"1. The case concerns a mews house and premises known as 3 Grosvenor Gardens Mews East, London SW1 ("the house")." 2. The house lies at the back of number 3 Grosvenor Gardens. Adjoining the house to the North [the right as one looks at the house from Grosvenor Gardens Mews East] lies 1/1A Grosvenor Gardens (referred to as 1/1A Grosvenor Gardens). Another mews house adjoins the house to the left [South], The house is not structurally detached. 3. The house comprises two storeys. 1/1A Grosvenor Gardens is several storeys higherand considerably taller. 4. The house and 1/1A Grosvenor Gardens are divided by a single wall. The externalflank wall of the Southern elevation of 1/1A Grosvenor Gardens at second floor level and above is a vertical continuation of the same wall which separates the house from 1/1A Grosvenor Gardens at ground and first floor level."
"one half severed vertically of party walls dividing such building from adjoining premises."
"(1) This Part of this Act shall have effect to confer on a tenant of a leasehold house ... a right to acquire on fair terms the freehold ... of the house and premises."
"(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 sodivided 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 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."
"(4) In relation to the exercise by a tenant of any right conferred by this Part of this Act there shall be treated as included in the house and premises any other premises let with the house and premises but not at the relevant time [subject to a tenancy vested in him] (whether in consequence of an assignment of the term therein or otherwise) if- (a) the landlord at the relevant time has an interest in the other premises and, not laterthan two months after the relevant time, gives to the tenant written notice objecting to the further severance of them from the house and premises; and (b) either the tenant agrees to their inclusion with the house and premises or the court issatisfied that it would be unreasonable to require the landlord to retain them without the house and premises. (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 laterthan 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 thecourt 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."
"... that as a matter of common sense there is in fact no deviation from the vertical plane of division between the house and 1/1A (i.e. there is no overhang/underhang); the division between two is a single wall and the considerations of section 2(2) are not engaged and do not arise." "… that if it is a deviation from the vertical plane of division, then it is de minimis and, again, section 2(2) is not engaged."
"in reaching conclusions on these competing submissions, it seems to me that Mr Radevsky's submissions are, when looked at from a purist and technical perspective, attractive, but turning to the claimant's first submission and the guidance given by Lord Nicholls in paragraph 3 of Malekshad, it seems to me that one has to take a common sense approach to resolution of issues such as this. There has to be a point at which the court says that the distinctions being drawn by a landlord in such situations are too fine. There is little guidance as to what physical structure is contemplated by the reference to a vertical division for the purposes of section 2(1)(b) and for the purposes and in the context of section 2(2), but it seems to me that some help can be derived from the speech of Lord Hope in Malekshad, where the sort of kink or deviation which he had in mind as causing concern would be a room or a cupboard. In other words something visually apparent and relatively substantial." "
"Although the 1967 Act like the 1993 Act is in a sense expropriatory, in that it confers rights on lessees to acquire rights compulsorily from their lessors, this has been held not to give rise to any interpretative presumption in favour of the latter. As Millett LJ said of the 1993 Act: "
"From section 2(1) it appears, and indeed it is well known, that the Act was intended to provide "enfranchisement" for dwelling houses but not for flats. Flats, as are "strata" in other systems, are units which arise by horizontal division of a building, and by this criterion they are excluded by paragraph (a). On the other hand, the Act evidently intended to allow enfranchisement of terrace houses and dwellings arising by vertical division. This is effected by paragraph (b). If one seeks a reason for this different treatment, it may lie in the difficulty, in relation to units arising by horizontal division, of providing, after they become freehold by enfranchisement, for the enforcement of necessary positive covenants — a difficulty which did not exist while they were leasehold. Possibly there were other reasons for the discrimination: at any rate it was clearly made in section 2(1) of the Act." "
"2 This appeal raises the question of the proper interpretation of the phrase "material part" insection 2(2) of the Leasehold Reform Act 1967 . The context is that the Act confers a right of enfranchisement on the tenants of some, but not all, residential units. Houses may be enfranchised, flats may not. So the statute has to draw a demarcation line between houses and flats. Typically a flat comprises one floor, or part of one floor, of a building. So section 2(1)(a) excludes from the concept of a "house" the flats or other units resulting from the horizontal (side to side) division of a building. Typically also a house may be structurally attached to other property, as with a semidetached house or a terraced house. So section 2(1)(b) provides that where a building is divided vertically (from top to bottom), the building as a whole is not a house though any of the units into which it is divided may be." "3 So far so good. But divisions of a building, either as originally constructed or later adapted, are frequently not wholly along straight lines. A building may be divided from top to bottom, but the dividing line may have a "kink" or a "dogleg" in it. The division may be along what has been described as a broken vertical line, partly vertical and partly horizontal. Then one unit will, in