What UKI Arkkitehdit does

UKI Arkkitehdit is a Finnish architecture and design firm headquartered in Oulu, founded in 1958 and family-owned by the Heikkinen family across three generations. The firm employs approximately 100 design professionals across four offices in Oulu, Helsinki, Jyväskylä, and Rovaniemi. UKI provides architectural, interior design, and master-planning services with particular depth in healthcare facilities, industrial complexes, and public-sector buildings. Its client base includes major Finnish hospital districts (PPSHP, HUS, TAYS), industrial operators (Metsä Fibre, SSAB), and infrastructure projects spanning nuclear power plants, bioproduct mills, and airports.

The firm operates a fee-for-service consulting model typical of professional services, with revenue tied to long-duration project engagements measured in gross square meters (brm²). UKI's core technology stack centers on BIM (Building Information Modeling) coordination and its proprietary VALO® evidence-based design method, which integrates CAVE (Cave Automatic Virtual Environment) virtual simulation for immersive stakeholder review. The firm has developed sustainability expertise including life-cycle assessment and carbon footprinting, and holds EcoCompass (2022) and RALA quality certifications. It is a founding member of Green Building Council Finland, positioning sustainability as a differentiator in EU-aligned public tenders.

UKI has pursued growth through geographic expansion into international markets (Belgium, France, England, Scotland, Uruguay, Poland, Turkey) and inorganic consolidation, acquiring multiple Finnish firms during the 2010s including Matti Onkalo Oy, KKS, Juhana Romppainen Oy, Arknova Oy, and Laatio in 2021. The firm nearly tripled revenue between 2010 and 2019, establishing itself as a specialist in complex healthcare and industrial infrastructure projects. In August 2024, the firm appointed Ulla Passoja as CEO, with founder Mikko Heikkinen transitioning to Chairman — signaling a transition to professional management while retaining family ownership.
