Urban Eden is a pressure group based in Milton Keynes, England, formed in 2006. The group states that its aim is to "promote a sustainable expansion to the original masterplan for Milton Keynes". In recent years the expansion of Milton Keynes has moved away from the original design principles of the city; Urban Eden campaigns against this trend, pressuring for new developments to remain true to the original vision for the new city. As of 2009 the group says that it has over one hundred members, including a number of professional engineers and town planners, as well as some former employees of the Milton Keynes Development Corporation.
