Painter and draughtsman, born in Curry Rivel, Somerset. He attended Camberwell School of Arts and Crafts under Anthony Eyton and Euan Uglow, then worked as a copyist for Sotheby’s and Christie’s for three years. In 1980 Warrender began his series of bird’s-eye views of houses, estates and townscapes. Working on commission, he normally did about two a year only. He would make a series of long walks around the subject, would make notes and sketches of the lie of the land and would supplement this information with an owner’s perceptions of the property to be depicted. Having lived in Scotland from the age of 12 Warrender came to paint a number of properties in this area, including Innes House, Elgin; Dunphail House, Forres; Cawdor Castle, Nairn; and The Old Kirk, Altyre, Forres.
