Land off Pyotts Hill, Old Basing, Basingstoke, Hampshire, RG24 7NX

Main issues, as the Inspector framed them

• the effect of the development on the character and appearance of the area, including whether the development would preserve or enhance the character or appearance of the Old Basing Conservation Area
• the effect of the development on trees
• the effect of the development on biodiversity
• risk from contamination
• the effect of the development on flood risk

What decided it

The cumulative harms to the conservation area, trees, biodiversity, contamination risk and flood risk, particularly the less than substantial but still significant harm to the heritage asset to which great weight must be attributed, significantly and demonstrably outweighed the modest benefit of one additional dwelling.

The adverse impacts of the development, including less than substantial harm to the conservation area heritage asset (to which great weight must be attributed), significantly and demonstrably outweighed the scheme's benefits of providing a single dwelling, such that the presumption in favour of sustainable development did not apply.
