Marguerite Harrison trained at the Inchbald School of Design before spending several years working within an architectural practice in Paris, where she developed a deep understanding of how built space shapes the experience of daily life. She returned to London in 2009 and established her own studio three years later.

Her approach is grounded in a fundamental belief that the most enduring interiors are not those that follow movements or reference current aesthetic conversations, but those designed entirely around the people who will inhabit them. She refuses the idea of a signature style, preferring instead a signature rigour — a method that begins with observation and ends with rooms that feel inevitable.
