In 1960, the township of Salo became a city, which was followed by a change in the look of local architecture: the era of detached wooden houses gave way to the period of modern blocks of flats. One of the earliest changes was the construction of a new and modern block of flats at Inkerinkatu 2 in 1961. The architectural firm of Lauri Hollmén and Jarkko Koski designed an apartment building with windows opening in the direction of Inkerinkatu and the Uskelanjoki river. Its appearance is based on simple horizontal lines and shapes refined from Functionalist architecture. This started a new era with a significant effect on the cityscape: instead of details, the main focus of architecture shifted to designing the entire building mass and its appearance.
