The evolution of Finnish architecture is most clearly manifested in the nation's residential projects, especially social housing, the most regulated form of building construction. The design of these structures is influenced not only by local traditions, urban planning, codes, and financing, but also by the culture of the Finnish people. For instance, Finns expect saunas to be built into all housing units, even small apartments.
Designed by Helsinki-based Heikkinen-Komonen Architects, the new Flooranaukio Housing project in the Arabianranta area of the Finnish capital is mixed-income social housing. Seventy-four of the units are government-subsidized rental apartments, and the other 48 are city-price-controlled owner-occupied housing under Helsinki's HITAS development scheme, which seeks to provide reasonably priced, high-quality housing in the capital. The average sale price runs from about $435 to $500 per square foot, with a starting price equivalent to about $259,000. While the residents of Flooranaukio–Finnish citizens with an average monthly income of $4,000 and a rent of about $1,350–are representative of typical inhabitants of the city, they get the extra benefit of living in a home with a strong connection to its history.
