t-sa is an architectural atelier focused on producing work of enduring tactile quality. Its methodology deeply engages with each character of the specific context and materiality of each project. Context meaning the existing built fabric, its details, city, landscape as well as the stories and the narratives of the client and the inhabitants. Social, cultural, economical and political aspects of the background context also play important roles regardless of the scale of the project. t-sa believes in working with what already exists on site in the most economical means, delivering enriched and renewed built-life to each project. The notion of renewal is researched and investigated within the practice and through teaching at t-sa forum, our own independently run research school. Through materials and each specific context, t-sa has an interest in emotional qualities in the textures and tactility as well as connecting to the past and the future for each project environment.
From refurbishment of small spaces to new build projects, t-sa seeks for the core essence of each architectural challenge for our clients and aims to create timeless architecture with clarity and sensitive subtleties. It is helping to construct the future heritage of our built environment and landscapes.
t-sa was set up in 1996, founded by Yuli Toh and Takero Shimazaki. Formerly known as Toh Shimazaki Architecture, it works as a team discipline, often collaborating with designers, researchers and photographers on projects.
