House extensions in Kettering, designed around how you live
Extending is the most cost-effective way to gain space and value without the upheaval of moving. We design and build single and double storey extensions, kitchen and dining extensions and rear and side returns across Kettering and the surrounding Northamptonshire villages — matched to the town's red-brick Victorian houses and its modern estates alike. Every build meets Building Regulations and is signed off through Local Authority Building Control, with the planning or permitted-development route confirmed before we start.
The extensions Kettering homes ask for most
Kettering's housing runs from Victorian terraces to modern estates, and the right extension depends on the age and style of the property.
Victorian and Edwardian terraces near the centre often suit a rear or side-return extension to open a narrow kitchen into a single bright family space. This typically means removing a load-bearing wall and installing a steel beam to a structural engineer's calculations, which we do as standard.
Red-brick and ironstone period homes need matched brick and sympathetic detailing, and where a conservation area applies we prepare the work to the standard a conservation officer expects.
Modern estate homes around Barton Seagrave and the edges of Kettering frequently allow rear extensions under permitted development, avoiding a full planning application. We confirm the route at the first visit.
What Building Regulations cover
Every extension must meet Building Regulations regardless of planning: foundations sized for the ground, a damp proof course tied into the existing wall, insulation to current standards, structural support over openings, fire safety, ventilation and drainage. We build to those standards and arrange Building Control inspections at foundations, damp proofing, structure and completion — so you receive the completion certificate a buyer's solicitor will later want.

Design & approvals
We help with drawings, structural calculations, the planning or permitted-development route and the Building Control application.
Build & structure
Foundations, matched brickwork, steel beams, roofing and weathering — inspected at each stage.
"Opened up the back of our terrace into a big kitchen-diner and it's transformed the house. Skilled, tidy and reliable throughout."
Do I need planning permission to extend in Kettering?
It depends on the property. Many rear extensions on modern homes are permitted development, but conservation-area properties, listed buildings and larger extensions need full planning. We assess this at the first visit and explain the realistic route.
How long does an extension take?
Single-storey extensions usually run eight to fourteen weeks on site once approvals are in place; double-storey work takes longer. We give a realistic written programme.
Is the work properly certified?
Yes — built to Building Regulations, inspected by Building Control at the key stages, and issued with a completion certificate.
Can you match the existing brick?
In most cases yes. We source matched or closely blended brick and roofing so the extension reads as part of the original house.
