Fillet Edge is a multidisciplinary design studio, founded by Tianjian Li and Yifan Deng in 2022. Our areas of expertise include architecture design, interior design, creative concepting, and experiential design.

"Fillet Edge" in architecture symbolizes a harmonious blend of bold creativity and thoughtful refinement. Just as a fillet edge softens the sharpness of a corner, the agency embodies a philosophy of transforming rigid boundaries into seamless, elegant solutions. The name reflects the pursuit of balance—merging form and function, tradition and innovation, aesthetics and practicality. It suggests designs that are approachable yet striking, solutions that address complexity with grace, and a commitment to crafting spaces that connect people and environments in meaningful ways.
