Steff Cheng is the Founder and Principal Designer of Steff Stuff Design, a Los Angeles–based studio specializing in interior design and architecture. With more than 14 years of experience, she leads projects with a people-first philosophy – creating spaces that are not only beautiful and comfortable, but also efficient, memorable, and never boring.

Before establishing Steff Stuff Design, Steff contributed to residential, commercial, and hospitality projects across Los Angeles, the United States, and beyond. Today, her studio helps businesses, entrepreneurs, developers, and homeowners define their projects through design – whether it is a restaurant interior, apartment building, community space, or a custom-built residence.

She is an active member of AIA Los Angeles, the Urban Land Institute (ULI) through both the GROW and NEXT programs, and the Asian Business Association of Los Angeles (ABALA). Steff also serves on the ACE Next Gen Los Angeles board as a committee member, working on initiatives that empower small business owners to learn and thrive, as well as contribute to AAPI community endeavors, such as the annual APA Holiday Toy Drive.

Through both her design practice and community work, Steff promotes design as a tool for connection, identity, and inspiration – helping clients realize their projects through thoughtful, people-centered design.

Our studio is located in NELA, in the Eagle Rock neighborhood, bordering Pasadena.