part, lie over or under the other. Clearly, it would be absurd if every such deviation from a straight vertical line, however trivial or unimportant, were to take a unit outside the scope of section 2(1)(b)." "4 Section 2(2) provides how the concept of a "house" is to be applied in such "mixed" cases. The effect of this subsection is that if a material part of a (structurally attached) "house", ascertained in accordance with section 2(1), lies above or below a part of the structure not comprised in the house, then the enfranchisement provisions are inapplicable to that house. In this context "material part" must mean material part of the house, namely, of the unit identified as a house by application of section 2(1). This unit is to be excluded from enfranchisement by section 2(2) if, but only if, a material part of it lies above or below a part of the structure to which it is attached." "5 The criterion by which materiality is to be judged for this purpose must depend upon the purpose which section 2(2) is intended to serve. On this there has been some difference of judicial emphasis. I think the better view is that the purpose of the section is simply to avoid the absurdity mentioned above. The subsection is concerned to ensure that the right of enfranchisement is not lost by reason of the fact that a trivial or unimportant part of the house overhangs or underlies another part of the structure to which it is attached. The subsection achieves this result by excluding from the scope of the Act cases where a material part of the house lies above or below a part of the structure to which it is attached." "6 This suggests that in this context materiality calls for a broad assessment of the relative importance or unimportance of the part as a feature of the house. Does this part have the effect that the house as a whole overhangs or underlies the structure to which it is attached to a substantial, or important, extent? If, judged by this standard, the underlying or overhanging part of the house is immaterial, then the landlord's interests, if any, in the adjoining property are protected by section 2(5), not by exclusion of the whole house from enfranchisement."
"...the rule about vertical division was in need of qualification to deal with cases where part of the structure in that plane, such as a room or a cupboard, projected above or below another part of the same structure."
"If one then had to go on to consider the materiality of the part lying above or below a part of the structure not comprised in the house, then greater difficulty arises because it seems to me that having regard to the various ways in which their Lordships approached the question in the Malekshad case, not all of them suggesting the same criteria for judges in my position to adopt, there is considerable force in Mr. Radevsky's submission that the part of the wall which lies within the house is a material part of the house. Even though that part may not be financially important, in accordance with one of the criteria considered by Lord Scott (which I take to mean the sort of overhang or underhang which would provide space which could have an impact on the sale price for the property), nevertheless it is very significant structurally. It is the support for the flank of the house. If one were to take it away, as Mr. Radevsky submits, one would not even have the cube which a house normally consists of. It is one of the four walls. In terms of size, it may not be significant or material, but in terms of support for the house, it is. If I were to reach a conclusion on materiality, having regard to the structure of the house, then in my judgment the flank wall would be a material part."
"It is not a reference to a material part of the building of which the house forms part, nor to a material part of the structure to which the house or the part of the house is attached. And since the reference is to a material part of the house to be enfranchised, the materiality must depend, in my opinion, on the relationship between the part in question and the house as a whole. The relative size of the part may be a factor; the price- enhancing quality of the part may be a factor; the extent to which the part derives or provides support or protection from or for other parts of the house may be a factor. No doubt other factors might come into play in a particular case. And, as Lord Wilberforce made clear, the issue will be a largely factual one, an issue, as Stephenson LJ said, "of fact and degree"
"...the purpose of the section [2(2)] is simply to avoid the absurdity mentioned above. The subsection is concerned to ensure that the right of enfranchisement is not lost by reason of the fact that a trivial or unimportant part of the house overhangs or underlies another part of the structure to which it is attached. The subsection achieves this result by excluding from the scope of the Act cases where a material part of the house lies above or below a part of the structure to which it is attached."
"In Malekshad, the House of Lords found that a proportion of a basement area amounting to just over 2 per cent of the overall floor area of the house which lay beneath the adjoining property was not material and in consequence the tenant succeeded in his claim for that house. In Parsons, the overhang comprised approximately 10 per cent of the overall floor area and included a bathroom, a WC, a substantial part of a dressing room and half of a small bathroom; it was considered that this was clearly a material part on any test and the point was not argued in the House of Lords. As a general rule, it is thought that eaves, drainpipes, cupboards, box-rooms, water tanks, chimney breast and the like would not be material. However, the whole or any substantial part of any living room, bedroom, kitchen or bathroom would constitute a material part. Nevertheless, in each case it will be a question of fact or degree."
"If, judged by this standard, the underlying or overhanging part of the house is immaterial, then the landlord's interests, if any, in the adjoining property are protected by section 2(5), not by exclusion of the whole house from enfranchisement."
