Housing was a major policy area under Wilson's Labour government, 1964 to 1970, with an accelerated pace of new building, as there was still a great deal of unfit housing needing replacement. Tower blocks, first built in the 1950s, featured prominently in this era. The proportion of council housing rose from 42% to 50% of the nation's housing total, while the number of council homes built increased steadily, from 119,000 in 1964 to 133,000 in 1965 and to 142,000 in 1966.
