Founded in 1985, Architects Davidsson Tarkela is a Helsinki-based architectural firm that employs 17 people in both architectural and interior design. From 1991 to 1995, our head office was located in Berlin. Our implemented projects can be found in Finland, Berlin, Moscow and St. Petersburg.

aDT offers a wide range of design services to both public and private sector clients. Extensive expertise, close cooperation with the client and a networked design approach with other experts are at the core of our operations. Our work focuses on demanding renovations of historically valuable buildings, challenging new-construction projects, urban planning and project development. We operate reliably in a variety of project and implementation formats, utilizing the latest digital design tools.

Our approach is conversational and analytical. The possibilities of the site conditions and the needs of the project form the basis of the physical and cultural identity of each project. The pursuit of a carefully considered balance between our architectural heritage, resource-effective building design and a good urban environment guides all our design efforts.

Working within the built environment gives us the opportunity to promote sustainable architecture and the objectives of a carbon neutral society. Sustainable development and circular economy are key areas in the continued development of our operations.

The office is led by Aki Davidsson, Jaana Tarkela and Niklas Mahlberg, who serves as the office’s managing director. The entire management team works as design principals.

aDT is a member of The Association of Finnish Architects
