Holwood House is a 25,060 square feet (2,328 m2) country house in Keston, near Hayes, in the London Borough of Bromley, England. The house was designed by Decimus Burton, built between 1823 and 1826 and is in the Greek Revival style. It was built for John Ward who later employed Burton to lay out his Calverley Park Estate in Tunbridge Wells. The gate lodges of that estate take their names from the gate lodges on the Holwood Estate - Farnborough Lodge and Keston Lodge.
