Main issues, as the Inspector framed them

  • The effect of the development upon the character and appearance of the area

What decided it

The low percentage of HMO conversions on the street (4.6%), absence of evidence of harm to residential character or neighbours' living conditions, and the development's contribution to housing mix diversity outweighed the technical breach of the 1 in 5 consecutive row policy restriction.
