House Extensions in Kent
From rear extensions to wraparounds, we design and build extensions that transform how you live.
Extensions built around the way you live
For over 25 years, we have helped a varied clientele across Kent transform the way they live through thoughtfully designed, high-quality home extensions. From rear extensions and side returns to wraparounds and double-storey additions, we create spaces that not only add value to a property, but completely change how a home feels and functions.
Whether it is opening up a kitchen into the heart of the home, creating brighter family living spaces, or adding much-needed room for a growing household, every extension is designed to feel seamless with the existing property and built to stand the test of time.

Open-plan kitchen extension on a Victorian terrace
- Beckenham, BR3
- 16 weeks on site
- £94,500 + VAT
Challenge
The clients had a long, narrow Victorian terrace with a dark galley kitchen and a separate dining room they never used. They wanted one open-plan space across the back of the house with bifold doors to the garden, but the side return was only 1.4m wide and the existing rear wall was load-bearing on a chimney breast. Two previous builders had quoted £140k+ and a 9-month programme.
Solution
We designed a wraparound extension under permitted development — 3m rear projection plus the full side return — sitting on a piled foundation to avoid a row of mature trees on the boundary. A 6.5m steel goalpost replaced the rear wall and the chimney breast on the ground floor. New kitchen run along the side return, island in the middle, dining table where the old kitchen sat, and 4-panel aluminium bifolds across the back. Underfloor heating on engineered oak throughout.
Outcome
Finished on programme, £900 under budget, and the clients moved back into the kitchen the day before Christmas. Two of their immediate neighbours have since asked us to quote similar projects on the same street.
Typical timeline
12–20 weeks on site for a typical single-storey extension; 16–24 weeks for double-storey. Add 8–12 weeks before that for design, planning and building control if needed.
Pricing guidance
Most single-storey extensions in our area run £2,200–£3,200 per m², depending on glazing, finishes and groundworks. Double-storey is typically £2,800–£3,800 per m². Every quote is fixed and itemised — no day-rate surprises.

Do I need planning permission for an extension?
Many single-storey rear extensions fall under permitted development. Larger projects, double-storey work or anything in a conservation area usually needs full planning. We'll confirm in the first site visit.
How long is the disruption?
We hoard the work area, set up dust protection and keep your kitchen functional as long as possible. Most clients can stay in the house throughout the build.
Can you work with my architect?
Yes — we work with your drawings or introduce you to a trusted local architect if you don't have one.
What guarantee do you offer?
10-year structural guarantee on all extensions plus 12 months on workmanship and finishes.
