Note: In this context 'site area' refers to the surface of the adjoining lot without regard for any building on it but taking into account its natural ground levels."
22 The shadow diagrams in evidence demonstrate that, at midday on 21 June, the shadow cast by the proposed development on the properties to the south-east and south-west of the site (in excess of that which would be cast by a 1.8 metre high boundary fence in any case) occupy only 5 square metres and 45 square metres, respectively, out of total site areas of 1080 square metres. Even taking into account the shadow cast by the fence, the shadow impact is well within the Acceptable Development criterion. In accordance with cl 3.9.1 of the RCodes, the development is therefore "deemed to meet the relevant Performance Criteria", which include that "development designed with regard for solar access for neighbouring properties".
23 Although nothing turns on it in this case, given that properties to the east and west of the site have not, as yet, been developed in a similar way to that proposed in the present application, I note that Acceptable Development criterion A1 of the design for climate requirements of the RCodes is drafted such that cumulative impact of overshadowing is not a relevant factor. In particular, the provision uses the words "its shadow". Given that, in other cases, while an individual development might not cast a shadow in excess of 25 per cent of the site area of a neighbouring property, cumulatively adjoining development might cast well in excess of 25 per cent, consideration should be given to whether the relevant criteria of the RCodes should be amended to address cumulative impact.
24 Although the proposed development conforms to the relevant provisions of the RCodes in relation to the impact of building bulk and overshadowing on adjoining properties, cl 16 of TPS 3 also requires the respondent, and the Tribunal on review, to have regard to "the orderly and proper planning of the locality" and "the preservation of the amenities of the locality". In accordance with the definition set out above, "amenities" would relevantly include avoidance of excessive bulk and scale of built form and reasonable access to direct sunlight. Although, in having regard to "the preservation of the amenities of the locality", the fact that a development conforms to a relevant provision of the RCodes is significant, it is not in itself determinative of the cl 16 consideration.
25 In the present case, the respondent submitted that, even if the development conformed to the RCodes, the siting of a 26 metre long building proximate to a southern boundary in an area zoned for redevelopment of adjoining sites was unacceptable.
26 In my opinion, the amendments made to the plans in November 2004, and the further amendment by way of condition proposed during the hearing, have made the development acceptable in terms of its bulk and scale. In particular, although the proposal involves an unbroken built form of approximately 26 metres in length, the built form has been set back in three planes. The highest section of built form has been set back furthest. The closest section of built form, while set back in a constant plane, has been reduced by 500mm in height, such that the eaves height of this section would project above the fence line by only 1.3 2.5 metres. The western proposed dwelling has been stepped down the east-west slope such that the roof form would not present as a single, continuous form, but rather as two different sections. The difference in the eaves heights of the two sections is, taking into account the proposed condition, approximately 1.6 metres. The bulk and scale of the proposal is further mitigated by the fact that the property to the south-east has been filled with boundary retaining walls, such that it is notably higher than the site, and the site adjoins two separate properties to the south, such that neither property would be exposed to a direct view of the full bulk and scale of the proposed built form.
27 In consequence, I am satisfied that the development would not give rise to an unacceptable visual impact in terms of building bulk when viewed from either property to the south.
28 I am also satisfied that, although the proposed building would plainly form part of the surrounding built environment, it would not detrimentally affect the development potential of either adjoining lot such as to warrant its refusal. Although I accept that redevelopment of the adjoining properties is likely to involve north-facing living areas and open space, I am satisfied that each of the lots could be developed for two or three dwellings in accordance with the zoning notwithstanding the proposed development.
29 I am satisfied that, although the proposed development would cast a shadow over a part of the adjoining properties in mid-winter, that impact is not unacceptable, either in terms of present use and enjoyment of those properties or the likely form of redevelopment of the properties. In particular, I am satisfied that each of the adjoining properties could be developed in the form of two or three dwellings with appropriate solar access notwithstanding the proposed development.
30 I note, for completeness, that in the original formulation of this issue in its notice of refusal, the respondent relied on its policy DBH1 Urban Design and Streetscape Guidelines. I accept the applicant's submission that this document is inapplicable in the present case. The express objective of this policy is "to conserve and enhance areas of architectural or historic character whilst encouraging harmonious development within the existing authentic character and appearance of the traditional residential areas of Fremantle". In my opinion, the area in question could not be said to be of "architectural or historic character". I do not accept Mr Jack's evidence that, because the southern side of Stack Street has "an established residential form" or "residential character" it is an area of "architectural ... character". In my opinion, "architectural ... character" requires more than a collection of disparate, domestic, architectural forms.
