An Inspector has dismissed an appeal against non-determination of an application for a logistics/warehousing development comprising 120,000sqm B8 floorspace adjacent to junction 17 of the A12 in Essex, following an inquiry conducted in the autumn of last year.

Planning balance and need for logistics floorspace

Chelmsford City Council had assessed its need for new logistics floorspace as part of preparations for its new local plan, and made a draft allocation in the emerging plan for a logistics development comprising 46,605sqm adjacent to junction 18 of the A12, about a mile further up the road, to help to meet those identified needs (and as part of a planned expansion of Chelmsford to the east). The promoter of the junction 17 site appealed for non-determination, and so did the promoter of the junction 18 site; both inquiries were scheduled in late 2025, but not conjoined. In the event, the proposal at junction 18 was supported by the authority at the inquiry, and permission was granted by the inspector in December 2025.

This Case in 60 seconds

  • Cornerstone’s Josef Cannon KC successfully represented Chelmsford City Council in resisting an appeal against the non-determination of an application for a 120,000 sqm B8 logistics development adjacent to junction 17 of the A12, Essex.
  • This appeal followed a public inquiry held in Autumn 2025.
  • The Council had separately assessed its logistic floorspace requirements and made an alternative draft allocation for a logistics development comprising 46,605sqm adjacent to junction 18 of the A12.
  • The proposal on the draft allocation was supported by the Council at the inquiry, and permission was granted by the inspector in December 2025.
  • The Inspector found the Junction 17 scheme to be contrary to the adopted development plan and that it would cause significant harm to the surrounding landscape.
  • Additional concerns included harm to heritage assets, highway safety and capacity concerns, and the loss of protected trees.
  • The Inspector also rejected the appellant’s assertion that there was an acute and urgent need for the development.
  • Set against the undoubted benefits of the proposals, these harms significantly and demonstrably outweighed the benefits.
  • The decision reflects the careful and balanced approach adopted by Chelmsford City Council and its team throughout the process.

On the junction 17 proposal, Chelmsford had to wait a while longer but on 2 July 2026 the appeal was dismissed. The Inspector found the proposals to be contrary to the adopted development plan (which was common ground) and that it would cause significant landscape harm, including from the loss of protected trees; less than substantial harm to nearby heritage assets via their setting, as well as a moderate level of harm to three non-designated WW2 pillboxes on the site. In terms of highway safety, the proposals included effectively reversing a recent safety-led improvement to junction 17 itself, which National Highways objected to on safety grounds: on this and other safety and capacity concerns the Inspector found himself unable to conclude that there would be no unacceptable effect on the operation, capacity or safety of the network, harm that weighed very substantially against permission.

Key harms identified by the Inspector

Set against the undoubted benefits of the proposals, these harms significantly and demonstrably outweighed the benefits. Of particular note was his finding that, although (as agreed between the parties) the proposals would meet a need for regional-scale logistics, the Appellant’s claim that this need was acute and urgent was not supported, and (issues of need having taken up the majority of the inquiry) attracted no more than significant weight.
