88 East Avenue, Hillingdon, Hayes, UB3 2HR

Main issues, as the Inspector framed them

• the living conditions that would be available to occupiers of the proposed flat, with regard to internal accommodation standards and private amenity space
• the effect of the development, including the modifications to the ground floor, on the appearance and character of the appeal property frontage and the wider street scene of East Avenue
• the potential impacts of the creation of the proposed basement in the absence of a basement impact assessment
• the effects the addition of the first-floor extension would have on the living conditions at the neighbouring property with regard to outlook and natural lighting

What decided it

The proposal failed to meet adopted space standards for internal accommodation and private amenity space, and the proposed basement was unacceptably contrary to policy due to the absence of a required basement impact assessment.
