Luxury Interior Design in Mayfair

Mayfair is London's most prestigious village — a neighbourhood of lateral apartments, grand townhouses, and some of the world's most valuable residential addresses. It is also home to Supremati's studio at 53 Davies Street, placing us at the heart of the luxury design world we serve.

Led by founder Magdalena Gruszczynska, with over 20 years of international design experience, Supremati has designed interiors for Mayfair's most discerning residents — creating spaces that are refined, considered, and entirely personal.

Designing for Mayfair's Most Prestigious Addresses

Mayfair's residential properties range from grand Georgian townhouses on Mount Street and Hill Street to sleek contemporary apartments overlooking Berkeley Square and Hyde Park. Each demands a different design response — but all share the same expectation of excellence.

At Supremati, we begin every Mayfair project with a deep understanding of the property's architecture and the client's way of living. Whether working with original period features or a blank canvas new-build, we deliver interiors that feel timeless, luxurious, and unmistakably individual.

Our Mayfair Projects

Our Mayfair portfolio includes a full interior design and project management commission for a luxury Mayfair apartment — covering space planning, bespoke joinery, material specification, and complete contractor coordination from concept through to practical completion.

Every Mayfair project we undertake is handled with the utmost discretion. We understand that our clients value their privacy as much as their homes, and we work accordingly.
