 If the minimalism of the "rationalist school" could be equally inspired by the works of the modernist masters Le Corbusier and Ludwig Mies van der Rohe as the machine aesthetic of Russian Constructivist architecture or the machine futurism of Buckminster Fuller, there were also allusions and references to cultural precedent, equally Finnish peasant dwellings and Japanese vernacular architecture.This attitude could also indeed be seen as falling under the Structuralist outlook of that time, as evident also in Japanese modernist architects such as Kenzo Tange, and in the parallel architectural phenomenon of Brutalist architecture (a reference to the British architectural style from the same period).The main exponent of this style was Aarno Ruusuvuori, with the heavy use of concrete as an aesthetic; e.g., Huutoniemi Church, Vaasa (1964), Tapiola Church (1965) and the Weilin & Göös Print Works, Espoo (1964–1966; converted into the WeeGee Exhibition Centre, 2006).
