The facilities are owned by the Municipality of Oslo and used and operated by Grüner IL, the local sports club.[8] In 1985, artificial ice was laid north of the football pitch, costing 2.1 million Norwegian krone (NOK).The club therefore hired Einar Dahle Arkitekter to work on a new design, resulting in area planning regulations being passed in 1991.[10] In 1994, the municipality initiated a redevelopment program of the downtown residential areas, which included grants to build Grünerhallen.[13] Dælenenga idrettspark consists of a club house, an artificial turf football pitch and an indoor ice rink.The venue is owned by Oslo Municipality, but the day-to-day operation is undertaken by Grüner IL, the main tenant.The building has suffered under lack of maintenance and has been subject to water damage, although the outer walls and foundation are in good condition.The club house has an impractical floor plan, and contains gyms for martial art and changing rooms for the pitch.[10] Dælenenga idrettspark is 1.5 kilometers (1 mi) from downtown Oslo and is located on Ruter bus route 30[16] and close to the light rail station Birkelunden on the Grünerløkka–Torshov Line.[17] During the late 1920s and 1930s, Dælenenga was dominated by the Workers' Sports Federation (AIF) and served as its main stadium in Oslo.The route ran through various streets in eastern Oslo and was a counter-measure to Holmenkollstafetten in the western part of town.The most notable regular local drivers were Basse Hveem, Henry Andersen, Werner Lorentzen and Aage Hansen.
