In 2016, Epping Forest District Council approved planning permission for the conversion of a barn to a residential dwelling, together with a substantial extension, on Green Belt land in Essex.
An earlier permission had converted the barn to an annexe, but the Council had resisted any further expansion. The case was resolved by successfully identifying Green Belt exceptions criteria and relevant case law justifying the extension.
Green Belt Issues in Epping Forest
Epping Forest District Council had previously granted planning permission for the conversion of an existing barn to a residential annexe, but had made clear it would not support further expansion of the building given the restrictive Green Belt policies that apply throughout its area.
The challenge was to negotiate a substantially larger extension — approximately 30% greater than what had previously been permitted.
Green Belt policy under the NPPF establishes a strong presumption against new buildings and inappropriate development.
However, certain exceptions exist, and the success of this application depended on demonstrating that the proposed extension fell within those exceptions and did not constitute inappropriate development in the Green Belt.
Two site-specific arguments proved particularly important.
First, a derelict barn stood adjacent to the site, and it was demonstrated that the proposed extension would effectively replace that structure — a material consideration that carried meaningful weight in the planning balance.
Second, a detailed analysis of the site's history established that the two barns had historically been attached, supporting the argument that the extension was part of a continuous built form rather than a new intrusion into the Green Belt.
Relevant case law was also cited to support the argument that the scale of the extension increase would not constitute inappropriate development.
Following thorough engagement and negotiation with the case officer, Epping Forest District Council was persuaded and planning permission was granted.
