Architect SAFA Sami Horto has been appointed Lead Architect at ONE Architects as of 1 September 2026. Known as a visionary developer of the architectural profession, Horto takes responsibility for the multidisciplinary office’s Urban & Special Projects unit.
Having previously served as a founding partner of ARCO Architecture Company and most recently as Director of Development at Lundén Architecture Company, Horto brings together architectural expertise, business acumen, and extensive experience in the long-term development of organizations.
"Sami is an outstanding architect and an exceptionally strong expert in real estate development and complex projects, in many ways a true wizard of property development. He has a unique ability to drive forward complex initiatives and turn ambitious ideas into reality” says Tuomas Seppänen, Director, EVP.
"ONE Architects offers the best platform in Finland to respond to the evolution of the architectural profession, where information and data are transforming the architect's role. The purpose of data is not to replace people, but to help us make better and more far-reaching decisions and direct creativity toward the right challenges. The best ideas are often born from constraints and compromises. ONE is home to an exceptionally intelligent, open-minded, and positive group of people, and joining the company feels a little like coming home," says Sami Horto.
We work across a wide range of projects, from residential buildings and hotels to hybrid developments, renewable energy, industrial projects and specialized facilities such as hospitals and arenas. As the built environment becomes increasingly complex, our multidisciplinary expertise allows us to take on diverse and demanding projects.
"If we want to deliver truly demanding projects, versatility is not an added benefit, it is a necessity," Horto concludes.
