80.—(1) The Department—
(a)shall compile lists of buildings of special architectural or historic interest; and
(b)may amend any list so compiled.
(2) In considering whether to include a building in a list compiled under this section the Department may take into account not only the building itself but also—
(a)any respect in which its exterior contributes to the architectural or historic interest of any group of buildings of which it forms part; and
(b)the desirability of preserving, on the ground of its architectural or historic interest, any feature of the building which consists of a man-made object or structure fixed to the building or which forms a part of the land and which is comprised within the curtilage of the building.
(3) Before compiling or amending any list under this section, the Department must consult with the appropriate council and the Historic Buildings Council.
(4) As soon as may be after any list has been compiled under this section, or any amendments of such a list have been made, the Department must cause a copy of so much of the list, or so much of the amendments, as relates to the district of a council to be deposited with the clerk of that council.
(5) As soon as may be after the inclusion of any building in a list under this section, whether on the compilation of the list or by its amendment, or as soon as may be after any such list has been amended by the exclusion of any building from it, the Department must serve a notice in the prescribed form on every owner and occupier of the building, stating that the building has been included in, or excluded from, the list, as the case may be.
(6) The Department must keep available for inspection by the public at all reasonable hours copies of lists and amendments of lists compiled or made under this section.
(7) In this Act “listed building” means a building which is for the time being included in a list compiled under this section; and, for the purposes of the provisions of this Act relating to listed buildings, the following shall be treated as part of the building—
(a)any object or structure within the curtilage of the building and fixed to the building;
(b)any object or structure within the curtilage of the building which, although not fixed to the building, forms part of the land and has done so since before 1st October 1973.
