Hubbard had Addington Manor, at Addington, Buckinghamshire, built to a design by Philip Charles Hardwick in 1856–7. Its site was near the earlier Addington House, which had belonged to John Poulett son of Vere Poulett, but had fallen into disrepair. Hubbard bought the estate there in 1854. The landscape architect William Andrews Nesfield was brought into a planning process from about 1855. The new building was in a French style with a large conservatory. Hubbard demolished part of the old house in 1857. He retained his London house, 24 Prince's Gate, South Kensington opposite Hyde Park.
