In conjunction with the stadium is the head office of many sports federations, a bandy field, and commercial property including a conference center, hotel and shopping mall.

Plans call to replace the West Stand to increase capacity to 30,000 and perhaps add a retractable roof and artificial turf.

[2] The club made an agreement with the tram operator Akersbanerne to purchase land they had acquired as part of the construction of the Sognsvann Line.

The match against Sweden from the Nordic Football Championship 1933/36 on 22 September 1935 was held in front of a crowd of 35,495, which still stands as the spectator record.

Other activities held during the first decades included boxing, and a revival meeting hosted by Billy Graham in front of 40,000 people in 1955.

The costs were covered by Sogn Næringsbygg, who built the stands and then received free ground to build 12,000 square meters (130,000 sq ft) of commercial real estate.

[9] On 14 June 1987, Ullevaal was the host of the final of the 1987 European Competition for Women's Football, where Norway beat Sweden 2–0 in front of 8,408 spectators.

[12] The renovations included a new turf with under-soil heating, luxury boxes, VIP-seating, a section for the royal family, new change rooms and 5,000 square meters (54,000 sq ft) of restaurant and meeting area.

[16] To create additional liquidity, the club sold its 44% share in Ullevaal to the Football Association for NOK 4.4 million in January 1993.

The federation hoped to use the high incomes generated from the recent success of the national team, including from participation in the 1994 FIFA World Cup, to allow the stadium company to charge high rent for the international matches and Cup Finals, thus quickly eliminating the stadium's debt.

NFF felt it was unfair that they were in practice subsidizing Lyn by not having similar rent increases for the club, and that this should be reflected in the share value.

[1] On 12 July 1997, Ullevaal was the host of the final of the UEFA Women's Euro 1997, where Germany beat Italy 2–0 in front of 2,221 spectators.

[31] The project also included 44,000 square metres (470,000 sq ft) of commercial real estate, to be located behind the south stands.

[34] The Norwegian Football Museum was established and received 250 square metres (2,700 sq ft) in the southern stand building.

Although they stated that they had a better economic proposal from Ullevaal, the team stayed at Bislett to have more influence on the design of the new stadium that would replace the existing structure.

Oslo's other Premier League team, Skeid Fotball, stated that they had also considered playing at Ullevaal, but wanted to keep the more "intimate feeling" at Voldsløkka Stadion.

Prior to the 2000 season, Vålerenga signed a three-year contract with Ullevaal, making the national stadium their home.

This made it possible for Lyn to pay their investment company back the debt for the loan, which had increased to this amount in five years, and to purchase the stadium and secure NFF the right of pre-emption.

[45] On 23 March 2007, NFF bought Lyn's remaining 13.07% share of Ullevaal, securing the federation full control of the national stadium.

[46] Following Lyn's relegation from the Norwegian Premier League after the 2009 season, the club decided to move its home games from Ullevaal to Bislett.

[50] In a 2012 survey carried out by the Norwegian Players' Association among away-team captains, Ullevaal was found to be the league's best stadium, with a score of 4,47 on a scale from one to five.

[51] Vålerenga had long stated that they wanted to relocate and had conducted plans to build a new stadium at Valle Hovin, where the club currently have their administration and training facilities.

Vålerenga were playing in Eliteserien until being relegated after the 2023 season, whereas Lyn went bankrupt in late 2010 and were moved to tier 7 (6. divisjon) and worked their way up through the divisions.

There are similar facilities in the North Stand, allowing a television team from the opposing nation to make a double production.

[60] Several other international artists has also performed there, including Rammstein, Kygo, Green Day, Bon Jovi and Bruce Springsteen.

The stadium is also within a ten-minute walk from Rikshospitalet station of the Oslo Tramway, located on the Ullevål Hageby Line and served by trams 17 and 18.

[64] Commentators have stated that among older footballers there is opposition against artificial turf, but that long Norwegian winters cause pitches to be extremely bad during the early parts of the season.

In 2010, seven of sixteen premiership stadiums used artificial turf; commentators have stated that if Ullevaal converted, it could be a pivoting point for other clubs to do the same.

Inspired by the new Friends Arena to be built in Stockholm, a new venue would have a capacity for 52,000 spectators and was part of the joint Norwegian–Swedish bid for UEFA Euro 2016.

NFF stated that expanding Ullevaal beyond 31,000 spectators would be excessively expensive and that the location poses limitations in transport infrastructure to handle so large crowds.
