Prior notification is required and refused.
  2. The proposed works are NOT permitted development by virtue of Schedule 2, Part 1, Class A of the Town and Country Planning (General Permitted Development) (England) Order 2015 as amended by virtue of the proposed development would have a detrimental impact on the amenities of the occupiers of adjoining neighbour in terms having an overbearing and dominant effect to this property and would result in harm to the living conditions through a loss of light and outlook.
