The site and the development application
5The site on which the building that is the subject of the development application stands is substantial. It has an area of about 4,299m². It is irregularly shaped with two, relatively narrow, separate frontages to New South Head Road, Double Bay and with a rear or southern frontage of about 7m to Edgecliff Road. The site is said to be a consolidation of three former lots. The rear or southern section of the site falls steeply from Edgecliff Road, although this section of the site is, in turn, elevated above the site's northern section closer to New South Head Road.
6There are three buildings located upon the site. The northern section of the site contains six two storey townhouses while the central section of the site is occupied by a three storey residential flat building. Towards the southern section of the site is a seven storey residential flat building (the tower building). Apartment 15 comprises the penthouse of the tower building.
7The Council maintains property records and property identification systems on a computer database. That database records the address of apartment 15 for rating purposes as being 15/325 New South Head Road, Double Bay. Apartment 15 is lot 15 in Strata Plan 58002. The Council's database for the common property held by the owners of Strata Plan 58002 shows the address for that property also to be 325 New South Head Road, Double Bay. Further, a printout from the Council's property database indicates the Double Bay address for proprietors of lots in Strata Plan 58002 to be their respective apartment numbers at either 325 or 335 New South Head Road, Double Bay. It seems that the western arm of the site that has frontage to New South Head Road is assigned the street number 325, while the eastern arm of the site fronting New South Head Road has assigned to it the number 335.
8At the request of the applicant I carried out a site inspection in company with the legal representatives of the parties. This, so it was submitted, was to assist me in understanding the evidence given as to the separation of the tower building from New South Head Road, the topographical features of the site, the proximity of the tower building to Edgecliff Road and the appearance of buildings on the site from that road.
9The site inspection revealed, as recorded in the transcript, that when viewed from Edgecliff Road, there was a gated entry to the site, apparently providing access to site residents and vehicular access to the tower building. The number "353" is clearly visible and is fixed to the post from which vehicular access gates are swung. The tower building is the only building apparent on the site when viewed from Edgecliff Road.
10From the gate at the address 325 New South Head Road, being the location of the western arm of the site boundary to that road, all three buildings located on the site are clearly visible. From the forecourt to the property numbered 335 New South Head Road, being the eastern arm of the site having frontage to that road, the townhouses together with the tower building are clearly visible.
11The printout from the Council's property database for each of apartment 15 and the common property must be noticed. In addition to identifying the street address of each, being the address which was said to be the subject of rate assessment, the following is recorded:
"Heritage item
LEP Heritage Item AKA 353 Edgecliff
The land to which this certificate relates, being the lot or one of the lots described in the corresponding application, is shown in the Council's records as being situated at the street address described on page 1 of this certificate. That street address is or contains, or is part of, a heritage item listed in a schedule in the local environmental plan (as amended from time to time) that applies to the land. That plan describes the street address as being 353 Edgecliff Road, Double Bay."
12Woollahra Local Environmental Plan 1995 (the LEP) is the principal planning instrument controlling development upon the site. Schedule 3 to the LEP lists heritage items in respect of which special controls are imposed. Included in that Schedule under the street address "353 Edgecliff Road Edgecliff" is a Cook Pine. This is the heritage item identified on the printout from the property data pertaining both to apartment 15 and the common property of Strata Plan 58002.
13The development application in respect of which the impugned development consent was granted was an application lodged with the Council on 7 May 2008. The development application form described the property that was the subject of the application as "335 New South Head Road Double Bay". At some time subsequent to preparation of the development application form by its author, the following words have been added to the address "AKA - 325 NSHRD - D. Bay".
14The development application was accompanied by a statement of environmental effects. The opening paragraph of that document commences as follows:
"Details of the Proposal
The proposed project at 335 New South Head Road/353 Edgecliff Road, Double Bay consists of an Alterations and Additions [sic] to the top level of an existing apartment block."
15The architectural plans lodged with the application and ultimately made the subject of development consent describe the address of the property in their title block as -
"Apt 15, St Neots Estate 335 New South Head Road Double Bay NSW".
16Evidence was given on behalf of the Council as to the maintenance of property records identification on the computer database. Apart from the matters to which I have earlier referred it was indicated that if one portal known as E-View Mapping was interrogated with the address 353 Edgecliff Road, no property outline was provided. If the system was interrogated by that same address through the other available portal, namely that known as "Authority", records for properties with the address 335 New South Head Road, were generated.
