The first changes to the ground took place in 1931, when the corner between the Main Stand and the Platt Lane end at the south of the ground was rebuilt to incorporate a roof. The highest attendance at an English football game of any type at a club ground was at Maine Road on the March 3, 1934, when Manchester City played Stoke City in front of 84,569 fans in the 6th round of the FA Cup. Changes at the Platt Lane end took place in 1935, extending the terracing and providing a roof for the full stand. This marked the peak capacity of the ground, estimated at around 88,000. Further changes were planned, but were suspended when Manchester City were relegated from Division One in 1938, and abandoned when World War II broke out.
