The bulk of the proposal (impact on 59 Gardyne Street)
24 The council's Statement of Issues expresses the concern with the proposal's bulk in terms of excessive FSR. The permissible FSR is 0.51:1, while the actual FSR is between 0.52 and 0.53:1, so the difference is minor. A reduction to 0.51:1 would not change the perceived bulk.
25 I note that a FSR of 0.51:1 is not consistent with maintaining the existing character of Gardyne Street. If the council intends to maintain the area at its existing scale (ie at the scale of those buildings that have not yet been redeveloped), it should impose a FSR at or below 0.4:1. The permissible FSR of 0.51:1 suggests that the council envisages a certain densification in the area.
26 Mr Wilson based his submission on this issue entirely on the proposal's impact on its southern neighbour, Mr Pether's and Ms Mitchell's property at No 59. It is common ground that in midwinter the proposed building would overshadow the northern window in No 59. There would be some sunlight at other times of the year, but it would be fair to say that the impact on the northern sunlight to No 59 would be extreme.
27 No 59 is set back about 1.5m from the common boundary. The second floor of the proposed building is set back partly 1.7m and partly 2m from the common boundary. The council's controls allow a setback of 900mm. The proposal's setback is thus more than twice that required by controls. To provide three hours of sunlight to the northern window of No 59, the proposed building would have to set back about 5m, at least on the upper floor.
28 In Pafburn v North Sydney Council [2005] NSWLEC 444, I summarized the criteria for assessing impact on neighbouring properties, as follows:
· How does the impact change the amenity of the affected property? How much sunlight, view or privacy is lost as well as how much is retained?
· How necessary and/or reasonable is the proposal causing the impact?
· How vulnerable to the impact is the property receiving the impact? Would it require the loss of reasonable development potential to avoid the impact?
· Does the impact arise out of poor design? Could the same amount of floor space and amenity be achieved for the proponent while reducing the impact on neighbours?
· Does the proposal comply with the planning controls? If not, how much of the impact is due to the non-complying elements of the proposal?
29 I apply the above questions to the proposal's impact on No 59. As I have said before, the impact on the northern window is extreme. However, in the context of the whole dwelling at No 59, the impact is somewhat less, since it has an open plan and receives light and amenity from the east, where there are panoramic views of the ocean. As regards the reasonableness of the proposal, one has to have regard to the general development around the site. In the context of the development around, a 5m setback from a side boundary, which would be required to maintain reasonable solar access to No 59, would be unusual. While on this 20m wide site it would be possible, on narrower sites, such as No 55A, it would not be practicable.
30 I turn to the third question, that of vulnerability to impact. A north-facing window 1.5m from a side boundary is extremely vulnerable to being overshadowed. As regards the fourth question, that of good design, I note that Mr Pethers suggested an entirely different design from the proposal. While there was no assessment of the floor space in the alternative design, I suspect that it had less floor space than the proposal. In any case, the alternative design was not a modification, but an entirely different design. The answer to the fifth question is that the proposal complies with the planning controls, apart from the small increase in the FSR, which does not have an impact on the solar access of No 59.
31 The application of the above principles suggests that it would be unreasonable to refuse this application on the grounds of its impact on the solar access of No 59. I note that No 59, which is itself under reconstruction, is a more modest building and more in sympathy with the character of the old parts of the area than the proposal. However, in order to justify a refusal of the application on those grounds, it would have been necessary for the council to adopt controls that permit the alterations and extensions to no 59, but not the new building on No 57 (and others of a similar bulk). There are no such controls, and therefore a refusal of No 57 would not be justified.
