Main issues, as the Inspector framed them
- Whether the Council's decision to refuse to issue a Lawful Development Certificate was well-founded
What decided it
The appellants failed to provide sufficient evidence (specifically the historical map they referenced) to demonstrate on the balance of probabilities that the existing kitchen and bathroom formed part of the original dwelling, and therefore could not prove the combined extensions would comply with the 3-metre depth requirement under Class A of the permitted development order.
