Acquisition of subsoil or air-space only
26.—(1) The undertaker may compulsorily acquire so much of, or such rights in, the subsoil of, or the air-space over, the land referred to in article 19 (compulsory acquisition of land) and article 22 (compulsory acquisition of rights) as may be required for any purpose for which that land may be acquired or for which rights over or under the land may be acquired under those provisions instead of acquiring the whole of the land.
(2) Where the undertaker acquires any part of, or rights in, the subsoil of or the air-space over land under paragraph (1), the undertaker is not required to acquire an interest in any other part of the land.
(3) Paragraph (2) does not prevent article 27 (acquisition of part of certain properties) from applying where the undertaker acquires a cellar, vault, arch or other construction forming part of a house, building or manufactory.
