The agricultural shed fell within the Green Belt exception
The current National Planning Policy Framework lists development that is for agriculture, horticulture and forestry among development that is not inappropriate in the Green Belt. Northumberland’s concern included the lack of an established agricultural enterprise or business. The Inspector did not consider that an additional test contained in national Green Belt policy. The decision states that Policy GB7 refers to development for agriculture and does not require it to serve an established agricultural business or enterprise. That distinction is important. A smallholder, landowner or developing agricultural operation is not automatically excluded from the Green Belt exception simply because it is not a large or long-established commercial farm.
But there still had to be genuine agriculture
The appeal succeeded because the Inspector was satisfied about what the building was actually for. The shed stored equipment and materials connected with the land, including livestock feed and fencing equipment. Evidence of livestock activity had been provided and sheep were present when the Inspector visited. Our guide to whether land is agricultural or equestrian explains why the character of the activity matters more than the label a landowner gives it. The same point matters when considering agricultural permitted development rights. Those rights have their own detailed tests, but they also depend on there being a genuine agricultural use rather than simply rural land with machinery stored on it.
The Stafford tractor appeal shows the other side
The contrast with a recent appeal at The Ferns, Brocton, Stafford, appeal 6010165, is particularly useful. In that case tractors and equipment were mainly associated with maintaining privately owned land. The appellant did not put forward an established commercial agricultural enterprise, but that was not the decisive problem. The Inspector found insufficient evidence that the activity itself amounted to agriculture, horticulture, forestry or the other uses falling within the relevant Green Belt exception. The building therefore could not rely on the agricultural route simply because tractors and rural land were involved. At Breckon Hill the evidence was different: livestock activity was real and the shed served that agricultural use. Planning Geek analysis: read together, the two decisions draw a useful line. You do not need to prove a large established commercial farm merely to satisfy the agriculture limb of Green Belt policy, but you do need to prove genuine agriculture. Machinery is evidence only of what it is actually being used for.
Green Belt openness did not create a second hurdle
Once the Inspector found that the shed fell within the agricultural category of Policy GB7, it was not inappropriate development in the Green Belt. The Inspector did not then treat the building’s effect on openness as though it had to pass the very special circumstances test used for inappropriate development. The proposal was also found not to cause unacceptable landscape harm. The fact that another location might theoretically have been chosen did not justify refusal where the building in its actual position was not causing material harm. Our guide to Green Belt and grey belt explains the different national policy routes.
The permission was tied to agricultural use
The Inspector imposed a condition restricting the building to agricultural purposes within the meaning of section 336(1) of the Town and Country Planning Act 1990 and to no other purpose. The condition also addressed changes of use that might otherwise be claimed through permitted development rights. In practical terms, the permission was granted because the building was accepted as agricultural, and the condition was intended to keep it within that assessed use. Section 336 contains the statutory planning definition of agriculture, which includes activities such as the breeding and keeping of livestock and the use of land as grazing land. This is not a condition that proves the present use by itself. The Inspector had already reached the factual conclusion that the building genuinely served agriculture before imposing it.
Retrospective permission did not change the policy test
The shed already existed, so the application and appeal were retrospective. That did not create a different Green Belt test. The benefit of a retrospective case is that the Inspector can often see the building and its actual use rather than having to rely entirely on predictions. Here, the stored equipment and livestock activity helped show what the building was serving. Our guide to retrospective planning applications explains how the process works where development has already taken place.
The Planning Geek takeaway
This is not a loophole for sheds on Green Belt land. The useful point is narrower: current national Green Belt policy asks whether the development is for agriculture. It does not add a separate requirement for an established commercial farming enterprise. But the agricultural use still has to be real. Breckon Hill had livestock activity and a shed serving that activity. The Ferns had tractors and land management, but insufficient evidence of agriculture. Anyone relying on an agricultural planning route should therefore prove the activity first and describe the building second.
