Spaces, well lived in.
Residential interiors, workplace design and outdoor living for people who want their space to feel effortless.
The studio
We bring experience, instinct, and a thoughtful eye — so the space feels unmistakably you.
McArthur Design Studio is a California-based residential and workplace interior design studio. We design rooms you want to stay in, and workplaces where people feel inspired to do their best work.
You don't need to know the right terminology, have an unlimited budget, or know exactly what you want before asking for help. Sometimes you just need someone who can see the potential.
