Accountor Tower

The tower has twenty floors overground and two floors underground, and its height is 83.6 metres. The total floor surface area of the building is 25,444 square metres. The facade of the tower is built of white limestone from Sipoo and the windows have a blue tint. The cross section of the tower is rectangular in shape, and both ends of the rectangle shape have parts extending outward from the main mass. Most of the office floors consist of open office spaces, with the tower having enough office space for over one thousand workers. The base of the tower includes a lunch restaurant and exercise spaces. Next to the tower is a three-story high additional building called Keilalampi, built in 1994. It is built of steel and has a cone-shaped glass roof. The Keilalampi building was designed by the architect bureau CJN, the successor to the architect bureau Castrén-Jauhiainen-Nuuttila. ==History==

Construction Construction of the tower started in 1974 and it reached its full height in 1975. The building was completed in 1976 and taken into use on 7 October in the same year. In 1994 Neste expanded its head office by building a lower expansion building called "Keilalampi" next to the tower, giving it the official name Valovirta. The Fortum Retirement Foundation owned the tower as well as the Keilalampi building, while the four lots in the area were owned by Fortum. In 2018 the plan to convert the building into residential use was abandoned. The financial software company Accountor moved into the premises in late 2019. At the same time the building was renamed as the Accountor Tower. In spring 2020 Hewlett Packard Enterprise moved its Finland head office to the Accountor Tower. ==See also==
