“(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.” and “non-residential property” means any property that is not residential property.”
“when considering whether land forms part of the … grounds of a building, a wide range of factors come into consideration; no single factor is likely to be determinative by itself; not all factors are of equal weight and one strong factor can outweigh several weaker contrary indicators; where a number of contrasting factors exist, it is necessary to weigh up all the factors in order to come to a balanced judgment of whether the land in question constitutes ‘garden or grounds’. This part of the guidance also refers to a number of factors which are individually discussed in other parts of the Manual but states that the list of other factors will not necessarily be comprehensive and other factors which are not mentioned there might be relevant.”
“One must, in addition, look at the use or function of the adjoining land to decide if its character answers to the statutory wording in s116(1) - in particular, is the land grounds “of” a building whose defining characteristic is its “use” as a dwelling? The emphasised words indicate that that the use or function of adjoining land itself must support the use of the building concerned as a dwelling. For the commonly owned adjoining land to be “grounds”, it must be, functionally, an appendage to the dwelling, rather than having a self-standing function ... use for a “commercial” purpose is a good and (perhaps the only) practical example of commonly owned adjoining land that does not function as an appendage but has a self-standing function.”
