About

Arteficius Design Studio is a high-end interior design studio specialising in renovation, interior styling, and design sourcing for a discerning international clientele.

Operating between London, Nice, and Milan, Arteficius blends Italian craftsmanship, Mediterranean warmth, and contemporary elegance to create spaces that are at once functional, refined, and emotionally resonant.

Originally founded in 2014 in London as Matter of Stuff, the studio was rebranded as Arteficius in 2023 under the sole creative direction of Simona Auteri.

With more than a decade of experience in interior architecture, furniture design, and materials curation, Arteficius has developed a distinctive aesthetic language rooted in storytelling, texture, and a deep sensitivity to context.

Alongside its interior design work, the studio has also led sustainable materials consulting missions for architecture firms, hotels, and cultural institutions — collaborating with clients such as the Victoria and Albert Museum, Sketch London, Ferrari, Kering, Argent LLP, Fora, The Office Group, and Anabela Chan Joaillerie.

Arteficius works in close partnership with master artisans, auction houses, and a trusted network of European partners, delivering interiors that are both meticulously crafted and deeply personal.

Whether reimagining a historic pied-à-terre, creating a turnkey project, or curating a bespoke furniture collection, each project is approached as a story told through space, material, and memory.
