What experience do you have with similar extensions in West Midlands?

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 West Midlands extension builder’s ability to deliver a result that meets your expectations.
