As a result of the railway, more commuters gradually moved to Ickenham and travelled to work in London. On 5 July 1922, of the Swakeleys estate was auctioned for development, thereby significantly reducing its size. Roads laid out for the new development were Warren Road, Swakeleys Drive, Court Road, Milton Road, Ivy House Road, The Avenue and Thornhill Road (originally named Park Road). Other land bordering the River Pinn was designated as public open land. Shops were built around Swakeleys Road, while houses were constructed along its length. The road was widened to become a dual carriageway in 1937. Milton Farm, one of the farms on the former Swakeleys estate was demolished in 1939. The farm's pond and listed barn were cleared to make way for housing in what became Milton Road and Milton Court, though marketed as "Ickenham Garden City".
