The club started to develop the ground in the 1920s, with banking created and a new 300-seat stand installed on the western side of the ground in 1922 at a cost of £250. With the extension of the roof, the seating capacity was later increased to about 400. However, players still changed in the nearby Horse and Groom pub. A covered terrace was installed in 1930 and dressing rooms built the following year. Another covered stand was installed at the Ford End Road end of the ground in 1935, which was replaced by a more modern stand in 1953. The capacity had reached at least 6,000, and a new record attendance of 5,667 was set for the FA Cup match against Dartford in 1934–35. The roof of the stand built in 1930 was destroyed in late 1938 and was replaced by the start of the 1939–40 season. Further ground developments in the 1950s raised the capacity to 18,500, with the record attendance of 18,407 set for an FA Cup game against Everton in 1965–66.
