"The primary purpose of section 2(2) must have been to exclude from the operation of the Act houses in respect of which the inability of one freehold owner to enforce positive obligations against successors in title of the other would be likely to prejudice the enjoyment of the house or another part of the structure."
"if the part of the house which lies above or below a part of the structure not comprised in it is of sufficient substance or significance to make it likely that enfranchisement will prejudice the enjoyment of the house or another part of the structure, whether by reason of the inability of one freehold owner to enforce positive obligations against successors in title of the other or otherwise, then it is a material part of the house within section 2(2)."
"Assuming that 'material' does not simply point the contrast with 'trivial' or 'insignificant,' I think that it must mean material to the tenant or to his enjoyment of the house, and that if it is material in that sense it will be of such significance as to alter the house into a flat, and so take it outside the Act."
"Then it was necessary to make provision for mixed cases, where units were separated by a broken vertical line, or as it might be expressed, partly vertically and partly horizontally. This I take to be the purpose of subsection (2) and it uses as the discrimen the lying of a material part above or below a part of the structure to which the house is attached. It was necessary to confine the exemption to cases of structural attachment, in order not to include within it cases of mere projection, over or under another structure, without attachment."
"In ordinary legal parlance 'material', used adjectivally, is not found in a vacuum. It imports a reference to something else. The thing to which it is applied must be material to some inquiry or for some purpose. It must be of sufficient substance or significance to have an effect of some kind."
"That part of 76 Harley Street which undercuts 27 Weymouth Mews provides support to the rear flank wall of 27 Weymouth Mews and, if the basement walls were to fall into disrepair so as to remove that support, the rear flank wall of 27 Weymouth Mews at ground floor and first floor level would fall down."
"Whatever meaning be given to 'material' in this context, whether I consider its size or its rateable value or its history or the use to which it is now put, I find it impossible to say that this part of the tenant's house was not material. ......... It has value and importance to the tenant ........ It must be worth taking over. ............ Assuming that 'material' does not simply point the contrast with 'trivial' or 'insignificant', I think that it must mean material to the tenant or to his enjoyment of the house, and that if it is material in that sense it will be of such significance as to alter the house into a flat, and so take it outside the Act. "
"I would therefore hold that if the part of the house which lies above or below a part of the structure not comprised in it is of sufficient substance or significance to make it likely that enfranchisement will prejudice the enjoyment of the house or another part of the structure…..then it is a material part of the house within section 2(2). In practice it may be found that that test will exclude from the operation of the Act houses of which little more than a trivial or insignificant part lies above or below a part of the structure not comprised in it…."

"2(1) For purposes of this Part of this Act, 'house' includes any building designed or adapted for living in and reasonably so called, notwithstanding that the building is not structurally detached, or was or is not solely designed or adapted for living in, or is divided horizontally into flats or maisonettes; and— "(a) where a building is divided horizontally, the flats or other units into which it is so divided are not separate 'houses', though the building as a whole may be; and (b) where a building is divided vertically the building as a whole is not a 'house' though any of the units into which it is divided may be. (2) References in this Part of this Act to a house do not apply to a house which is not structurally detached and of which a material part lies above or below a part of the structure not comprised in the house. (3) Subject to the following provisions of this section, where in relation to a house let to and occupied by a tenant reference is made in this Part of this Act to the house and premises, the reference to premises is to be taken as referring to any garage, outhouse, garden, yard and appurtenances which at the relevant time are let to him with the house and are occupied with and used for the purposes of the house or any part of it by him or by another occupant."
"(5) In relation to the exercise by a tenant of any right conferred by this Part of this Act there shall be treated as not included in the house and premises any part of them which lies above or below other premises (not consisting only of underlying mines or minerals), if — (a) the landlord at the relevant time has an interest in the other premises and, not later than two months after the relevant time, gives to the tenant written notice objecting to the further severance from them of that part of the house and premises; and (b) either the tenant agrees to the exclusion of that part of the house and premises or the court is satisfied that any hardship or inconvenience likely to result to the tenant from the exclusion, when account is taken of anything that can be done to mitigate its effects and of any undertaking of the landlord to take steps to mitigate them, is outweighed by the difficulties involved in the further severance from the other premises and any hardship or inconvenience likely to result from that severance to persons interested in those premises."
"First, the question whether the particular premises were a 'house' within the definition was a mixed question of fact and law . . . Secondly, if the premises might also be called something other than a 'house' within the definition, that fact alone did not prevent those premises from being a 'house . . . reasonably so called.' Thirdly, it was implicit from such previous decisions as there have been upon this question that premises used for non-residential as well as for residential purposes could in law be a 'house' within the definition and that it depended upon the character of the premises in question whether by reason of their mixed user they fell within or without the definition."
"Assuming that 'material' does not simply point the contrast with 'trivial' or 'insignificant', I think that it must mean material to the tenant or to his enjoyment of the house, and that if it is material in that sense it will be of such significance as to alter the house into a flat, and so take it outside the Act. Whether it was material in that sense is a question of fact and degree . . ."
"'Important' is sometimes synonymous with 'material', but at other times it is not. The problems inherent in treating them as equivalents are demonstrated by the judgment of Judge Rich QC. He thought the basement area important because it would add considerably to the price of the house in the market. But he held nevertheless that it was not a material part of the house. So Lord Denning MR's test has not been helpful in this case."
"…. a separate set of premises (whether or not on the same floor)— (a) which forms part of a building, and (b) which is constructed or adapted for use for the purposes of a dwelling, and (c) either the whole or a material part of which lies above or below some other part of the building."
"From 1775 the entirety of the site between Harley Street and Weymouth Mews was occupied by a built structure …. and until some date in the 1930s (at the earliest) it would have been reasonable and natural to call the whole of that structure a house."
"…. the reference to premises is to be taken as referring to any garage, outhouse, garden, yard and appurtenances which at the relevant time are let …. with the house and are occupied with and used for the purposes of the house …."
