Municipal office buildings of Kallio

Invited competition

We designed a versatile building complex for the plot in Kallio neighbourhood that will open for new use once the old municipal buildings are demolished. The block’s new center, Kalliontori Plaza, is surrounded by offices, apartments, restaurants and a hotel. An entrance was added to the metro and the “Pisara” railway station.
