Main issues, as the Inspector framed them
- whether the proposal would provide an appropriate mix of housing
- whether the proposal would provide adequate living conditions for future occupiers with particular regard to light, outlook and standard of accommodation
- the effect of the proposal upon the character and appearance of the area
What decided it
The cumulative harm to housing mix, living conditions for future occupiers, and character and appearance, when weighed against the modest benefits of a single additional housing unit, significantly and demonstrably outweighed the benefits when assessed against the Framework and development plan policies taken as a whole.
The modest benefits of one additional housing unit, use of previously developed land, good access to sustainable travel, quick delivery potential, and temporary economic boost were significantly and demonstrably outweighed by harm to housing mix, failure to provide adequate living conditions, and harm to character and appearance.
