Thank you very much for your interest.
If you’re thinking about extending your home, now is a fantastic time to do it.
We are currently offering fully finished extensions from just £2,000 per sqm, including the full Building Control process.
You’ll receive a fully insulated, high-quality extension built on a concrete foundation and designed to comply with Building Regulations. Where required, the structure is fully fire-rated, giving you comfortable, permanent living space that becomes a seamless extension of your home.
Why spend significantly more on traditional construction when you can achieve the same result for a much more competitive price?
Whether you’re creating a larger kitchen, open-plan living area, dining room, home office, playroom or extra family space, an extension is one of the best ways to increase both your living space and your property’s value.
Our standard specification includes:
- Fully insulated construction
- Concrete base
- Building Control approval process included
- Grey uPVC French doors (white inside)
- High-quality external finish
You can also customise your extension with:
- Additional windows
- Large sliding doors
- Aluminium bi-fold doors
- Rooflights or roof lanterns
- A wide range of other optional upgrades
Fast installation
One of the biggest advantages of our system is speed.
Our current lead time is approximately 1–2 weeks, and most extensions are completed in around 2 weeks, depending on the size and specification.
Our minimum project size is 12 sqm, although we can build both smaller and much larger extensions to suit your requirements.
