up a work committee aimed at making AB a pitch owning club like neighboring club Københavns Boldklub and B93 had just become. The committee collected DKK 60,000 for the financing of the facilities, which came primarily from interest free bond loans from supporters of the club. In autumn 1902, the club rented six acres of land at Lammefælleden on Østerbro in Copenhagen by Copenhagen Municipality for the establishment of the new training facilities, which was put into service already in 1903. Shortly after the establishment of the new training facilities, AB also got a new home ground. Interest in sports was increasing in the early 19th century, and for this reason, the mayor of Copenhagen Jens Jensen in 1906 presented a proposal for the establishment of a sports park, which was granted DKK 1,264,450 for the construction of. In 1911, Københavns Idrætspark was completed and the facility became home to the Danish national team and several Copenhagen football clubs, including AB. AB's football game developed drastically as the club went from the uneven grounds they had played on so far to good fields on the new facilities.

A highlight in the period after moving to Østerbro was when the team played 2–2 against professional Middlesbrough F.C. from England. In 1912, the poor results reached a new low point when AB ended last in the domestic tournament and had to play a relegation match against Østerbros Boldklub. AB won the relegation match 3-1 and was thus rescued from relegation. In the 1910s, the results began to improve again, and in 1914, AB participated in its first Copenhagen Cup final, but lost 3–4 to KB. In 1919, the luck eventually turned when AB won its first Danish Championship after defeating B 1901 3–0 in the final. KBU's tournament, which led to the final of the Danish domestic football tournament, was won in a convincing way with 11 wins and only one defeat and a goal score of 46–16. In 1921, AB again won the Danish Championship when AGF was defeated 3-0 by a team consisting of many of the same players who had won the championship two years earlier. During the years on Østerbro, AB and BK Frem collaborated on arranging so-called "English matches", as KB and
