Ascot House, Historical residence in Newtown, Toowoomba, Australia.

Ascot House is a large timber residence in Toowoomba featuring a single-story main section and a two-story addition, both adorned with decorative cast-iron details and verandahs. The structure reflects the spacious living style preferred by the region's wealthy residents.

Frederick Hurrell Holberton, a local merchant and Legislative Council member, built the house in the 1870s on a large estate near the racecourse. William Beit Jr. later added a significant extension that altered the character of the residence.

William Beit Jr. is thought to have named the house Ascot because of his interest in horse racing. The two-storey extension he added in the 1890s, designed by Toowoomba architect Harry Marks, became known as Beit's Folly. Since 1994 the folly has housed a tea room and house museum.

The two-storey folly, Beit's Folly, opened as a tea room and house museum in 1994 after renovations by the owner who bought the house in 1984. The folly is entered from the rear of the house, while internal access comes from the end of the central hallway. The property now covers just over 2 acres of the original 32-acre estate.

The extension added by William Beit Jr. in the 1890s is locally known as 'Beit's Folly' and features elaborate facades with intricate details. This unusual addition surprises many visitors with its artistic architectural elements.
