Provided that -
(a) where the proposed development is taking place within a building divided into separate units "neighbouring land" shall include -
(i) those parts of the building conterminous with or within 4 metres of the unit for which the development is proposed, and
(ii) all units directly above and below the unit for which the development is proposed and all units directly above and below those parts of the building conterminous with or within 4 metres of the boundary of that unit, and
(iii) land outwith the building which is conterminous with or within 4 metres of the boundary of the unit for which the development is proposed.
(b) where the "neighbouring land" consists of or includes a building divided into separate units, and the proposed development is taking place within a building which is not divided into separate units only those units of that building which are conterminous with or are within 4 metres of the boundary of the land for which the development is proposed and all parts of the building directly above and below those units shall constitute neighbouring land;
(c) where the "neighbouring land" consists of or includes a building divided into separate units, and the proposed development is taking place within a building which is also divided into separate units, only those units of the former building which are conterminous with or are within 4 metres of the boundary of the unit for which the development is proposed and all parts of the building directly above and below those units shall constitute neighbouring land;
