In 2020, I secured Class Q Prior Approval from Colchester City Council for the change of use of a redundant piggery building at Boxted, Colchester to a single one-bedroom residential dwelling.
The key planning challenges were demonstrating structural soundness, confirming the absence of significant external alterations, and managing potential contamination from the site's former agricultural use — all resolved through proactive engagement with the Council's Contaminated Land Officer.
Prior Approval Class Q in Colchester
I gained Class Q prior approval from Colchester City Council for the change of use of an agricultural building — a former piggery — to a single one-bedroom residential dwelling at Boxted, Colchester.
The wider site comprised a main farmhouse that had been renovated and a series of small agricultural outbuildings that had been redundant for several years.
An assessment of all the buildings was undertaken to identify which were most suitable for residential conversion under Class Q, and the piggery building was identified as the strongest candidate.
Class Q of the Town and Country Planning (General Permitted Development) (England) Order 2015 allows agricultural buildings to change to residential use without a full planning application, subject to a prior approval assessment covering specified matters only.
The former use of the site as a pig farm raised the question of ground contamination — a matter that is within the scope of the Class Q prior approval assessment and one that, if handled poorly, can result in conditions that are difficult and costly to discharge.
Rather than leaving this to emerge during determination, discussions were held directly with the Council's Contaminated Land Officer at an early stage. It was established and agreed that any contamination matters could be appropriately addressed through a planning condition, giving the Council the assurance it required without blocking the application.
Colchester City Council granted prior approval, bringing a redundant agricultural building back into residential use.
