 Also, in the BePOP shopping centre (1989), Pori, by Nurmela-Raimoranta-Tasa architects, for all its idiosyncratic postmodern interior and curved "medieval" street cutting through the building, the overall urban block still fits within strict height parameters for the area.The Kankaanpää public office centre (1994) by architects Sinikka Kouvo and Erkki Partanen applied a "heterotopic" ordering – clashes of different volumes – previously discernible in the mature work of Aalto but with a postmodernist twist of Mario Botta-esque "round houses" and striking striped bands of brickwork.The aims at a new understanding of regionalism yet in a modern idiom materialised in the greater use of timber – the building material most associated historically with Finnish architecture.
