The Planning Inspectorate Hearings into Welborne took place in 2014. By 2022 building was yet to start, with the completion date for the first houses having become scheduled for 2023/24. On 6 June 2022 the Planning Inspectorate examined the 2037 Fareham Local Plan, and in the post-hearing letter noted that he considered completion of the first Welborne houses by 2023/24 to be "overly ambitious" and that the site "should be pushed back a year in the trajectory". Fareham Borough Council voted to impose
Compulsory Purchase Orders on landowners on the planned site in 2016. The council expressed concern in 2018 that the planned houses could be unaffordable A submitted design for the site was rejected by the
Planning Inspectorate in 2018, over concerns that the area's infrastructure would be inadequate. In August 2023 the developers announced that three regional builders had been selected to build out the first phase comprising 600 homes. These were Thakeham, CG Fry & Son and Pye Homes who have been selected under a “partnership” model, meaning they will not be required to pay up front for the land. Payment will only have to pay for the sites once the completed homes are sold on to new residents. By December 2023, the energy centre which was to house the electricity supply for the proposed 6,000 homes had gained consent. However, in the same month, a report revealed that
Hampshire County Council was "extremely unlikely" to be able to fund the revisions proposed to junction 10 of the
M27 without further funding. The council then confirmed that no further funding was anticipated from
National Highways or the
Department for Transport throwing the junction scheme into doubt. The spending of £113.5 million on the plans for Junction 10 were eventually given the go ahead by Hampshire County Council in January 2025. ==Local responses==
