In return for extending the duration of permissions affected, developers will be required to make a once-off contribution towards funding social and affordable housing. The alternative was to do nothing and leave these sites to wither. There would have been no gain, financial or otherwise. I chose to try to keep the sites viable and to go further than was provided for in the previous Act by seeking a levy from the developers which will go directly to the local authorities. They will thus have more funding available to them for social and affordable housing. I hope Members who comment on this point will be prepared to propose another alternative. The one facing us was to leave the sites to wither, in which case nobody would gain anything. A total of 80,000 permissions would have been lost from the market on the supply side. I have restored them but have gone further by securing a substantial community gain for the housing stock. That is a more imaginative approach.
