What qualifications and experience do you have as an extension builder in South Hampstead?

An extension builder in South Hampstead 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 South Hampstead?

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 South Hampstead extension builder’s ability to deliver a result that meets your expectations.
