Sch 10 para 18 Scope of the option
(1) An option to tax has effect in relation to the particular land specified in the option. (2) If an option to tax is exercised in relation to— (a) a building, or (b) part of a building, the option has effect in relation to the whole of the building and all the land within its curtilage. (3) If an option to tax— (a) is exercised in relation to any land, but (b) is not exercised by reference to a building or part of a building, the option is nonetheless taken to have effect in relation to any building which is (or is to be) constructed on the land (as well as in relation to land on which no building is constructed). (4) For the purposes of this paragraph— (a) buildings linked internally or by a covered walkway, and (b) complexes consisting of a number of units grouped around a fully enclosed concourse, are treated as a single building. (5) But for those purposes— (a) buildings which are linked internally are not treated as a single building if the internal link is created after the buildings are completed, and (b) buildings which are linked by a covered walkway are not treated as a single building if the walkway starts to be constructed after the buildings are completed. (6) In this paragraph a “building” includes— (a) an enlarged or extended building, (b) an annexe to a building, and (c) a planned building. (7) In this paragraph “covered walkway” does not include a covered walkway to which the general public has reasonable access.
