Know Where:
West Park hospital lies on the boundaries of Epsom, Ewell and Kingston-upon-Thames in Surrey. The map here shows you the layout as it is today (or was if you are reading this as of 2011). Just an interesting side note about Hollywood Lodge in the bottom right-hand corner. It was owned by the Surrey Epsom and Ewell Department of Health and this building no longer exists due to a fire back in Feb 2005.
The red marked blocks were ones currently in use at the time of the upload in Jan 2008, now none of it is in use.
