Main issues, as the Inspector framed them
- whether the proposed pergola, extension to the triple garage and outbuilding would be inappropriate development in the Green Belt having regard to the National Planning Policy Framework and any relevant development plan policies
- the effect of the pergola, extension to the triple garage and an outbuilding on the openness of the Green Belt
- the effect of the pergola on the character and appearance of the area
- if the proposal would be inappropriate development, whether the harm by reason of inappropriateness, and any other harm, is clearly outweighed by other considerations, so as to amount to very special circumstances to justify it
What decided it
The proposed development would constitute inappropriate development in the Green Belt by reason of disproportionate additions to the original dwelling, and the resulting moderate harm to openness is not clearly outweighed by other considerations, so very special circumstances do not exist.
