Sebastian & Jason worked closely with LTC playing a vital role in achieving the high-quality finishes we and the appointed design team set out to achieve. Sebastian & Jason are highly experienced professionals who were a pleasure to work with.

CJ Samui Builders have been superb, I only wish I’d have known about them before giving the job to the last lot.

I’ve seen some of their other building projects and they are doing 50m contracts and large hotels so completing villas on our development is a walk in the park for them.

We have been dealing with AJ, he is very easy to work with, always keeps to timeframes and I think the quality of his work is excellent. Obviously when you work with someone new you never know how things are going to work out but having known them now for 3 or so months I couldn’t be happier.

I know they are having to hire extra staff to keep up with demand as they are so busy which is always a good sign. I’ve heard from several people since that they are probably the best builder on the Island currently in terms of the quality of work and being in demand etc.

Sebastian (Bas) oversaw the complete building of our first villa (villa 8) from start to finish. He is really a great guy with significant experience. He also speaks fluent Thai. Bas has worked closely with myself and my partners (the designers) and was extremely valuable when it came to value engineering, design and dealing with vendors and subcontractors. He always has a good attitude and is very easy to work with.
