 A full upgrade of the station was carried out in 1987 . A main incentive was that the Norwegian Public Roads Administration wanted the station building removed to make room for a new interchange towards Jar . Therefore , Kielland 's station building was demolished in 1987 . The new station building , designed by NSB Arkitektkontor and Arne Henriksen , was built in glass and concrete with a dominant portal presenting the staircases . On the island platform a new ticket booth was built in steel and glass . The platform was covered by a roof of laminated wood and plywood held up by galvanized steel columns . The roof followed the shape of the curved platform and featured a gable .
