Knockroon is a planned development located between the towns of Cumnock and Auchinleck in East Ayrshire, Scotland.

East Ayrshire Council granted outline planning permission for 770 houses on 7 December 2009.

[1] The development of Knockroon was expected to continue over a 25-year period, backed by The Prince's Foundation for the Built Environment,[2] and is being designed on green principles.

A leading Scottish architect, Professor Alan Dunlop, described the prince's vision as an "imported pastiche" and a "curious mix" of relatively expensive homes dropped into a rural setting that should have never been built.

[6] In July 2022, a spokesman for the Office of the Scottish Charity Regulator said "we can confirm that the work of Havisham Group and property transactions relating to the Knockroon development in Ayrshire forms part of our overall investigation, work on which is ongoing.
