Aylesbury Vale District Council has cut the number of new homes it requires as it prepares the final version of the Vale of Aylesbury Local Plan (VALP).
The figures have been revised by the district council following recent reductions in the population growth forecasts.
The neighbouring authorities Wycombe, Chiltern and South Bucks have found more space for housing, and all this means the latest figure for new homes in the Vale is now below 27,000 - more than 6,000 fewer than the 33,300 figure in the draft local plan.
Such a large reduction in housing needs means planners are revising the proposals put forward in the draft local plan.
Additional work is needed to make detailed assessments of proposed sites and to devise a new strategy, taking into account the consultation feedback.
District council planners say that the revised new figures mean that over half of the new homes required to meet housing needs in the district by 2033, are already built or have planning permission.
The district council has also revised the timetable for bringing the final plan to council meetings, which is now March 2017 meaning final consultation is likely to start in April.
Cllr Carole Paternoster, cabinet member for strategic growth said: “We are very pleased to hear the population forecasts have been lowered and that other areas have found more capacity, but we will continue to robustly challenge unmet needs from other authorities as we move forward.
“We regret that it will take longer to prepare the plan but we have to ensure that we deliver a workable and well considered local plan that makes Aylesbury Vale a special place to live and work.”
