Lee converted our property from a 4-bedroom house into a 6-bedroom HMO, and he did an amazing job while keeping to the agreed 6-month timeline. Lee and his team delivered on every expectation at every stage of the project, which included a loft dormer conversion and a rear extension. They also completed six en-suite bathrooms, a new kitchen, a full rewire, plastering throughout, plumbing, joinery works, damp-proofing works, and installed new fire escape windows throughout the property. Lee managed the entire process professionally and ensured everything was signed off by Building Control. To date, Lee and his team have completed six properties for us, and we will continue to use them in the future because of their reliability, professionalism, and consistently high standard of workmanship. We would highly recommend Lee and his team to anyone looking for quality building work.

What qualifications and experience do you have as an extension builder in County Durham?

An extension builder in County Durham should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

What experience do you have with similar extensions in County Durham?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the County Durham extension builder’s ability to deliver a result that meets your expectations.
