Findings
44Section 96(2)(a) of the Act relevantly states - A consent authority may...modify the consent if it is satisfied that the development to which the consent as modified relates is substantially the same development as the development for which the consent was originally granted...
45In this instance, the original approved development was for the construction of a new two storey, two bedroom residential dwelling on a vacant site. The relevant conditions of consent required the dwelling to be constructed in accordance with the approved plans and, amongst other things, the roof of the ground floor to the rear to be non-trafficable at all times. The approved plans clearly show a sloping metal skillion roof over the rear of the living room extension at the rear of the dwelling and a sliding window 1500mm high x 2300mm wide with external timber plantation shutters.
46Both solicitors have referred to Moto Projects and the need for a comparison having regard to the qualitative, as well as quantitative, differences between the developments and the context and circumstances in which the development consent was originally granted.
47It is my opinion that the proposal for an a upper floor deck accessible through full glass double doors to be screened on three-sides by a 1.5m glass balustrade and on one side by planter boxes planted with 1.5m high Lillypillies is a significant departure from the original approved development. Therefore I am not satisfied that the proposal is substantially the same development as the development for which the consent was originally granted . I agree with Talbot J in Satellite Group that is appropriate in the circumstances of this matter to consider the upper rear deck to be a 'critical element' of the overall development; the particular circumstances being the site's location adjacent to a heritage item and in the vicinity of many more, with the attendant impacts on the visual integrity of the heritage conservation area.
48The proposed deck and associated privacy screens materially change the approved development. The qualitative consequences of the modification would be to change the acknowledged sympathetic design aspects of the original approved development and create a structure that, in my view, is obtrusive and incompatible with its heritage setting.
49Even if I accepted that the proposal was substantially the same, I am not convinced on the merits and other matters to be considered under s79C of the Act. In regards to the applicant's argument that the deck is necessary to achieve better compliance with the area of private open space set down in cl 1.2.2 SSDCP, I agree with the council's assessment of the original development application that the ground level courtyard is acceptable given the overall size of the site. I also agree with Mr Girvan that it would be practically impossible for almost any property in the immediate locality to comply with 45m 2 of ground level private open space given the very small average lot size. Indeed, the site is one of the largest lots in the block and has significantly more ground level open space than any other lot in the block. The open space is designed to be a fully accessible extension of the ground floor living area. The proposed modification is a balcony off a bedroom and not a living room and therefore its use as private open space would appear to be secondary and limited in its value.
50Mr Darroch cited the decision by Tuor C in Yazbek to approve a roof top terrace in order to provide private open space. The proposal included the use of 1.8m high glass balustrades and landscaping to minimise the visual and acoustic impacts to nearby residents. In that decision, the Commissioner considered the amenity of the occupants and that of the neighbours and found the roof top terrace to be acceptable subject to conditions restricting its use. However, the circumstances of that case are distinctly different to the circumstances of the site subject to this appeal. The Yazbek site was a converted substation that occupied the entire site and therefore no opportunity existed for open space at ground level. As already noted, at least 30% of the site in Little Napier Street is accessible ground level open space.
51I am similarly unconvinced about the weight to which Mr Darroch's arguments for the need for some private (screened) open space to take advantage of the winter sun can be given. I am not satisfied that sunlight to a small balcony off a second bedroom for an unquantified duration for a limited part of the year justifies the proposal. It would seem to me that the landscaping required for privacy would inevitably limit the transmission of sunlight. The approved rear courtyard is north facing and, not withstanding the proximity of the nearby dwellings and the street trees in Albion Street, in the context of its surroundings would appear to receive adequate solar access.
52Therefore in regards to 1.2.5 in SSDCP concerning upper level decks, I agree with the council that while the proposed privacy screens and landscaping would help in restricting direct overlooking and assist acoustically, I do not consider that the existing ground level private open space is so limited or constrained that it establishes the threshold of need for an upper level deck.
53Whilst minimising impacts on residential amenity are one component of the objective pertaining to the design and location of upper level decks, it is equally important that the design does not compromise the design of the building. Mr Darroch contends that the proposed modification reads as a transitional element between the flat facades of the heritage buildings to the west and the balconies on the two contributory buildings to the east and therefore does not comprise the design. With respect to the upper level decks on the buildings to the east, the fact remains that these balconies were approved (even if not immediately constructed) in the early 1980s prior to the current SSLEP, SSDCP and SHDCP. While Mr Darroch also pointed out other examples of upper level decks and balconies in the vicinity, some approved more recently, each case must be determined on the facts and circumstances relevant to the particular proposal.
54The other relevant controls are found in the SHDCP and the heritage provisions in cl 22 of SSLEP. I find that the proportions and materials of the proposed deck and screening do not respect and compliment the alignment and finishes of the heritage items to the west and therefore the vicinity controls in cl 2.1 and 2.2 of SHDCP are not satisfied. For the same reasons, I am not satisfied that the relevant objectives and provisions of Part 4 of SHDCP in regards to the character of the heritage conservation area are met. While I agree that infill development should not necessarily copy or replicate neighbouring heritage buildings, it nonetheless needs to be sympathetic in its bulk, setback, materials and so on. It is acknowledged that the original design achieved an acceptable balance between contemporary features and harmony with the heritage items. I find that the proposed modification will compromise that balance and result in unacceptable visual bulk and form that will not be sympathetic to the materials and form of the heritage items.
55In this regard, non-compliance with those elements of the SHDCP leads to non-compliance with clauses 12(a), 12(c) and 22(e) of the SSLEP, and on this basis, consent cannot be granted for the carrying out of the proposed development.
56With respect to the applicant's argument that creating additional private open space will improve the amenity for the occupants of the dwelling and as such should be given as much weight as the needs of other nearby residents, I consider the private interests of the applicant do not outweigh public interest in retaining the integrity of the conservation area and adjoining heritage items.
