May I try once more (this will be the last time, I promise) to sort out Stephen Mullin's problem, as follows:
To help Stephen Mullin (Letters, AJ 18.10.01), perhaps I should explain that Parker Morris standards were modified by later circulars and ceased to apply in 1981, while the Housing Cost Yardstick continued to operate.
Neither higher densities not the adoption of system building - which both attracted increased allowances - relied on resorting to multi-storey construction.
Coincidentally, in the same issue of the AJ, another letter quoted Sir Leslie Martin's opinion that the need for high buildings is a fallacy because high densities can be achieved with quite low buildings.
