What qualifications and experience do you have as an extension builder in New Malden?

An extension builder in New Malden 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.

What experience do you have with similar extensions in New Malden?

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 New Malden extension builder’s ability to deliver a result that meets your expectations.
