HC Deb 16 April 1973 vol 855 c21W
Mr. Douglas-Mann

asked the Secretary of State for the Environment what his Department estimates to be the respective average proportions of the cost of new houses attributable to land costs, building costs and developers' profit; and what changes have taken place in these figures over the last five years.

Mr. Eyre

This information is not available. The developer's profit depends partly on when the land was bought and also on rates of pay and costs of materials in the locality. Because these items of cost vary so much from one developer to another, reliable estimates of average costs and profits for new houses cannot be made.
