This is a really interesting scheme. The majority of the properties built will be houses sold as freehold properties. There are a relatively small number of rented and shared ownership properties.
This is the new way of funding social or affordable housing so its pointless to blame the HA for it.
Secondly this is a really interesting scheme because there is s genuine attempt being made to create fairly large swathes of housing that are carbon neutral and are sustainable with much lower use of scarce resources.
