House extensions across London
More space without the cost and upheaval of moving. We build rear, side return, wraparound and double-storey extensions, from the foundations to the finishing inside.
What we do
More space without moving. We build rear, side return, wraparound and double-storey extensions, taking care of the structure, the roof and the finishing inside.
- Foundations and structure
- Brickwork and roof
- Openings for bi-fold or sliding doors
- Plastering and finishing inside
The work in detail
Every job is different. These are the kinds of work we take on under extensions.
- Rear extensions
Single-storey extensions that open the back of the house onto the garden and give you a bigger kitchen or living space.
- Side return extensions
Using the narrow strip beside a terraced house to widen the kitchen and bring light into the middle of the home.
- Wraparound extensions
Combining a rear and a side return to transform the whole back of the house in one project.
- Double-storey extensions
Adding space on two floors, such as a larger kitchen below and a bedroom or bathroom above.
- Foundations and groundwork
Digging, laying foundations and getting the groundwork right, because everything else depends on it.
- Brickwork and structure
Building walls, openings and supports so the new space is solid and matches your existing house.
- Roof and weatherproofing
Pitched or flat roofs, rooflights and the details that make the extension watertight.
- Internal finishing
Plastering, floors, joinery and decoration, so the new room is ready to use the day it is handed over.
How a extensions project runs
From your first message to the finished job, so you always know what happens next.
Visit and brief
We see the property and the garden, and talk through what you want the new space to do.
Planning and permissions
We talk you through whether planning permission or building regulations are likely to apply to your project.
Groundwork and structure
Foundations, walls and openings, with the house protected and your access kept as clear as possible.
Roof, openings and weathertight
The roof goes on and the openings are fitted so the build is dry before finishing starts.
Finishing and handover
Plastering, floors and decoration, then a walk-through to make sure it is exactly right.

Extensions: common questions
Can't see your question? Send us a message and we'll answer it.
Do I need planning permission for an extension?
It depends on the property and the size of the extension. Some can be built under permitted development rights while others need planning permission. We will talk through what is likely for yours.
What is the difference between a side return and a wraparound?
A side return fills the narrow strip beside the house. A wraparound combines that with a rear extension for a larger, single space.
Can I stay in the house during the build?
Often yes, though the kitchen may be out of action for part of the time. We will talk through what is realistic.
Can you fit large sliding or bi-fold doors?
Yes. Large openings are a common part of an extension and are built with the right support.
How long does an extension take?
It depends on the size and type of the extension. Once we have seen the property we can give you a realistic idea.
