Whether you are planning a spacious kitchen extension to change how you use your ground floor or a complex wraparound project, our team delivers a turnkey solution. We manage every structural element, from the initial foundations to the final plastering work. To ensure your new structural layout integrates perfectly with the rest of your property, we often recommend considering a property refurbishment to modernise existing rooms alongside your new build.

10/10 Renovation And Extension Work. Top Class

Excellent company, came to them with a renovation and an extension on my home and they were top quality start to finish.

Kept me informed at all times and were very flexible working around me and my family still living in the home. Met all my needs and were happy to make changes when asked. Price was very fair. The head of the company dzmitry is clearly very knowledgable and no nonsense, very professional. Can’t recommend enough.
