 A report had been prepared for the parish council in 1903 which noted the population in Northwood – 2,700 by that time, with 530 houses – compared with the largely rural character of the rest of Ruislip parish. At a meeting of the Ruislip parish council on 28 October 1903, the forthcoming extension of the Metropolitan Railway from Harrow on the Hill to Uxbridge was also discussed as it was known that a station would be opened in Ruislip on the new line. Councillors were also aware that King's College, Cambridge, owners of much of the land in the parish and lords of the manor, were planning to sell some for development. With this in mind, a vote was cast which went in favour of becoming an urban district. The new district was designed to better reflect to increase in development, as councillors felt a parish council would work slower than an urban district.
