The proposal sought an amendment to an existing permission and would introduce 2 small roof dormers at 1.5m wide, set within each flank roof slope, with a small hipped roof above. The dormer to the north elevation would replace two roof lights and the dormer to the south would replace one.

Officers considered that the dormers would result in little over 0.5m² increase in internal floor area, which they believed negligible. The changes would not have an unacceptable impact on the openness of the Green Belt or the character and appearance of the Area of Outstanding Natural Beauty.
