Hackworthy Farm was a great example of how Class Q can unlock the potential of disused barns - we designed two plots with full planning approval for our client to sell. The first step was securing permitted development rights under Class Q. From there, we submitted a full planning application, justifying two bespoke dwellings as a “betterment” to the original Class Q approval.
