Engaged my interior designer Ken Tay from Zenith Arc in 2024 for my condo renovations. He was able to provide suggestions and ideas to cater to my expected look and feel to the home. 2-3 years on, he is equally responsive and helpful to my asks. Great after sales support is something that is extremely rare and underrated in this industry that should not be taken for granted. I am glad to have made the right decision to engage Ken, no regrets.
