Mr Frost said he did not think there was “an issue in principle of coming back and maximising the benefit of providing affordable housing where it is required”.
Planning officers agreed there had been an under-delivery of affordable housing over the years, adding there was a “significant need” for affordable housing across East Cambridgeshire.
However, they said the need for affordable homes in the Stretham and Little Thetford area ranged from 44 to 72 homes, which they said would be “appropriately met” by the previously approved plans for 83 homes on the site.
Officers recommended that the application for 126 homes should therefore be refused, which was endorsed by a majority of councillors in a vote.
The developer still has permission to build up to 83 affordable homes on the site, and said more detailed plans will be submitted later this year.
They can also appeal the district council’s decision to refuse permission for the 126 homes.
