House Extensions in Bath & Across Somerset
CJM Build carries out home and house extensions across Bath, Radstock and the surrounding Somerset area. From kitchen extensions and open-plan living spaces to additional bedrooms and family rooms, we manage the build from the initial groundwork through to the final finish.
We undertake single-storey, double-storey, side and rear extensions, as well as porches and other home alterations. Every project is planned around the existing property, the space available and how you want the new area to work for your home.
Why Choose to Extend
A well-planned extension can give you the extra space you need without the upheaval of moving. It can improve the way your home works day to day, create a larger kitchen or living area and make better use of the space already available around your property.
Some of the main benefits of a home extension include:
- More Space
- Built Around You
- Added Value
- Better Layout
We can talk through the options for your property and recommend a practical approach based on the existing house, available space and the type of extension you have in mind.
Types of House Extensions We Build
Every home is different, so extensions need to be planned to suit both the property and how you want to use the space. We take on a range of extension projects, from more traditional builds to modern designs, making sure everything ties in properly with the existing structure.
Some of the common types of extensions we carry out include:
Single-Storey Extensions – Ideal for larger kitchens, open-plan dining areas and additional ground-floor living space.
Double-Storey Extensions – Creates additional space on both floors and can work well for extra bedrooms, bathrooms or larger family homes.
Side Return Extensions – Makes use of narrower space beside the property, often allowing an existing kitchen or living area to be opened up.
Rear Extensions – Extends into the garden to create larger kitchens, dining areas or additional living space.
Wrap-Around Extensions – Combines side and rear extensions to significantly change the layout and usable floor area.
Porch Extensions – Adds a practical entrance area while improving storage, appearance and weather protection.
We’ll help you choose an extension layout that works with the existing property, available space and what you want to achieve.

Frequently Asked Questions
The cost of an extension depends on the size, design and level of finish. Smaller single-storey extensions will cost less than larger or double-storey builds, and things like ground conditions and materials can also affect the price. The best way to get an accurate figure is to have a look at the property and discuss what you’re looking to achieve.
Not every extension requires a full planning application, as some projects may fall within permitted development rights. This depends on factors such as the size, height, position of the extension and the property itself. We can discuss this during the planning stage and help you understand what may be required before work begins.
Timeframes vary depending on the size and complexity of the project. A straightforward single-storey extension may take a few weeks, while larger or more detailed builds can take longer. We’ll give you a clear idea of timescales before starting and keep things moving as smoothly as possible
