The Small Mansion - Gunnersbury House, Gunnersbury Park, Gunnersbury Avenue W3 - Hounslow

Built circa 1802, the smaller of the two houses on the site of Gunnersbury House which was demolished circa 1801. Historic England has funded a condition survey to inform potential repairs to stabilise the building. The ground floor has recently been used as offices but this use is due to cease. The Local Authority, Historic England and other stakeholders are working proactively to identify and secure a new user to complete necessary works and fully occupy the building.
