What Takero Shimazaki Architects does

Takero Shimazaki Architects (t-sa) is a London-based architectural practice founded in 1996 by Yuli Toh and Takero Shimazaki, operating as a privately held studio of approximately 10-15 staff under principal director Takero Shimazaki. The practice provides architectural design services across residential, cultural, commercial, and institutional projects, with a distinctive methodology centred on renewal, refurbishment, and adaptive reuse of existing buildings rather than new-build construction. Core technical differentiators include a focus on tactile materiality, the layering of existing and new materials (e.g., pink concrete, hand-applied plaster, bronze ironmongery), and contextual engagement with heritage and listed structures, exemplified in projects such as Curzon Bloomsbury, the Royal Academy of Dance headquarters, and Prewetts Mill.

The firm operates a professional services revenue model, with fees negotiated per project based on scope, scale, and complexity under multi-year contracts. Work is acquired through direct commissions, invited architectural competitions (notably the Prewetts Mill win in 2016), and referrals from a network of private clients and cultural institutions. GTM motion is therefore sales-led alongside a community-led channel via the t-sa forum research school (established 2006) and continuous academic engagement at the Architectural Association, The Cass, Cambridge, and Cardiff. The studio is supported by long-term collaborations with specialist contractors and engineers (e.g., Webb Yates, New Wave London) and a co-development partnership with Samuel Chisholm Studio on the Oru Sutton re-use project.

Customer segments span high-net-worth private residential clients, cultural and educational institutions (Royal Academy of Dance, Leicester Print Workshop, The Yard Theatre), cinema and entertainment operators (Curzon Cinemas), and real estate developers (Prewetts Mill). The practice has won multiple RIBA National Awards, RIBA London Awards, the Manser Medal (AJ House of the Year 2025) for Niwa House, and was shortlisted for the RIBA Stirling Prize 2025, indicating strong reputation within the UK architecture sector. Operations remain geographically concentrated in London, the South East, and the Midlands, with no international expansion or external investment disclosed.
