Luxury Interior Designers in London
1 Carlos Place, Mayfair, London. Grade II Listed.
Introduction
Supremati Interiors is a London-based luxury interior design studio known for crafting bespoke, timeless residential interiors - including projects in heritage, listed and high-end properties across the capital. With a foundation built on creativity, technical expertise and deep respect for architectural history, Supremati blends refined craftsmanship with a contemporary vision of luxury.
Our Approach to Luxury Interior Design
At Supremati, we believe that true luxury is curated, not imposed - it is about creating spaces that are not just visually exquisite, but deeply personal and functional. Our design philosophy emphasises harmony, balance, and emotional resonance, ensuring each home tells the story of its owners while transcending fleeting trends.
Rather than applying a one-size-fits-all style, we begin by understanding your lifestyle, routines, and aspirations, so that every element - from layout and materials to lighting and furnishings - supports both beauty and use.
Specialisation in Bespoke London Residences
Operating from London, Supremati has extensive experience working in some of the city’s most prestigious neighbourhoods - from Mayfair and Belgravia to South Kensington and Wimbledon. We have a particular expertise in:
Listed buildings (Grade I & II) that require sensitive preservation and integration of original architectural features
High-end homes where bespoke cabinetry, curated art, and premium materials define the living experience
Spaces that blend tradition and modernity, honouring heritage while introducing contemporary comfort and sophistication.
