The proposal achieves four (4) hours of sunlight to approximately two-thirds of the rear private open space of the southern adjoining dwelling at No. 6. The majority of the rear open space is in full sunlight between noon and 3 pm in mid-winter. In my opinion, that meets the objectives of DCP No 1.
14 Even if the private open space was limited to the paved area with direct access off the sunroom, Mr Crane considered the increase in overshadowing to be acceptable particularly when compared to the solar access already lost by the boundary fence and to the impact that would result even from a single storey addition set back 1.7 m from the boundary.
Findings
15 The principal issue in this case is the impact of the two-storey component of the proposal, which extends beyond the rear western façade of 6 Dawn Street. The element contains bedroom 1/ensuite. It extends 3.68 m and is set back 4.55 m from the common boundary between 6 Dawn Street and the site. The proposal was amended to increase the setback of this element to reduce the impact of overshadowing and visual bulk on the adjoining property.
16 The private open space of 6 Dawn Street comprises a paved area with a washing line, which is directly accessed off the sunroom and is approximately 6 m wide. There is also a grassed area to the west of the sunroom that is about 3 m wide. Mr Griffin stated that the paved area is primarily used.
17 The paved area will receive almost no sun until about 10.15 in mid-winter. This area is currently shaded at this time of year until after 9 am but the proposal will increase the shadow. From after 11 am, about 50% of the paved area will be in the sun and after 12 almost all of the area. The solar access to the grassed area will not be affected by the proposal.
18 "Private open space" and "principal private open space" are both defined in the appendix to the DCP. Clause 4.5.7 refers to private open space, which would include all of the area to the rear of 6 Dawn Street. Even if the definition of "principal private open space" is accepted, I consider that both the paved and grassed areas would be included in that definition as both areas are private and have direct access to a living area. Although not utilised by the Griffins, both areas could provide amenity as useable open space.
19 Solar access to at least two thirds of the combined open space area will be maintained. Solar access to the paved area will be reduced but not to any significant extent as at least 50% of the area will receive sun from about 11 am in midwinter. While I recognize that this change is of concern to the Griffins, it is not unreasonable given the planning controls nor is it unreasonable when the principles in Parsonage v Ku-ring-gai [2004] NSW LEC 347 and Pafburn v North Sydney [2005] NSW LEC 444 are applied.
20 In particular, the proposal is reasonable when considering the extent of solar access to be lost as well as how much is to be retained. 6 Dawn Street is to the south of the proposal and is therefore vulnerable to impacts. This is recognised in cl 4.5.7 of the DCP, which permits less than the 4 hour requirement on sites with an east-west orientation. Even with this constraint the proposal maintains 4 hours of sunlight to the private open space of 6 Dawn Street.
21 The proposal has been amended to address overshadowing impacts. It provides considerably greater rear and side setbacks than required by the DCP and is consistent with the form and likely impacts of development anticipated by the DCP.
22 If Council is concerned that two-storey elements should be excluded from the rear of properties, this should be explicit in its planning controls. I note that the contentions raised in response to the earlier proposal did not raise the deletion of the two storey section of the proposal, rather that it should be set back further from the boundary fence. This has been achieved and the overshadowing impact is acceptable.
23 The height, setback and articulation of the proposal will also not result in any unreasonable visual impact when viewed from the adjoining property.
24 In relation to the other issues raised by Mr Griffin, I accept the assessment in Council's reports.
25 The proposal meets the objective in Hurstville Local Environmental Plan 1994 "to preserve and enhance the character and amenity of established residential areas" and complies with both the numerical controls and the objectives of s 4.5 in the DCP.
Orders
26 The orders of the Court are therefore:
1. The appeal is upheld.
2. The development application for alterations and additions at 4 Dawn Street, Peakhurst is approved subject to the conditions in Annexure A.
3. The exhibits, except Exhibit 5, 6 and B are returned.
