17 As to cl 10.5, it was submitted by Mr Beech, on behalf of the appellant, that this clause means that if any one of several buildings not in conformity with the scheme should be destroyed, or damaged to the specified extent, none of the buildings on the lot may be repaired or rebuilt, altered or added to without special approval and none of the land on which the non-conforming use was being carried on may thereafter be used otherwise than in conformity with the scheme, without the special approval of council. In other words, it was submitted that cl 10.5 extinguished all non-conforming use rights in respect of the whole parcel of land in the event that any one building on the land was destroyed or damaged to the specified extent. I do not think cl 10.5 has this meaning. It is true that the first part of the clause refers to "building" in the singular and the second part refers to "buildings" in the plural, but, in my opinion, the clause is intended to impose restrictions only with respect to the destroyed or damaged buildings themselves and only with respect to that part of the land actually occupied by that or those damaged or destroyed buildings. The phrase "the buildings shall not be repaired or rebuilt ... ", etcetera, clearly refers to buildings "destroyed or damaged".
