asked the Minister of Health if he will explain his reasons for permitting an increase on working-class houses of £100 per house; what were the items of increased costs that he considered; and if he will state the respective values assessed on each, in order to arrive at the total cost of £100 above referred to.

The reasons for authorising an increase in the maximum selling prices of houses to be built under licence are set out in the Circular to local authorities of which I am sending my hon. Friend a copy.
