Main issues, as the Inspector framed them
- The effect of the proposed development on the character and appearance of the area including the Tamar Valley National Landscape
- Whether the appeal site is in an appropriate location for housing, having regard to the development plan
- The effect of the proposed development on the integrity of the Plymouth Sound and Estuaries Special Area of Conservation and the Tamar Estuaries Complex Special Protection Area
- Whether there are any material considerations, including the Framework which would outweigh any identified harm
What decided it
The significant shortfall in housing land supply (3.8 years) triggered the tilted balance under paragraph 11(d) of the Framework, and the benefits of housing delivery and sustainable location outweighed the conflict with the development plan's spatial strategy.
The conflict with the development plan's spatial strategy was given significant weight, but this was outweighed by the significant weight given to housing supply benefits, sustainable location benefits (access to services without car reliance), and the great weight given to the finding of no harm to the Tamar Valley National Landscape, resulting in permission being granted under the tilted balance.
