Interiors shaped by unique stories.
Sarah Mathieu works at the intersection of interior architecture, design and craftsmanship, creating spaces where people are at the heart of every intention.

A graduate of Penninghen School in Paris, she honed her eye at iconic Houses such as Liaigre, Baccarat and Tristan Auer. She has designed apartments
in New York, Paris, curated a clubhouse and created showrooms across Asia.
Nearly twenty years of experience have shaped a discerning, sensitive approach, driven by curiosity and inspired by encounters.

In 2025, she founded her studio to craft bespoke interiors in France and internationally. From sketch to completion, each project is born of a dialogue with the client and the place, infused with memory, history and identity.
Guided by skilled artisans and trusted partners, Sarah Mathieu designs timeless, vibrant environments where every detail contributes to harmony.
