[7] When a merger of the municipality's three largest sports clubs was considered in the 1950s, much suggests that these plans were fostered on a political as well as executive level.

Its proponents saw obvious advantages in a merger, which would mean that administrative personnel and athletes would have better physical surroundings to exercise and compete, and finally it would benefit both horizontally and vertically that all energy would become gathered in one club.

[3] Conditions around the main playing pitch were also improved; in 1966 two turnstiles were set up at the stadium entrance,[14] and in 1969 a clock was added, courtesy of local watchmaker Bent Henriksen from Brøndbyøster Torv.

[15] Only in 1977, when the club reached promotion to the third highest football league in Denmark, the Danish 2nd Division, did the municipality decide that a covered grandstand should be erected.

[16] The stand, which could hold 1,335 seated spectators, and included a speaker booth, media facilities and a TV plateau, was placed facing West towards Gildhøjskolen.

[15] As Brøndby IF had reached promotion to the highest football league in Denmark in the fall of 1981, then known as the 1st Division, mayor Kjeld Rasmussen proclaimed that a covered stand would be constructed.

However, this was solved by installing temporary end stands of scaffolding, which allowed the club to receive an approval by the UEFA to organise the home leg against Torpedo Moscow.

[23] As Brøndby IF gained domestic and European success, spectator interest had grown to such a degree, that it became necessary to move the biggest matches to Københavns Idrætspark.

[25] Despite improved spectator facilities, the stadium did still not live up to UEFA requirements,[27] and the club wished to erect permanent terracing behind both goals.

[25] Brøndby IF had meanwhile offered to pay for construction costs of the end stands themselves, but in order to do so the pitch had to be expanded both in width and length.

In December 1991, the contractor began removing the running track,[29] and in the spring of 1992, the expanded Brøndby Stadium has reached completion: four covered stands with a total capacity of almost 21,000 spectators.

[30][31] This included the infamous terraced "South Side"-end (Danish: Sydsiden) – then known as Faxe Tribunen for sponsorship reasons – which was inaugurated on 29 March 1992.

[27] This resulted in losses; both on a financial level, but also in terms of prestige, and because of this the board continued to work on plans of further expanding the stadium.

[36] These would – together with the existing lower stands – ensure that the stadium could bring the total spectator capacity to more than 30,000 for European games and 33,000 to domestic matches.

[38][43] The first competitive game after the rebuild occurred on 22 October 2000 with a 4–2 league win over Akademisk Boldklub in front of 28,416 spectators.

[38] The redevelopment also made Brøndby Stadium a part of the Nordic countries' bid for hosting the UEFA Euro 2008, which was eventually awarded to Austria–Switzerland.

[45] Because the total costs of the 1999–2000 expansion exceeded the originally planned budget by DKK 30–40 million, some major and minor additions and improvements to audience facilities were postponed and subsequently carried out over time.

[40][42] First of foremost, the club could not afford new turnstiles, and a planned, highly modern entrance system was only installed in 2003, just as the scoreboards initially did not meet the requirements of the Danish Football Union.

[53] In addition, each gable was adorned with four large images that showed Brøndby IF players and fans in different situations.

[53] During the winter break in of the 2017–18 season, the hole on the South Side-end was closed which meant that an additional 75 seats and extra capacity for 150 standing spectators on terracing were added to the stadium.

[56] The Brøndby Stadium pitch is surrounded by four covered stands, officially known as Sydsiden (South), GSV-tribunen (East), J. Jensen-tribunen (North) and Carlsberg-tribunen (West).

[58] This would mark the beginning of a hard-core fan-culture formation on Sydsiden, which has remained ever since, and it is known as the stand in Denmark with the most dedicated and loudest fans when Brøndby plays its home games.

The fanzone is the first of its kind in Scandinavia, and consists of stands for live concerts, bars, foodstands and toilet facilities.

[60] Sydsiden popularised the "Fenerbahçe greeting" in Denmark, imported through the transfer of Brian Steen Nielsen to the Turkish club.

[58] A cooperation between goalkeeper Mogens Krogh and Brøndby Support effectually made the greeting get foothold in Denmark.

In 2006, a larger extension was established behind the stand from the facade, consisting of sponsor facilities, a sports bar and classrooms for Brøndby Gymnasium.

[3] Due to insufficient training grounds in the early years of Brøndby IF, the grass on the pitch quickly became worn, and in 1971 so many holes had appeared that it needed to be relaid.

[72] In addition to the improved pitch, new floodlights were installed on the roof of the west and east stands,[20] in order for the lighting to meet the international requirements.

In 2015, the grass playing surface had not been replaced since 1997,[73] and was four times as old as the four-year-old green turf at Blue Water Arena in Esbjerg, which at that point made it the second oldest pitch in the Danish Superliga.

A solution at the cost of DKK 1–2 million with turf from the Netherlands was chosen, which would constitute a temporary pitch before a major renovation was to be completed in October.
