“The City Council has considered your application and grants consent for the works referred to below subject to the conditions and in accordance with the plans submitted.”
“You are advised that you cannot fully demolish the rear elevation of the mews house and must implement the permission in accordance with the drawings approved …”
“(16) For the purposes of this Group, the construction of a building does not include— (a) the conversion, reconstruction or alteration of an existing building … (18) A building only ceases to be an existing building when: (a) demolished completely to ground level; or (b) the part remaining above ground level consists of no more than a single façade or where a corner site, a double façade, the retention of which is a condition or requirement of statutory planning consent or similar permission.”
“37. Counsel for HMRC placed great emphasis on the proposition that the planning consent needed to contain an ‘explicit condition’ that the relevant walls should be retained. We are not entirely clear whether this contention extended to the proposition that there would be no such explicit condition if the consent required the building to be constructed in accordance with the plans (as it did), and the plans indicated that the two walls should be retained. If, however, the contention was that extreme we reject it. 38. There is no requirement that the condition be ‘explicit’. There must simply be a condition or requirement that the walls be retained. In this context, we believe that the notion of a ‘condition or requirement’ is any term of the planning consent, compliance with which is required in order for the development to comply with the provisions of the planning consent, and to be lawful. In this case, if the indication of the Planning Officer in the 2009 letter is right to indicate that the plans did indicate that the North and East walls were to be retained, then since the consent required the development to be conducted in accordance with the plans, we decide without hesitation that the retention of the two walls was effected pursuant to a required condition. 39. We actually believe that the Planning Officer was instrumental in indicating that it was the North and East walls that should be retained. Even however if it had been the Appellant who had reluctantly volunteered that these two walls should be retained prior to the giving of the planning consent, and if it was thus the Appellant who had indicated the retention of the walls on the plans submitted, when the Planning Consent required the works to be undertaken ‘in accordance with the application and accompanying plans submitted by you’, it thereby became a condition of the construction of the new house under the relevant planning consent that the walls be retained. As the planners said on more than one occasion, if the walls had not been retained, the consent would have been void, the construction of the proposed house would have been unlawful, and all this would have been because a condition of the planning consent had been breached.”
