“(1) In this Part “residential property” means— (a) a building that is used or suitable for use as a dwelling, or is in the process of being constructed or adapted for such use, and (b) land that is or forms part of the garden or grounds of a building within paragraph (a) (including any building or structure on such land), or (c) an interest in or right over land that subsists for the benefit of a building within paragraph (a) or of land within paragraph (b); and “non-residential property” means any property that is not residential property. This is subject to the rule in subsection (7) in the case of a transaction involving six or more dwellings.”
“Section 92B(1)(b) includes within the definition of residential property “land that is or forms part of the garden or grounds of a building within paragraph (a) (including any building or structure on such land)”
“ “Garden or grounds” includes land which is needed for the reasonable enjoyment of the dwelling, having regard to the size and nature of the dwelling. This will usually be a question of fact depending on the individual circumstances of each case.”
