Communal open space on the roof
21 DCP 64 requires 360m2 of communal open space for this proposal. The proposal provides 220m2, all of it on the roof. The Design Review Panel considered the provision of all of the communal open space on the roof inappropriate. Mr Dickson had the same view. In addition, he believed that there was no justification to reduce the communal open space required by DCP 64 to 220m2. Commissioner Bly commented on the communal open space as follows:
"As for the provision of communal open space, I recognise that it does not comply with the area requirement of the DCP. Despite this, with appropriate landscaping, structures and facilities and bearing in mind that it can be accessed from the lift, I expect that the roof top communal open space would be satisfactory. It will have a good outlook and, given its configuration and location towards the centre of the building, it will be relatively private."
22 It appears therefore that Commissioner Bly found that the area of the communal open space was adequate and that its location on the roof was appropriate. However, on reading the whole of his judgment, I am not able to conclude that the urban design aspects of the location of the communal open space, as well as its size, was a matter of dispute during the previous hearing.
23 In my opinion, a valid argument can be put for the reduced communal open space, though only in the 2(d) zone. If the building were four-storeys high (ie described in the DCP as high-rise unit development), DCP 64 would require only 180m2 of communal open space. The 2(d) zone allows four-storey buildings. Therefore, where an applicant proposes a three-storey building in the 2(d) zone, it is disadvantaged not only by the loss of a storey, but also by the larger communal open space requirement.
24 I turn to what I consider the major issue in this appeal, namely the location (rather than the size) of the communal open space. I accept Mr Dickson's opinion that in a low-density, low-key place like Toukley, placing it all on the roof is out of character. I note that this was also the opinion of the Design Review Panel. As for the resident objectors, the rooftop open space was a major reason for objection. While DCP 64 does not specifically state that the communal open space should be at ground level, this may be because the DCP's authors assumed that this was understood without being stated.
25 I accept that open space on the roof has some advantages for the building's future occupants in that it provides breeze and views of the water. The disadvantages, however, are more significant. First, the use of the roof as open space incorporates a shading structure that significantly adds to the perceived height of the building and makes it appear as four-storeys high, thus negating the restraint the applicant has shown in proposing a three-storey building. Second, it requires a higher lift tower than would be the case if the roof were non-trafficable. Third, where communal open space is at ground level, at least some apartments overlook it. Residents enjoy communal open space not only when they use it but also when they look at it from their apartments.
26 However, the main reason for rejecting the provision of all communal open space on the roof is that it is unsympathetic to Toukley's character, whether existing or future. Rooftop open space may be appropriate in Kings Cross or the CBD, but not in Toukley, even in a high-density zone of Toukley.
27 I am strengthened in the above conclusion by the objectives nominated for open space in the Residential Flat Design Code. These are:
· Landscape design
· Daylight and ventilation access to apartments
· Visual privacy
· Opportunities for recreation and social activities
· Water cycle management.
28 With the exception of the fourth, the objectives suggest that when the authors of the Code speak of open space, they mean open space on the ground.
29 I accept that the applicant interpreted Commissioner Bly's judgment as condoning the rooftop communal open space. As I have stated, it is unclear whether the urban design aspect of the issue was fully explored in the previous hearing. Since that judgment, however, the Design Review Panel and the Court-appointed expert, Mr Dickson have recommended that the proposal be redesigned to delete the communal open space on the roof and provide it at ground level. If the Court were to disregard that advice and find that rooftop location of communal open space is acceptable in an area like Toukley, it would give rise to a planning principle, whether expressly stated or not, that it is acceptable everywhere. The true planning principle should be the reverse.
