54Matters which may be taken into account by Minister in listing buildings.
In considering whether to include a building in a list compiled or approved under section 32 of the principal Act, the Minister 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 consisting of a man-made object or structure fixed to the building or forming part of the land and comprised within the curtilage of the building.
