Coulsdon is a place in the London Borough of Croydon on the Brighton Road (A23). The received pronunciation is "Cools-don".
Part of Coulsdon is the estate marked on maps as Clockhouse but always referred to locally as The Mount after its central road. Administratively The Mount is part of the London Borough of Sutton but to reach the rest of Sutton from The Mount by road one must leave the borough. The village lay within the Anglo-Saxon administrative division of Wallington hundred. Couldson appears in Domesday Book as Colesdone. It was held by Chertsey Abbey. Its domesday assets were: 3½ hides; 1 church, 7 ploughs, woodland worth 3 hogs. It rendered £7. Unlike Purley, Coulsdon has managed to retain a good mix of traditional high street shops. It also has a large number of restaurants for its size. ince 2005 there has been a large empty space in the middle of Coulsdon following the demolition of the Red Lion public house. Current (Nov 2007) plans for the site are for an Aldi supermarket. There is also a scheme to replace the Pinewood garage site near Smitham station with a branch of Sainsbury's. Controversy surrounds both projects, mainly because of the large - six storey - scale of these developments and doubts about the need for yet more supermarkets in the area. (There is a Waitrose across the way from the planned site for the Sainsbury's. Recently the Coulsdon branch of Co-op shut down, due presumably to lack of business. Planning consent is being sought to turn it into a pub. One of the largest Tescos in the country is at Purley Cross, a mere mile or so away from the centre of Coulsdon.) More on Coulsdon
