If affordable housing is really the goal, then tighter proposals are required to ensure that developments actually deliver this. The opportunity for developers to, in practice, deliver far lower than the 40% threshold for affordable housing on new developments of over 10 houses is far too high. Securing a site for development based on one promise and then whinging about “lack of commercial viability” until the requirement is watered down is appalling, yet very frequent behaviour. At the point a developer tries to renege on meeting this threshold, which is clearly known from the outset, the land should simply be removed from them at the price they paid for it (minus administrative costs of the process, which may be substantial) and passed to someone who can stick to the rules.
