A new town created on the eastern edge of Greater London, Thamesmead reflects all the principles of mid-20th century design, creating a built environment that looked like nothing that had come before: urban style in almost rural surroundings; a vision of the future. Our walk will focus on the parts of Thamesmead that most closely reflect the original visionary plan: long blocks running through open green space, terraced houses around landscaped courtyards, the views of tower blocks across Southmere Lake that have become the town’s defining image and the lakeside location -- if planned demolition works permit -- of the violent scenes in the cult film A Clockwork Orange which sealed Thamesmead’s reputation -- for better or worse.
