House Extension & New Build Builders in Kent
Extensions and new builds from the footings up, with brickwork we are proud of.
Adding space to your home is a big step, and the structure has to be right. We build single and two-storey extensions, garage conversions, garden buildings and new builds, handling groundworks, foundations, drainage and the brick and blockwork shell.
Our background is brickwork and groundworks, so the parts that matter most to how an extension performs are done by us, not passed around. We work to approved drawings, agreed specifications and building control inspections, and keep you informed at each stage.
Once the shell is complete, we can coordinate with roofers, carpenters, electricians and plumbers, or work alongside a main contractor or architect you already have in place.
Options
Choosing what’s right for you.
Single-storey rear extensions
The most common way to add a larger kitchen or living space. Many fall within permitted development, although limits apply to depth and height.
Two-storey and side extensions
More space for the investment, but usually need planning permission and more structural design.
Garage conversions
Often a cost-effective way to add a room. Floors, walls and the garage door opening need upgrading to meet building regulations for insulation and damp.
New builds
Full houses and outbuildings built to approved plans. We handle groundworks and the masonry structure and work with the wider team to completion.

Worth knowing
Before you start.
- 01
Planning permission
Some extensions fall under permitted development, while others need full planning permission. Conservation areas, listed buildings and previous extensions change what is allowed. Check with your council or a designer before committing.
- 02
Building regulations
Almost all extensions need building regulations approval, covering foundations, structure, insulation, drainage and fire safety. Work is inspected at key stages.

Questions
Extensions & New Builds: common questions.
Do I need planning permission for an extension?
Not always. Many single-storey rear extensions are allowed under permitted development within size limits, sometimes with a prior approval process. Larger, two-storey or side extensions, and homes in conservation areas, usually need permission. Your council or designer can confirm what applies to your home.
Do you provide drawings?
We build from approved drawings. If you do not yet have an architect or designer, we can suggest how to get plans prepared, and we are happy to review drawings for buildability before you finalise them.
How long does an extension take?
It varies with size, design and weather. The groundworks and shell are usually a matter of weeks, with finishing trades following on. We give you a realistic programme once we have seen the drawings and site.
Can I stay in my home during the work?
In most cases, yes. We plan the build to keep disruption down, keep the site tidy and secure, and agree working hours and access with you before starting.
