Going back was not the choice. What to go back with was. An implemented prior approval for five dwellings is a material consideration of substantial weight, so the second application was never arguing whether five homes belonged here. It only had to show that these five were better.
The full story
The building is a steel framed fertiliser barn of roughly forty metres by twenty, four bays across, with corrugated sheeting over a brick perimeter wall and a concrete floor. It is not picturesque and it was never going to be. What it had going for it was scale, a farmstead that was already turning residential around it, and a structural report confirming it suitable for change of use subject to localised repair.
Permitted development gave the estate five dwellings and very little else. Under Class Q the assessment runs to a closed list, and design quality is not on it. The consented scheme reflected that. Balconies were recessed into the first floor of the garden elevation, gable openings were cut with sloping heads, no dwelling had defined private amenity space, there was nowhere for bins or bicycles, and first floor bedroom windows looked toward the neighbouring cottages.
What forced the second application was not the design but the calendar. A prior approval has to be completed, not merely started, and delays to a public right of way diversion and to the issuing of the decision notice had materially reduced the time available to finish. This is how Class Q schemes usually come unstuck, and it is worth knowing before you rely on one: the consent is the easy part, and the deadline is real.
So the second application was designed to the parameters of the first. Same building, same footprint, same five dwellings, no material increase in massing. Across the whole scheme the net addition is 25.01 square metres. That framing matters more than any individual improvement, because it removes the question the council would otherwise have had to answer. Five homes in open countryside had already been found acceptable. The only live question was whether these five were better than those five.
They were. The balconies came off and became flush juliettes. The angled heads were regularised into a rhythm that follows the barn's own structural bays. Every dwelling gained private amenity space, four of them as separate gardens along the garden side and the fifth beside the parking court. Bedroom windows were turned away from the boundary and the southern elevation obscure glazed. Thirteen parking spaces, bin and cycle stores, an electric vehicle charge point per home and roof mounted solar were designed in rather than negotiated afterwards. A landscape framework and an ecological corridor were added along the northern edge.
The site itself carried no designations. Not Green Belt, no landscape designation, no heritage constraint on the building, and outside any flood risk area. The barn and its hardstanding are previously developed land, and the authority could not demonstrate a five year housing land supply, so the presumption in favour of sustainable development applied. The case was therefore about the building, which is the position we wanted to be in.
Biodiversity was the hardest part, and it is the part worth understanding if you own a barn. The building sits on concrete. The site's baseline is 1.44 habitat units, and assessed on its own footprint the development is a net loss of 15.52 per cent. No amount of planting inside the red line fixes that. What fixed it was the rest of the holding: habitat creation on adjoining land in the estate's ownership added 0.37 units, bringing the scheme to a combined net gain of 10.12 per cent, satisfying the trading rules, secured by a thirty year management and monitoring plan. If you own a barn and nothing around it, that route is not open to you. If you own the farm, it usually is.
Permission was granted in June 2026, at the first application, seventy nine days after it was received, subject to fourteen conditions. The last of them removes permitted development rights from the finished houses: no extensions, no roof alterations, no outbuildings, no fences, without a fresh permission. Having spent three years arguing about what this building should look like, neither we nor the council wanted it altered by right afterwards.
