About Supremati Interiors

Supremati is a London interior design studio for clients who expect the senior team they meet on day one to be the team that delivers their home. Founded in 2017 by Magdalena Gruszczynska, the studio designs highly considered interiors for private clients and developers across Mayfair, Belgravia, Regent's Park, Wimbledon Village and St John's Wood — with particular expertise in listed and heritage properties. Every project is led personally by Magdalena from first concept to practical completion, supported by a trusted team of specialists. No handovers, no fading senior involvement — the same experienced eye on every meeting, every decision, every site visit. Recent projects include a Grade I listed eight-bedroom house at Regent's Park, a Grade I listed townhouse in the heart of Belgravia, and a Grade II listed apartment on Carlos Place whose interiors helped the developer generate £2 million in sales revenue. Refurbishment budgets range up to £25 million, and Supremati's work has been featured in Mayfair Magazine, The London Magazine, Archello and Designeers. Our work moves through five clear stages — concept, design development, technical drawings and procurement, construction, and final installation — with weekly site attendance through the build, written schedules, and straight answers throughout. We believe true luxury is curated, not imposed: interiors that are refined, deeply personal, and true to the architecture around them. Services: interior design for residential and commercial spaces · design management through practical completion · design consulting. Planning a refurbishment, or advising a client who is?
