I got to know Alan from Zenith Arc when I was hunting for IDs to design & to renovate my hse. Alan is a very sincere person. He is very trustworthy. He is not someone who will persuade u to do unrealistic design. If anything, he is the one who will provide u with information with practicality & design within your budget. Alan is very efficient. If he says he going to draw up a proposal & quotation by next week, u better believe him as I said he is very efficient. Another thing is Alan is someone who understands your requirements very well. I did met some IDs who says they understand but they drew up a very different proposal, far from my requirements. Alan can already almost grasp my preference on our 2nd meeting. Take 1 look at Alan, u will know he is the creative kind.

Renovation is never an easy journey where there are many area to look into like budget, design, space, functions, details, time and commitment. And it requires a good teamwork, ideas and eye for detail to make it possible. I’m glad to have met Sally who partnered with me patiently to go through many hours of discussion, suggestions, choices and showcase of projects/samples where I was a noob.Sally is honest, diligent and efficient ID that guided me though. She also shared experiences and feedback so that I can make sound decision, she is also open and accommodating to my request and ideas to make the project possible. Even after receiving my keys, there were numerous adjustment made due to limitations of how the BTO is built and she is forthcoming to share what can be done and should be done. I’m very grateful to met her as she is commitment to visit and oversee the renovation occasionally and duly arranged contractors to carry out the job accordingly with quality, meeting my budget too! Thank you!

Marc was really great at helping us redesign our house to make it more spacious and elevated the space in the apartment that we have. it was our first project and he was attentive to our needs and helped us throughout, even as we were travelling during the 6 weeks which made it tough, but Marc made it work for us and we love our new home.

I worked with Javier and have no regrets at all. Javier and the team have been very supportive and kept to my tight timeline, despite certain unexpected issues relating to existing piping and wiring. We managed to fix everything in time. My new home turned out exactly as how I wanted it to. Thank you, Javier and Zenith Arc!

We are fortunate to know Wai Wai via HomeMatch. We were very impressed when she showed us the 3D design of our entire house even before we signed the contract with her, and were particularly amazed with the look of our proposed kitchen. Wai Wai is very patient and listen to our ideas. She will try to incorporate our ideas into her ID of the house and at the same time ensure the guys achieved our requirements. Wai Wai and us worked as a team and we were involved in all important meetings and discussions to ensure we were on the same page. We wish to thank Wai Wai for giving us a beautiful retirement home to live happily ever after.

This is my 2nd engagement with Zenith Arc. The first was during the Covid period in 2021 when I had my entire flat renovated. Whilst many have horror stories to tell about home renovation contractors, ours allowed us a good sleep every night. It has been 5 years — quality of renovation is solid, and service is no different after the project is over. So, for my 2nd property, I engaged Zenith Arc again as I know I can sleep well every night. I do not even have to visit nor supervise the work because I know it is in better care than what I can do. So, another great work done, this time under Marc Wong. Kudos again!!!
