“(16) For the purpose of this Group, the construction of a building does not include (a) … (b) any enlargement of, or extension to, an existing building except to 40 the extent the enlargement or extension creates an additional dwelling or dwellings; or 4 (c) … the construction of an annexe to an existing building.”
“(2) A building is designed as a dwelling or a number of dwellings where in relation to each dwelling the following conditions are satisfied (a) the dwelling consists of self-contained living accommodation; 10 (b) there is no provision for direct internal access from the dwelling to any other dwelling or part of a dwelling; (c) the separate use, or disposal of the dwelling is not prohibited by the term of any covenant, statutory planning consent or similar provision; and 15 (d) statutory planning consent has been granted in respect of that dwelling and its construction or conversion has been carried out in accordance with that consent.”
“The two stage test for determining whether the works carried out constituted an enlargement, extension or annexe to an existing building 40 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 5 asked is whether the completed Works amount to the enlargement of or the construction of an extension or annexe to the original building … I must however add a few words regarding how the question is to be approached and answered. First the question is to be asked as at the date of the supply. It is necessary to examine 5 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. 10 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, the uses for which they are physically capable of being put and the functions which they are physically capable of 15 performing. The terms of planning permissions, the motives behind undertaking the works and the intended or subsequent actual use are irrelevant, save possibly to illuminate the potential for use inherent in the building or buildings.”
“… regard must be only to the physical character of the buildings in course of construction at the date of the relevant supply and that the subjective intentions on the part of Mr and Mrs Cantrell as to their future use, their subsequent use and the terms of the planning 25 permission regulating their future use are irrelevant, save only in so far as they throw light upon the potential use and functioning of the buildings.”
“The reference to an ‘annexe’ in Note (16) when compared with the 35 references to ‘enlargement’ of or ‘extension’ to the existing building introduces a different concept. Thus they may be physically separate so that the connection between the two is by way of some other association. But the Tribunal seems to have thought that any association is enough. In my view that cannot be right. If there were a 40 sufficient association between building A and building B, on the Tribunal’s conclusion each would be an annexe of the other. So to hold would ignore the plain inferences to be drawn from the use of the word ‘annexe’. An annexe is an adjunct or accessory to something else, such as a 45 document. When used in relation to a building it is referring to a supplementary structure, be it a room, a wing or a separate building.”
“The terms of planning permissions, the motives behind undertaking the works and the intended or subsequent actual use are irrelevant, save 30 possibly to illuminate the potential for use inherent in the building or buildings.”
“It is unnecessary to reach any concluded view on that question to decide this case.”
