Caruso St John Architects, founded in 1990 by Adam Caruso and Peter St John, maintains offices in London and Zurich. The Zurich branch, opened in 2010, oversees a growing portfolio of Swiss projects amid the firm's expansion into urban developments across Europe. With over 25 staff across sites, the practice handles commissions from museums to housing, often collaborating with artists like Thomas Demand and Damien Hirst.
Early recognition came from the 1995 New Art Gallery Walsall competition win. In Zurich, the firm delivered the Swiss Life Arena in 2022, its largest project at 12,000 seats for ZSC Lions ice hockey, which earned the 2025 Audience Award from Zurich Canton's Foundation for Good Buildings. The 9,300-square-meter Office Building at Escher Wyss Platz (2017-2020), costing 21.5 million CHF for client Allreal West AG, sits amid Zurich West's industrial remnants and new towers.
Current Zurich work includes the seven-story AXA office on Stampfenbachstrasse, with 4,000 square meters of space featuring quarried Verde Spluga stone cladding and a central polished stone column installed in 2024; Gutstrasse cooperative housing in Wiedikon, where tilted corrugated panels and yellow accents define topping-out buildings A and D; and Hardturm Areal's West Tower, clad in folded chrome-steel sheets. Retail fit-outs, like Opia Store on Sihlstrasse opened November 2025, integrate custom lighting and displays. Planning advances for apartment blocks in Lucerne's Eggen and Tribschenquartier, plus renovations of listed sites like Cham's Durolux Building. Adam Caruso teaches at ETH Zurich, linking academia to practice.
