The reasons for refusal here are the dormer windows over-looking the neighbours at the rear, and that the proposal is cramped and contrived.
This is a definite building plot, in an established cul-de-sac, and albeit there is a refusal, there will be a scheme that is acceptable.
PAPA Says - The front elevation could not be more simple, the dormers need to be removed and a simple scheme for a 2-bed cottage should gain approval. if not, go to appeal on the second decision.
