Sir David Duncan of the Mackintosh family, famous for ‘Mackintosh toffee’, built the manor in 1932. He used an architectural design of a Scottish hunting hotel – the west side had a view of Ngong Hills while the south side had a view of Mt. Kilimanjaro. At the time, the manor was on a 150-acre piece of land. He sold it in the 1960s, and the new owner leased it repeatedly until it fell into disrepair.
