Groundwork & Foundations- 25 Jul 2023
The Oreilly Group completed my groundworks, external drainage and some knock throughs on my extension. The job commenced when promised and was completed within programme. The works were completed on time and this included some extras I threw in along the way. I would reccomend Owens team for any groundwork and drainage project - very happy with the outcome.

What qualifications and experience do you have as an extension builder in Grays Inn?

An extension builder in Grays Inn 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 Grays Inn?

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 Grays Inn extension builder’s ability to deliver a result that meets your expectations.
