51°25′34″N 0°39′00″W / 51.426040°N 0.649894°W Sunninghill Park was a country house and estate of about 665 acres (2.7 km2; 1.0 sq mi) directly north of Cheapside.
The early 19th century house burned down in 1947 and a replacement was built in the grounds during the final years of the 1980s to be the official residence of the Duke of York from 1990 until 2004; it was sold in 2007. The house fell into disrepair and was demolished in 2016.[1]
