A quick check of LBH's planning history confirms that planning permission (ref. P/2013/1850) was granted on 28th October 2013 for the "erection of a single storey extension to provide lounge, dining, kitchen and staff offices" to Danehurst, which sounds like the site you are referring to.At first glance I would point out that there are quite a number of pre-commencement conditions requiring additional information to be submitted to and approved by the Council prior to works commencing, none of which appear to have been discharged.
