Designed around how you live.
Detailed for how it gets built.
I'm Guo Lun. I plan the layout, design the home, draw what the contractor builds from, check what you're paying for, and stay on it through handover. One person, start to finish.
For HDB resale, BTO and condo owners who want the layout resolved and the build documented properly.

Most renovation problems start before construction.
How life flows.
Resolving daily habits, circulation, and space planning.
How it is designed.
Curating materials, proportions, and visual coherence.
How it is built.
Documenting drawings, specifications, and exact scope.
It is usually a layout that doesn't fit how you live, or drawings too vague to build from. Decide it on paper, not on site. Changes on site cost the most.

The design doesn't stop at the render.
A render shows the look. The builder works from drawings: dimensions, specifications and construction details. I draw them so the design you approved is the one that gets built, with fewer questions on site.
Know what you're buying before construction begins.
