There is one – large – detail. Two-thirds of the original 1,000 council flats will, with the help of public subsidy to the development, now be for private sale. The council says that it’s better to have a mixture of tenures than to remake a “ghetto” of council tenants. This follows the current orthodoxy and might be entirely reasonable if the homes were being replaced elsewhere in the city. Instead, there has been a demolition derby of council flats, leaving cleared sites which “haven’t been built on as fast as we would like”. This problem is not the size of Park Hill, it’s the size of Sheffield.
