Caruso St John Architects

What Caruso St John Architects does

Caruso St John Architects is a London and Zurich-based architectural practice founded in 1990 by Adam Caruso and Peter St John, operating as a private partnership with 11-50 employees across two offices. The firm delivers full-service architecture including design, planning, and project oversight for cultural institutions, educational facilities, commercial real estate, residential developments, and large-scale sports and entertainment venues. Its portfolio spans more than 30 years, with landmark projects including the Tate Britain transformation (2007-2013), Nottingham Contemporary (2004-2009), New Art Gallery Walsall (2000), Newport Street Gallery, Royale Belge in Brussels, and the Swiss Life Arena (70,000m²) in Zurich completed in 2022.

The practice's core methodology centers on adaptive reuse and heritage conservation, with a stated philosophy of "understanding the past as present" that emphasizes careful dismantling, cataloguing, and reinstatement of original materials rather than demolition and new construction. Technical capabilities span traditional and contemporary materials including concrete, stone, timber, steel, MDF, plasterboard, and insulating glass. The firm has won multiple RIBA International Awards, MIPIM Awards, European Heritage/Europa Nostra Awards, and the Carlo Scarpa Prize for Gardens, and has published three volumes of Collected Works through MACK Books. Bavarian BIM-Award recognition for the Neue Pinakothek indicates adoption of Building Information Modeling.

Revenue is generated through professional services fees negotiated per project commission, secured primarily through invited architectural competitions, direct appointments with repeat clients, and collaborative partnerships with local practices in regulated European markets. Client base includes cultural institutions (Tate Britain, Nottingham Contemporary, Kunstmuseum Bern, Neue Pinakothek, Gagosian Gallery), educational bodies (Magdalen College Oxford, Hospitalfield Arts, Darwin College), corporate clients (AXA, Royal Belge insurance, Philips, Kvadrat, ZSC Lions), and public sector entities. The firm maintains no external investment, no parent company, and operates as an independent partnership with no disclosed ownership changes.
