Oakland was incorporated as a town in 1852 and re-incorporated as a city two years later, then spread east and north as neighbouring districts joined it; in 1909 Elmhurst, Fruitvale, Melrose, Fitchburg and Claremont voted to annex. Rockridge went on sale in 1906, when the Laymance Real Estate Company divided it into Rockridge Place, Rockridge Park and Rockridge Terrace, and most of its houses were built over the following two decades. Above the lake, Crocker Highlands was laid out on winding streets that follow the contours of the hills, and Montclair's hillside subdivisions began in the 1920s on the western slope of the Oakland Hills. Homes from those years were drawn up around far fewer clothes than a household owns today, and closing that gap is the starting point for every design here.
