ii. a building certificate application under s 149 of the EPA Act (Appeal No 10360 of 2007).
2 The building certificate application seeks to rationalise a raised concrete slab used to park two cars. The slab has an area of about 186 sq m, its height ranges from about 300 mm above existing ground level at the eastern end to about 900 mm at the western end. The parking is accessed off Babbage Road via an existing access point. The slab was constructed without consent and was originally larger in size.
3 Following the site inspection on 14 March 2007, the applicant agreed to remove part of the slab to reduce its impact on the three trees along the eastern boundary fronting Babbage Road.
4 The development application initially included the slab with the addition of stairs and a balustrade as well as conversion of the existing garage into a rumpus room.
5 On the first day of the hearing, the parties agreed that no retrospective approval can be granted under a development application and therefore a building certificate application was required to rationalise the unapproved works, which should be excluded from the development application. Council raised no issue in relation to the other works proposed in the development application.
6 The site, its context, the history of the application and the planning controls are summarised in the Statement of Basic Facts.
7 The Court heard expert evidence on site from Mr Glendenning, planner for the applicant, Mr Ford, the applicant's arborist, Ms Rae, council's planner, and Mr Fenn, council's arborist. Ms Rae, Mr Fenn and Mr Antella, the applicant, also gave evidence in Court on 18 May 2007.
8 The main issue in dispute was the impact of the size and height of the slab on the character of the area and the tree closest to the driveway.
9 The parties disagreed on the correct manner to assess the building certificate application. Mr McKee, for the applicant, submitted that the considerations were limited to issues such as structural soundness. Mr Rigg, for the council, submitted that the broader application outlined by Bignold J in Ireland v Cessnock City Council [1999] 110 LGERA 311 should be applied. This is summarised more fully by Bignold J in Taipan Holding Pty Limited v Sutherland Shire Council [1999] NSWLEC 276 where his Honour at para 60 stated:
