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

Built circa 1802, the smaller of the two houses on the site of Gunnersbury House which was demolished circa 1801. The house has been deteriorating rapidly. The Local Authority, Historic England, Gunnersbury 2026 Community Investment Company and other key stakeholders secured significant funding, including from Highways England and Historic England, which has been used to undertake extensive investigative works and urgent repairs.
