        4.1             Site Description
        The site is formally described as Lot 143 on RP88934, covering an area of 506 m2, with frontage to
        Bottlebrush Avenue along the south-western boundary. At the time of the investigation a two-storey
        house occupied most of the front half of the site, with a concrete driveway providing direct access off
        Bottlebrush Avenue.
        Based on a visual assessment, the existing building was noted to be in fair structural condition exhibiting
        no obvious signs of major distress (e.g. cracking, misalignment, etc.). However, some
        dilapidation/distress was evident across the existing driveway, retaining walls and fencing, which
        appeared to be related to age, poor construction and possibly consolidation of the upper loose sands.
        Residential unit developments and houses occupied properties to the north, east and west of the site. It
        appeared that these surrounding unit buildings comprised mostly at grade carparking, with the lower
        level partially excavated into the hillside.
        A recent aerial image of the site and immediate surrounds is shown in Text Figure 2 below.
