 Under the leadership of the late Gudmund Jørgensen, the training facilities and the exhibition ground was renovated and expanded in the late 1970s to be able to house the professional department of Herfølge BK, which occurred in advance of the club's promotion to the top league in Denmark in 1980.The stadium's first proper grandstand with seatings, a traditional single tier, was constructed along the western long section in 1986 at a cost of approx.DKK 6 million, which was privately funded after the local municipality would not make the investment, but instead gave the club a 50-year "rights of usage"-agreement for the exhibition field at the stadium.
