A range of new permitted development rights were introduced by the coalition government in 2015 in order to simplify conversion of existing agricultural buildings to new uses. The Class Q subsection of these rights enables farm buildings to be converted into residential dwellings. Where existing planning policies rigorously focused on preservation of traditional heritage farm buildings through conversion, the new permitted development rights enabled conversion of much more modern commercially constructed buildings such as steel portal framed buildings.
These new types of building offered a much more flexible building envelope for conversion and consequently broader design opportunities. However, the new permitted development rights, when appropriate conditions are satisfied, do not provide scrutiny of the design of these conversions. There is therefore an amount of design freedom not normally permitted in the full planning process, and an opportunity for a new vernacular formed outside of the normal engagement of architectural design and formal planning permission design evaluation.
This research is at an emerging stage. Through reference to case studies in a tight geographical area in Dorset, the study looks at the changes in vernacular character which are happening through these types of approval, and the mechanisms through which design decisions are being made by the people implementing them, who are not necessarily architects.
There are few studies that investigate the impact that Class Q Permitted Development Rights have had. Many building projects have been realised as a result of this policy, but there has been limited research into its impact on the design of rural housing, or on the practice of architecture in rural settings. The project could inform the iteration of the relevant planning policy and the development of rural architectural practice.
