Studio Hagen Hall is a London-based multidisciplinary design studio working across architecture, interiors, furniture, product and textiles. Research, materiality, craft and detail underpin every project, regardless of scale or typology. The studio balances beauty, pragmatism and comfort equally, producing work that is precise in its execution yet warm and approachable in character.

Founded in 2021 by Louis Hagen Hall, the studio has quickly established a reputation for thoughtful transformations of early to late modernist buildings. Prior to setting up the studio, Louis studied at the Royal College of Art and the Architectural Association, and gained experience with notable practices including Peter Eisenman, Seth Stein and DSDHA before establishing Studio Hagen Hall.

Since its founding, Studio Hagen Hall has been recognised for its ability to preserve and reinterpret modernist architecture with sensitivity and clarity. Awards to date include a 2025 RIBA London Award for Pine Heath and Best House Interior at the Dezeen Awards 2021 for Canyon House, with further shortlisting across the Architect’s Journal Retrofit & Reuse Awards and the British Homes Awards. In recent years, Studio Hagen Hall’s work has been widely published in national and international media outlets including Wallpaper, Architectural Digest, Elle Decoration, House & Garden, the Financial Times and the Observer. Louis Hagen Hall has also been nominated for the RIBA Stephen Lawrence Prize in 2025.

Studio Hagen Hall is an RIBA Chartered Practice and works with a close team of architects, interior designers and assistants, supported by a trusted network of craftspeople and consultants. Together they pursue projects that combine rigour and craft with the aim of producing spaces that are enduring, tactile and deeply lived in.

Robert Stephenson founded Sedilia in 1998, as a bespoke furniture-design and -making business that cut through the popular pre-fab trends of the time to focus on purity and quality. With over 20 years experience working on commissions for some of the best interior designers out there, Sedilia continue to celebrate the elegance of the essential by blending timeless design and innovation with edge, ease, balance and proportion.

Sedilia launched their own collection of furniture in 2019, which includes the ‘curvaceous croissant of indulgence’ – the Roll Top Chair, and the Sennen Sectional, which is designed to be a striking centrepiece. All of Sedilia’s designs take comfort as seriously as style, and combine a traditional approach with modern making methods to ensure long lasting results.
