45 Ms Laidlaw addressed the breach of the FSR under the planning principles of Super Studio v Waverley Council [2004] NSWLEC 91 and Tenacity Consulting v Warringah Council [2004] NSWLEC 140. Following Super Studio , "…the acceptability of an impact depends not only on the extent of the impact but also on reasonableness of and necessity for the development that causes it." She noted not only the breach of the FSR but also the breach in the side setbacks of the first floor extension under the Leichhardt Development Control Plan 2000 , (DCP2000). She considered that the proposal would result in a "…generous level of accommodation for an inner city lot" and that the balcony exacerbates the impacts. She noted that the views that would be impacted upon were those from principal indoor and outdoor living areas consistent with Tenacity . She noted that from these areas in No 17 Rose Street and to a lesser extent from Noes 15 and 13 Rose Street the extension would block the district view both from a seated and standing viewpoint.
46 Justice Lloyd in Winten Property Group Limited -v- North Sydney Council, NSWLEC 46, 6 April 2001 paras 22 - 26 set out the test for and SEPP1 objection. His Honour at para 26 stated that in applying the principles of Hooker Corporation Pty Limited v Hornsby Shire Council (NSWLEC, 2 June 1986, unreported):
…it seems to me that SEPP1 requires answers to a number of questions (not necessarily in the following order). First, is the planning control in question a development standard? Second, what is the underlying object or purpose of the standard? Third, is compliance with the development standard consistent with the aims of the Policy, and in particular does compliance with the development standard tend to hinder the attainment of the objects specified in section 5(a)(i) and (ii) of the EPA Act? Fourth, is compliance with the development standard unreasonable or unnecessary in the circumstances of the case? Fifth, is the objection well founded? In relation to the fourth question, it seems to me that one must look to see whether a development, which complies, with the development standard is unreasonable or unnecessary, as noted by Cripps J in the Hooker Corporation case.
