From its establishment in 1967 to its abolition in 1992, the Milton Keynes Development Corporation created by far the largest and thus most ambitious of the British new towns. Many of Britain's most acclaimed building and landscape architects contributed to what was to be a showpiece of British design. Unlike previous new towns, Milton Keynes has a majority of privately funded development but, during the MKDC years, these developments were subject to an exacting design brief in line with the design principles laid out in "The Plan for Milton Keynes" .
