The formal gardens and a large area of woodland came into public ownership after Holland House was bombed during the Second World War. The park is now open to the public. It's spatial qualities were analysed by Dame Sylvia Crowe in her book 'Garden Design' (she lived nearby). A Japanese Garden was opened in 1991. Nearby, one can see the Commonwealth Institute with its grounds designed by Dame Sylvia. Flagpoles, an avenue of lime trees, a fine water feature and good paving provide an impressive setting for an international building. The eighteenth century planting by Charles Hamilton has gone.
