As the tithe map of 1847 shows (see local maps), Starrock Farm was independently owned by George Harrison. This was one of the smaller farms in Chipstead, with land on both sides of Starrock Lane. The mansion of Starrock Court was added in 1868. Starrock Court is unusual in that it is almost entirely constructed of flint, on a flint foundation, the stone presumably being mined locally. Four storey accommodation for servants was added to the main house in the 1880's.
The Ross family owned Starrock Court during World War I, and the family could observe the bombing of London by Zeppelin airship raids from the belvedere on top of the house. Sadly, the Ross family lost 3 sons and a daughter in the war, which is recorded on the war memorial on Church Green.
The north western part of Starrock Farm, bounded by High Road, Coulsdon Lane and Starrock Lane, was developed as residential housing between the wars. However, the south eastern part continues as a working farm, although the original farmhouse is now a private residence.
