Design-and-build interior renovation in Singapore, from first drawing to handover.
Simplicity, sophistication and function, held together.
WK Design Space is a Singapore design-and-build firm founded by William Ng and Katherine Chai. We take a home from space planning through carpentry, electrical, plumbing and finishing — one team, one contract, one schedule.
Every space should combine practicality with aesthetics, and reflect the person living in it. That is the whole brief, and it is harder than it sounds.
Handover day. The part of the job that actually counts.

What we design and build
Six things we do, and the room we did each of them in.
Drawn → Built
Design-and-build for HDB flats, condominiums and landed homes — space planning, hacking, carpentry, electrical, plumbing and finishing managed end to end under one contract.
Custom kitchen carpentry built around how you actually cook, with our 10FT lifetime-warranty cabinet package and material selections made in our Yishun showroom.
Full-height wardrobes, walk-ins and concealed storage cut to the millimetre — the built-in joinery that makes a Singapore flat feel twice its size.
Quiet, warm bedrooms with integrated headboards, lighting and storage designed as one piece rather than furniture placed in a room.
Feature TV walls, ceiling detailing and lighting design that give the main living space a clear centre — the part of the home everyone sees first.
Offices, studios and retail interiors delivered around your operating hours, with proper submissions and compliance handled by our team.
