"13. In this instance the basement would increase the number of storeys within the building, as the Council contend, but not in a manner which the GPDO provisions seek to address through that element of control. The overall height of the dwellinghouse, as enlarged, would be no different in relation to neighbouring properties than the existing building. Consequently, I conclude that the interpretation adopted by the Council is incorrect as it applies to this case. 14. Since I have concluded that the proposed basement would not have more than one storey, the further limitation contained in paragraph A.1(f)(ii) which is also relied upon by the Council, namely that it would be within 7m of any boundary does not fall to be considered."
"6. Therefore, although the proposed basement would result in development comprising more than one storey, as referred to in A.1(f), it would not be within 7 metres of any boundary of the curtilage of the dwellinghouse opposite the rear wall as this adjoining property is not a dwellinghouse but is part of the institutional use of the Royal College of Art. 7. The Council says that the enlarged part of the dwellinghouse would be within 7 metres of the boundary of the application dwellinghouse opposite the rear wall of the application dwellinghouse. That is, that the dwellinghouse referred to is the appeal site itself. However, this interpretation relies on inserting the words I have put in italic above and these simply do not exist in the GPDO and the words that are used in the Order must be given their ordinary meaning. Further, in the part of the TG relevant to Class A and the conditions specified in A.1, the guidance says that the enlarged part of the house "must be a minimum of seven metres away from the boundary of the land surrounding any house opposite"
"The carrying out of building, engineering, mining or other operations in, on, over or under land..."
"(f) Subject to paragraph (g), the enlarged part of the dwellinghouse would have a single storey and - (i) extend beyond the rear wall of the original dwellinghouse by more than 4 metres in the case of a detached dwellinghouse, or 3 metres in the case of any other dwellinghouse, or (ii) exceed 4 metres in height."
"'Original' means, in relation to a building existing on1st July 1948 , as existing on that date and, in relation to a building built on or after1st July 1948 , as so built."
"The consultation proposed that the volume allowance for rear extensions should be replaced with limits on how far an extension could extend from the rear wall of the property."
"6. The Council contends that the determination of the application merely represents its opinion on the matter. This is correct. However, when the Council has changed its approach and diverged from that adopted by other Council's [sic], that must call into question whether such a change was reasonable without due precautions. 7. The Council have not indicated any clear cause for this change in approach to the interpretation of the GPDO, save for a point of consistency, which is not entirely clear, and which, in my appeal decision, I have not accepted for reasons given there. 8. For the above reasons I find the Council's change of course to be inconsistent with its own former actions, those currently adopted by other Council's [sic], and unsupported by any legal authority or appeal determination. Accordingly, I find the action to constitute unreasonable behaviour as defined in guidance. That action resulted in an appeal to achieve a decision which, until recently, would have been the same one as the Council would have arrived at. The process has incurred the Appellant in unnecessary and wasted expense. Accordingly, the application for a full award of costs succeeds."
