the problem here is the fact that a lot of these permissions were only granted on the 106 agreements, being agreed to, when the cost of building them was viable (often some time ago) ....
now everything's gone up so much, the 'affordables' are costing more to build than the ceiling prices for the social landlord owners to stomach and they just aren't prepared to buy, even at cost .....
developers're gonna have to take a hit - end of - and take a smaller slice of the profit on those that aren't 'so called'
affordable which they couldn't have built, without agreeing to the 106 agreements in the first place
