From the 1960s onwards Ashford has experienced phases of rapid urban growth, creating new suburbs such as Stanhope and, more recently, Singleton. Today's urban growth is partially shaped by the "de facto" corridors created by the M20 motorway, the High Speed 1 line and several other rail lines which converge on the town's railway station; this has contributed to particular development pressure on, and the development of, greenfield sites in and adjacent to the town, especially, but not exclusively, to the south and west—for example at Sevington.
