you can read the guidance on the Planning Portal. Larger extensions may need planning permission or prior approval.
Building Regulations approval is needed for a kitchen extension. Any steel beams need a structural engineer’s calculations. If you are building close to a shared boundary, the Party Wall Act may also apply.
HOW LONG IT TAKES
Realistic
timescales.
A kitchen extension is a bigger project, usually measured in weeks to months on site depending on size and specification. Drawings, approvals and lead times for items such as the roof lantern and doors all need planning in before the build starts.

QUESTIONS WE GET ASKED
Kitchen extension questions,
answered.
Something else on your mind? Ask Danny when he comes out to look at the job.
- 01
Can I still use my kitchen during the build?
Usually for much of it. The extension is built first and the old wall opened up later.
- 02
Do you fit roof lanterns?
Yes. Roof lanterns and rooflights are a popular way to bring daylight into the middle of a deep kitchen extension.
- 03
Will I need a steel beam?
If the existing back wall is being opened up, almost always. The steel is sized by a structural engineer and checked by Building Control.
- 04
Do you fit the kitchen too?
We can handle the joinery side, including kitchen fitting, worktops and fitted storage. Talk to Danny about what you have in mind.
