The house stands close to Stanmer village and Church, within Stanmer Park. Constructed by the French architect Nicholas Dubois in 1722 in a Palladian style for the Pelham family, it incorporates the remains of an earlier house, and was again altered in 1860.
The house and park were bought by the local authority in 1947. The building was designated as Grade I listed in 1954; the former stables, built c. 1725 but much altered, are Grade II* listed.
Close to the University of Sussex campus, the house was used as a university administration building for some years in the 1960s while the campus was being built in the eastern portion of the park. After undergoing extensive renovation, it reopened in June 2006 and for use as a restaurant and events venue.
In 2009, the Willkommen Collective started a music festival at Stanmer House. The first event featured performances from The Leisure Society, Alessi's Ark, Peggy Sue and more in Stanmer House and grounds. The second festival took place on 12 September 2010 and was named Foxtrot. The lineup included Laura Marling, Anna Calvi, Francois & the Atlas Mountains and Sons of Noel and Adrian. The third annual festival took place in September 2011 and featured Herman Düne, Sam Amidon, This Is The Kit and more.
In January 2020, Proud announced that Stanmer House would close to the public as the company entered liquidation, stating that a rent increase was to blame. However many people criticised the venue under his company's operation, stating that it was poorly run.
KSD Group, run by three local businessmen, took back the commercial lease, and reopened the café for Easter 2021. Planning permission to convert the house into a hotel is in place, but KSG is uncertain if it will proceed with this plan.
