allowed this part of the site to be dated to the 11th century. However, the castle is believed to have been built around 1066 then either demolished or changed significantly as it does not appear as a castle in Domesday Book. The farm buildings date back to the 13th century with the Great Barn the most prominent. The barn is the second largest such structure in Middlesex after another in Harmondsworth. The Great Barn is constructed of English oak from the nearby Ruislip Woods. It was built to a design known as an aisled barn, whereby smaller out-shoots run alongside the main supports underneath one main roof. Ownership Studies by English Heritage have found that the site originally functioned not only as the manorial court hall for Ruislip, but also as a working farm. The main building was built over two existing structures, possibly to accommodate the new lessee of the manor, Robert Drury, a former Speaker of the House of Commons. The study concluded this was most likely achieved by a team of masons and carpenters. Manor Farm was also known as Ruislip Court until the 19th century. In 1451, ownership of the farm passed with the rest of Ruislip to King's College, Cambridge who remain titular Lords of the Manor. King's completed two surveys of the manor during their ownership, in 1565 and 1750. The Farm House was built from locally produced bricks, tiles and timber in the 16th century, and served as the manorial court until 1925 when the last court was held. Work in the 18th and 19th centuries saw the windows and doorways replaced, while an extended kitchen was installed. The kitchen extension was replaced in 1958 as part of a general refurbishment of the house. Manor Farm and Park Wood were nearly demolished in the early 1900s to make way for a new development planned in partnership with King's College and the Ruislip-Northwood Urban District Council. A town planning competition was won by A & J Soutar from Wandsworth, who suggested a symmetrical design across the parish which would have seen a total of 7,642 new homes built. St. Martin's Church would have been the only example of historical architecture left in Ruislip. An outline map of the new development proposal was made public on 30 November 1910 with few objections. A Local Board inquiry followed on 17 February 1911 which required negotiations with
