American interior designer Amber Lewis is the founder and principal designer of Los Angeles-based Amber Interior Design Studio. Known for creating interiors that feel relaxed, layered and deeply personal, Lewis has developed a distinctive aesthetic that balances California ease with vintage influences, natural materials and contemporary design.

Her work is less about adhering to a particular period or style and more about creating spaces that feel as though they have evolved naturally over time. Warm woods, tactile textiles, aged finishes and collected objects are recurring elements—creating interiors that are refined while remaining approachable and livable.
