A Jakarta architecture & interior design studio shaping private residences, commercial and office spaces — drawn, detailed and built under one roof since 2015.
We believe the world deserves design without boundaries — welcoming everyone, but dictating to no one. We work by your side, and on your side.
A design approach driven by the desire to deliver buildings which are as functionally efficient and high-performance as they are visually innovative — from first concept through approval and site supervision.

GREY is a Jakarta-based architecture and interior design firm founded by Olyvia Buana. Established in 2015, the studio works with both artistic and business-minded clients — from private residences to commercial and office projects.
Olyvia's passion for architecture and design began in Halifax, Canada and evolved at the University of Waterloo, where she earned an Honours Bachelor of Architectural Studies. We ask for a generous brief, an honest timeline, and the freedom to design slowly and well.
