Paragraph 84 (formerly Paragraph 80) of the National Planning Policy Framework and Class Q barn conversions are two of the most powerful, exciting - and lesser-known opportunities in residential planning. For landowners, architects and anyone dreaming of a countryside or seaside home in Cornwall or nationwide, these policies can unlock projects that would normally be refused under standard planning rules.
From contemporary “Grand Designs”‑style homes to sensitive barn conversions, these routes offer a genuine chance to create exceptional rural homes in the UK’s most beautiful landscapes. But success depends on specialist knowledge, a clear strategy and an understanding of how local authorities interpret the rules.
I provide expert planning advice for Paragraph 84 projects and Class Q barn conversions across Cornwall and the South West.

Why Paragraph 84 and Class Q Matter in Cornwall
Cornwall’s rural planning policies are some of the most complex in the country. AONBs, National Landscapes, heritage settings and strict countryside protection policies mean most new homes in the open countryside are refused.
Paragraph 84 and Class Q are the exceptions — but only when used correctly.
What “truly outstanding” means under Paragraph 84
Paragraph 84 homes must be landscape‑led, architecturally exceptional, demonstrate contextual sensitivity and demonstrate significant enhancement to their setting. This is achievable, but only with a clear planning strategy and the right design team.
Why Class Q is powerful
Class Q allows the conversion of agricultural buildings into homes without a full planning application — but only if the building meets strict criteria. Many applications fail because the fundamentals weren’t assessed early enough.
Cornwall‑specific interpretation
Understanding local precedent, local landscape character and political context is essential.
Unlocking personal ambition
For many clients, these policies unlock something bigger than a planning consent: the chance to build a life in the countryside, create a legacy home, or realise a long‑held dream.
