‘(2) The supply in the course of construction of- (a) a building … intended for use solely for a … relevant charitable purpose; … of any services related to the construction other than the services of an architect, surveyor or any person acting as a consultant or in a supervisory capacity.’
‘The two-stage test for determining whether the works carried out constituted an enlargement, extension or annexe to an existing building is well established. It requires an examination and comparison of the building as it was or (if more than one) the buildings as they were before the works were carried out and the building or buildings as they will be after the works are completed; and the question then to be asked is whether the completed works amount to the enlargement of or the extension or the construction of an annexe to the original building (see Customs and Excise Commissioners v Marchday Holdings Ltd.[1997] STC 272 at 279). I must however add a few words regarding how the question is to be approached and answered, for this has been the subject of some lack of clarity (if not confusion) in a number of the authorities cited to me and it is the failure to approach and answer the question in this case in the correct way which flaws the decision. First the question is to be asked as at the date of the supply. It is necessary to examine the pre-existing building or buildings and the building or buildings in course of construction when the supply is made. What is in the course of construction at the date of supply is in any ordinary case (save for example in case of a dramatic change in the plans) the building subsequently constructed. Secondly the answer must be given after an objective examination of the physical characters of the building or buildings at the two points in time, having regard (inter alia) to similarities and differences in appearance, the layout and how the building or buildings are equipped to function. The terms of the planning permissions, the motives behind undertaking the works and the intended or subsequent actual use are irrelevant, save possibly to illuminate the potentials for use inherent in the building or buildings.’
