Founded by Magdalena Gruszczynska, Supremati is a London-based luxury interior design studio creating bespoke residential and commercial interiors that are soulful, curated, and quietly bold.
With a focus on timeless elegance, material integrity, and layered detail, we design interiors that feel both deeply personal and beautifully resolved. From private residences to distinctive office spaces across London, every project is a collaboration - rooted in listening, shaped by intuition, and guided by meaning over trend.
Our approach to luxury interior design is meticulous yet expressive, tailored yet imaginative. Through thoughtful curation, architectural sensitivity, and an unwavering eye for detail, we transform spaces into refined, enduring interiors that resonate long after they are experienced.
