“It was love at first sight as my Japanese tenant was deeply immersed in the ambience magically created by the team.”

One Catalyst is the best interior design company I’ve dealt with. The team is professional, friendly and helpful. They always kept me updated throughout the whole process, and gave me practical tips on renovation.

Not only was my unit turned astonishing, but it was also rented out within 2 weeks after completion. It was love at first sight as my Japanese tenant was deeply immersed in the ambience magically created by the team.

With One Catalyst’s design, I’m able to generate higher rental return without hustle & hassle. Bravo!

“…the reason I chose One Catalyst is because of their efficiency”

I act as representative for many foreign buyers in KL and the reason I chose One Catalyst is because of their efficiency. In this competitive market, I prefer to work together with someone who is efficient and responsive.

I’m impressed with the speed on how the founder responded to my request and it saved me a lot of hassle after my engagement with them as they are very accommodating. My tenants who are mainly from European countries and Japan love their design and the colours they choose makes the house feel very cosy.
