Our profile
A Singapore interior design and renovation company, built on getting the unglamorous parts right.
Company introduction
Design and build, under one contract.
WK Design Space is a Singapore-based interior design and renovation company specialising in residential and commercial projects. We provide complete design-and-build solutions, focusing on practical space planning, refined aesthetics and high-quality workmanship.
From concept design to renovation completion, every project is carefully managed to ensure a smooth, safe and professional renovation experience.
The company was founded by William Ng and Katherine Chai, with the aim of delivering reliable renovation work together with thoughtful and functional interior design for homeowners in Singapore.
Every project starts on paper before it starts on site.
Showroom & customer experience
See it, touch it, then decide.
We operate a dedicated showroom in Singapore where homeowners can explore design ideas, materials and renovation solutions in person.
We regularly organise renovation events and showroom sessions, giving customers access to special upgrades, exclusive selections and more premium material and product options.
The showroom introduces current market trends, modern materials and new renovation technologies, so every project uses up-to-date products that meet today's design and quality standards. You understand workmanship details and material differences before you start, not after.
