HC Deb 30 March 1983 vol 40 c169W
Mr. Frank Allaun

asked the Secretary of State for the Environment if he will estimate the approximate number of jobs in the British building materials industry which have been lost through the use of timber frames, steel frames, in situ concrete, reinforced concrete and other categories, respectively, of non-traditional materials.

Sir George Young

No; it is not possible to estimate reliably what the level of employment in the building materials industry would have been had such widely used materials not been introduced.
