Studio Ypsilon Ltd

What Studio Ypsilon Ltd does

Studio Ypsilon Ltd is a London-based interior architecture studio founded in 2015 by Yiannis Stylianou, operating from World's End Studios at 132-134 Lots Road, London SW10 0RJ. The firm provides bespoke interior design services for residential and communal spaces, targeting high-net-worth individuals and international property investors. Project work is concentrated in prime London postcodes — Mayfair, Marylebone, Holland Park, Knightsbridge, Notting Hill, St John's Wood, Soho, Chiswick, Bayswater, Hampstead Garden Suburb and Holborn — with additional commissions in Hertfordshire, including Bushey Heath and Totteridge.

The service offering is structured across four phases: Brief, Concept & Space Planning, Detail Design, and Realisation & Project Co-ordination, supplemented by procurement of furniture, fixtures and equipment. Revenue is generated through project-based design fees combined with margin on FF&E procurement via a curated supplier network (Camerich, Andrew Martin, VTWONEN, Kobe Fabrics, Fine Point Galleries). The business operates on an appointment-only basis with no public pricing, self-service channels, or standard productised offerings, and maintains a content presence across Instagram, Facebook, Houzz and a blog, supported by editorial features in Synthesis and Design Insider.

Studio Ypsilon is structured as a founder-led private limited company. There is no disclosed headcount, no external funding, no technology platform, and no AI/ML capability referenced in the public material. The operating model is project-based and dependent on referral-driven demand from a narrow pool of HNW and overseas-investor clients, which makes revenue inherently lumpy and tied to London prime-property transaction cycles.
