asked the Secretary of State for Education and Science what is the average cost, at 1979 survey prices, of building (a) a 300-place primary school, (b) a 1,000-place secondary school and (c) a 100-place nursery school.

The information is as follows:

(a) £268,000.

(b) £1,761,000.

(c) £117.000.

The figures are purely illustrative. They are based on the average unit cost of construction for projects started in 1978–79, excluding expenditure on land, fees and equipment and the abnormally high costs of certain sites.
