Tietoevry Keilalahti Campus/Microsoft Talo (formerly named Nokia House) is the head office building of Tieto[1] and Microsoft Finland,[2] located in Keilaniemi, Espoo, just outside Helsinki, the capital of Finland.
History
The campus was built between 1995 and 1997 as headquarters for Nokia by architect Pekka Helin. It comprises three separate structures: The two most southern parts of the building were built in the early 1990s and the third, most northern part was built in 2000.[3]
Nokia operated in the building from 1997 to 2014, with around 5000 employees working in the premises. They owned the building up until December 2012, when it was announced that it had been sold to Finland-based Exilion for €170 million. Nokia continued using the building as its head office, leasing it on a long-term basis.[4]
