We are a Helsinki-based architecture and design agency. Our specialties are residential design and designing of exhibitions.
Tuomas Siitonen has a M.Sc. in Architecture from Helsinki University of Technology and M.A. from the Graphic Design department of Helsinki University of Art and Design. Combining these skills in actual projects since around 2001 Tuomas launched Tuomas Siitonen Office in 2010.
Since then our small and flexible team has worked on projects for public and private clients. Our public clients include The National Museum of Finland, HAM Helsinki City Art Museum and Design Museum in Helsinki. For private clients we have designed a number of houses and smaller dwellings, often on demanding sites in urban context. View the client list.
The work of Tuomas Siitonen has been exhibited in various occasions, including the Biennial Survey of Finnish Architecture and the Venice Biennale. It has also been featured by Dezeen, Dwell, ArchDaily and others. Links to selected articles.
In addition to running the office Tuomas Siitonen has a lecturer position in the Department of Architecture, chair of Architectural Principles and Theory of Aalto University and does visiting lectures and workshops on a regular basis.
