Radiolinja’s office block is located in the Keilalahti area of Espoo, next to the buildings of Nokia, Kone and Fortum. Together the buildings of Radiolinja and Kone form a town space arrangement, with the two light, glass buildings standing on a common pedestal, Radiolinja’s building a horizontal and Kone’s building a tower-type mass.

Radiolinja’s office block has a very individual and easily recognisable character. The façades are characterised by transparency, lights and the movement of the panorama lifts. The glass building also reflects an open attitude toward the society, in contrast to the enclosed office blocks.
In the work spaces the objective has been to maximise the amount of natural light, which is by far the best form of light for people’s psychological and physical well-being. The work spaces are designed to be easily adapted to the constant changes of office work. The partition wall systems and the technical systems of the building make it possible to modify the office spaces quickly and at low costs, to meet the requirements of the work at any time. Only the spaces that are always required regardless of the end-user (toilets, cleaning facilities, copying rooms, storerooms and kitchenettes as well as flues, lifts and stairwells) are fixed spaces. All the other spaces can be adapted to the needs as open-plan offices, individual rooms or a combination of these.

The building has eight storeys plus a basement and a roof floor. The building stands ca. 42.0 m tall and provides work space for about 1000 people. Parking spaces are located in the parking garage that forms the joint pedestal of Kone’s and Radiolinja’s buildings. The garage has parking space for 550 cars, both on the roof deck and under the deck.
On
the seaside the building covers street area.
The roof is of steel construction over the lobby, with fireproofing to class R60. The 4.75-m long cantilevered parts at the building ends are supported by tension rods stressed from columns. There are 40 tension rods at each end. The end parts were built on temporary columns, which were then removed after the end line was raised 10-15 mm by stressing the tension rods.
The columns are mainly round steel/concrete composite columns, with reinforced concrete filling cast on the site using pressure casting from the bottom up. The columns connected to the lattice structures are mainly square steel columns.

The office block is separated from the parking garage by expansion joints and divided by expansion joints into three expansion sections, each of which requires its own stiffening structures. The building is stiffened with fireproofed steel stiffening lattices. There are three lattices in each end expansion section and two lattices in the middle expansion section, located crosswise to the frame. Each expansion section has also one stiffening lattice located longitudinal to the frame.
