Design is our tool to create meaningful and inspiring human experiences.
Based in Toronto, with a practice that spans the world, we specialize in a wide array of work. From award-winning luxury hospitality, retail, and multi-unit residential design projects, to experimental exhibitions, with every project, we seek to broaden our insights to enrich the lives of everyone we touch.
Our founding partners Stanley Sun and Ashley Rumsey, bring international experience and a distinct perspective to the design process that combines art and science. No matter the project scale, or the location, our belief that design can create meaningful experiences remains steadfast.
Our talented team of design professionals works collaboratively with our clients to create unconventional solutions and a renewed perspective of everyday spaces. The team brings international experience with expertise from design development, technical drawing to construction coordination.

Stanley SunBID HONS, BSC HONS, NCIDQ, IDC, ARIDO, BCIN
Stanley Sun’s design vision is informed by a unique blend of formal studies in human sciences, fine arts and interior design training. Approaching each new design challenge with a combined scientific and humanistic perspective, he first observes how people experience and react to the built environment to then create a rational and intuitive design solution. Of particular interest to Stanley’s practice is the science of light, and the physiological and psychological response people have to lighting. Throughout his career, Stanley has led major interior design projects across Asia, North America and Europe. He recently led the award-winning Jing'An project in Shanghai. As an advocate for Canadian design, Stanley has been published widely and has participated as a keynote speaker at leading design conferences. He has also lectured as a sessional instructor at his alma mater, Ryerson School of Interior Design.
