The mansion which forms the main school was built in 1846 attached to an existing farmhouse and was a private family home. It was designed by the eminent designer and architect Augustus Welby Pugin for Captain Washington Hibbert, and is a Grade II* listed building. The first pupils were brought to the house by The Reverend Walter Earle in 1887. The brewhouse was converted into the school chapel in 1889 and classrooms were added in 1892.
The school formally amalgamated with the neighboroughing Homefield Girls' School, with which it had long had a connection, in 1992 with Bilton a Grange becoming co-educational and the Homefield School building becoming the Pre-Prep department for children aged 4 to 8.
