Had a very good initial meeting with JMA Group represented by Sunnie. Sunnie first briefed us thoroughly about their company - what they do and how they operate as regards their projects. Then we had a very positive discussion about our own planned project , a single storey extension with internal alterations. He made very interesting recommendations, which we are now considering to adapt. We are still in the negotiating process, but we hope to come up with a mutually beneficial agreement to get this project going. Very happy so far with the way they deal with us - very professional. Thank you Sunnie!Posted on Sebastian MuthuparakunnelTrustindex verifies that the original source of the review is Google. We had an excellent experience with Sunnie!

His knowledge and communication were outstanding — we couldn’t have asked for better guidance. Highly recommended!Posted on MatthewTrustindex verifies that the original source of the review is Google. Initial survey meeting was very good.
