Our Perspective

With a background in architecture and international experience across Hong Kong and California,our studio brings a global perspective to residential design.

We are drawn to:

natural materials and honest textures
warm, minimal compositions
quiet contrasts in tone and form

Our work balances structure and softness—creating homes that feel both grounded and lived-in.

Beyond Interiors

We are developing a curated collection of objects and materials—
including stone pieces and home accessories—
that extend our design language beyond the built space.
