During the 1920s, the exhibition grounds were expanded to the west and to the east, as well as to the south, where reclaimed land was used to build Lake Shore Boulevard (originally "Boulevard Drive"), connecting downtown with Toronto's growing western suburbs. The Coliseum, to host the new Royal Agricultural Winter Fair, was opened in 1921, followed by the Government of Ontario Building in 1926, the Princes' Gates in 1927, and the Electrical and Engineering Building in 1928. By the 1930s, the Beaux-Arts style faded in popularity. The start of the trend for a new style of architecture arguably became evident in the construction of the Automotive Building in 1929, the first building that moved away from the Beaux-Art architecture envisioned by the 1920 plan, mixing clean modern lines with classical ornamentation. In 1931, the Horse Palace was built, replacing temporary stables used for the Winter Fair. The Horse Palace used Art Deco ornamentation. In 1936, the Art Deco Bandshell was constructed for open-air music concerts.
