The new Oulu Courthouse, a collaboration between PES-Architects and Komulainen Arkkitehdit, involves a new building on Torikatu and an extensive renovation of the existing building towards Sepänkatu. The courthouse complex unites most of the local and regional courts and judicial administration under one roof, with courtrooms, customer service facilities and offices for around 400 staff. The building provides a safe, healthy and secure environment for its users, with a special focus on the quality of indoor conditions and acoustics.
