Tuomas Seppänen appointed as Director, EVP at ONE Architects

Architect Tuomas Seppänen has been appointed as Director, EVP at ONE Architects and Business Area Director at AINS Group. At the same time, the organization is being renewed to support the evolving strategy of our architectural services.

Architect SAFA Tuomas Seppänen takes on the roles at the beginning of September. Having worked as a Lead Architect at ONE Architects and previously at B&M, Tuomas is particularly recognized for his expertise in real estate development and urban planning. The previous Director, EVP Jaakob Solla continues in a Senior Architect role at his own request, focusing on business development, sales, and lead designer assignments.

"We are renewing ONE’s strategy with the aim of strengthening the diversity of our expertise, fostering employee engagement, and delivering a client experience built on creative insight. I am very pleased with the direction we have chosen together and with the team that will be responsible for implementing it," says Kari Kauniskangas, CEO of AINS Group.

"It is a great honor to lead ONE Architects. I have had the opportunity to help build and develop this practice alongside an exceptionally talented and versatile team of professionals. Our multidisciplinary expertise, combined with our ability to engage in meaningful dialogue and understand our clients’ objectives from a broad perspective, are among our greatest strengths. This enables us to seize a wide range of opportunities and create solutions that meet the needs of even the most demanding projects," says Tuomas Seppänen.

Four Business Units

ONE Architects is organized into four units: Public, Living, Industry, and Urban & Special Projects.

The Public unit is led by architect Nina Väistö, the Living unit by architect J-P Lehtinen, and the industry unit by architect Juha Lehtonen. Under the flexible operating model, employees will continue to contribute to projects across unit boundaries. Architect SAFA Sami Horto has joined the ONE team on 1 September and takes on the responsibility for leading the Urban & Special Projects unit.

Going forward, ONE leadership team consists of Tuomas Seppänen, Director, EVP; Tapani Eronen, Lead Architect and Helsinki Office Manager; the four Unit Directors; Saara Pynnönen, Business Controller; and Tuuli Törmäkangas, HR Business Partner.

"I would like to wish Tuomas and the entire leadership team every success in their new roles, and I want to thank Jaakob for his leadership of the business in what has been a particularly challenging operating environment. I would also like to warmly welcome Sami Horto to ONE," says Kari Kauniskangas.

The new appointments, organizational structure, and ongoing strategy work were presented today to the ONE Architects team at the Ruoholahdenkatu office.
