Considered by some to be the most fabulous private home in the world, the Uplands, at that time, was one of 11 Grand Mansions in Hillsborough, some such as The Carolands, equally extravagant in size. Of grandiose Proportions and magnificent architecture, these estates, like The Uplands, were used as summer homes for those who also had mansions in San Francisco. These estates include Villa de Guigne, New Place, now the Burlingame Country Club, Home Place, demolished, Newhall Manor, now La Dolphine, Rosecourt, Strawberry Hill, The Carolands, House on Hill, Armsby estate, and Fagan Estate. Only in such places as Newport, the north shore of Long Island, and the south of France, were there Estates of such grandeur and magnificence.
