Main issues, as the Inspector framed them
- whether the proposal would comply with the relevant policies relating to development in the green belt
- the effects on the character and appearance of the area
- the effects on living conditions at the adjoining property, Cherry Tree Cottage
What decided it
The replacement building was materially larger than the original shed and the original was not of permanent and substantial construction, placing it outside the green belt replacement building exception, combined with substantial harm to openness and poor design quality.
The harm to the green belt by reason of inappropriateness and loss of openness, and harm to character and appearance, were not outweighed by any other considerations of significant weight, as no very special circumstances existed.
