Architects NRT has overseen many renovation and expansion projects of historically significant buildings, for instance the main building of the Bank of Finland and the Porthania building of the University of Helsinki. The firm has renovated several buildings originally designed by Alvar Aalto, such as Finlandia Hall, the Kulttuuritalo cultural centre in Helsinki, and many buildings on the Aalto University Otaniemi campus.[1]
History
NRT’s predecessor, Katras, was founded in 1971. Its founding members included architects Pekka Helin and Tuomo Siitonen, as well as Matti Nurmela (1946–2012), Kari Raimoranta (born 1945) and Jyrki Tasa (born 1944), who split from Katras and founded their own practice in 1979. The firm operated as a general partnership (avoin yhtiö) until becoming a joint stock company (osakeyhtiö) in 1993. The office was called Arkkitehtitoimisto Nurmela, Raimoranta, Tasa Oy until 2006, when it was abbreviated to NRT based on the founders’ initials.[4][5]

Awards and recognitions
Architects NRT has won two Finlandia prizes for Architecture: for the Harald Herlin Learning Centre in 2017, in collaboration with JKMM Architects,[2] and for the renovation of the Helsinki Olympic Stadium in 2021, in collaboration with K2S.[3] In 2025 the firm was shortlisted for the prize for the renovation of the Finlandia Hall,[24] and in 2015 for the Merenkulkijanranta housing block.[10]
Two of the firm’s renovation projects have won the Europa Nostra award, the renovation of the Porthania building of the University of Helsinki in 2007[15] and the renovation of Tapiola swimming pool in 2008.[16] The company has been nominated for the Mies van der Rohe Award twice: in 2005 for the Moby Dick House[18] and in 2022 for the renovation of the Olympic Stadium.[25]
Architects NRT was awarded the “Rose for Building” prize (Rakentamisen Ruusu) by the Helsinki City Building Control Commission in 2006. According to the jury’s justification, the firm represented “new and bold ideas both regarding architecture of the exterior and spatial solutions. [... It] has also in an extraordinary way responded to challenges involved with the planning of repairs of high-profile buildings. The unquestioned starting point for the repairs has clearly been respect for the original architecture, and an adequate inventory of the building has been carried out first.“[26]
