The studio

INTERIOR DESIGN
With over 15 years of experience renovating Haussmann-style apartments in Paris, I offer recognised expertise in interior renovation and bespoke design. Based in Barcelona since 2023, I have joined forces with Maison Margaux Valla, an interior design studio from London, to create a duo of interior designers firmly focused on creativity and customer relations. Together, we assist private individuals and professionals with their apartment and commercial space renovation projects in Barcelona.
Multilingual (French, Spanish, English) and capable of managing a variety of projects, we assist our clients with everything from renovating a house on the Costa Brava to designing unusual spaces in Barcelona.
The studio assists individuals and professionals in the design, renovation and layout of bespoke spaces, combining creativity, functionality and aesthetics. We support you from start to finish to ensure a bespoke, harmonious and turnkey result.
