Overall, the quality of the construction of the building and extensions is generally poor and details of the existing foundations are unknown. On this basis, we consider that any refurbishment and/or upgrading of the existing structures could not be certified to comply with current Structural Engineering and Building Code of Australia Standards.
27 It is not unusual that a pre-1900s building may not meet current standards. I do not accept that it would not be feasible to upgrade the building to meet these standard but the question is whether it is reasonable to do so given the likely costs and the significance of the building. Council did not raise issue with the Structural Report and I accept Dr Pollard's evidence that while the two storey element contributes to the Singleton Conservation Area, its contribution when weighed against the poor condition of the structure is insufficient to require retention of the structure.
28 The question then becomes whether the replacement building will have an acceptable impact on the Singleton Conservation Area and the heritage items in the vicinity. The experts have agreed that the amended proposal is generally acceptable, although Dr Pollard maintained his concern about the setback to George Street.
29 I am satisfied that the form of the building is appropriate in the streetscape, which contains a mixture of one and two storey buildings with no consistent building setback to the street alignment. The single storey scale of the building will provide views of the former Mechanics Institute building and is similar in scale to the single storey building, which adjoins the former Mechanics Institute building to its south (76 George Street). The proposal is built to the street alignment. While I acknowledge Dr Pollard's opinion that the proposal could be setback from George Street to open up the corner and provide views of the former Mechanics Institute building, I accept that the proposal maintains the alignment of the existing building and has a similar setback to 76 George Street. The former Mechanics Institute building is setback further from the street and lined by two side laneways. This arrangement frames the former Mechanics Institute building and I accept Ms Azzi's opinion that this maintains the existing historical relationship between the site and the former Mechanics Institute and is appropriate in the streetscape.
30 The original proposal was tilt up slab construction, which Dr Pollard considered would not achieve appropriate detail or be characteristic of the Singleton Conservation Area. The proposal has been amended to be brick construction in different colours or rendered with details such as exposed downpipes and recessed faux windows. It is important that the colours, materials and details indicated on the plans (exhibit D) are implemented in the construction of the building and a condition is imposed to require this. There are also no details of the windows and doors on the George Street façade or the faux windows (decorative fillet lines) so a condition has been included which requires these details to be submitted for approval.
31 DCP 2009 identifies that views along Kent Street to the former Patrick Plains Shire Council are important to maintain. The proposed building does not obscure any views of this building. The rear of the site is currently vacant and unsightly. This area will be used for parking and as the drive though area for the bottle shop. The experts agreed that, subject to satisfactory landscaping, the view to former Patrick Plains Shire Council would be acceptable. A condition had been imposed to require planting of trees on the site and within the front planting area to screen and soften the parking area and the view to the former Patrick Plains Shire building.
32 The experts agreed that proper integration of signage into the building is important to the streetscape and is a requirement of DCP 2009. During the hearing they indicated appropriate location for signage (exhibit 16) but no details or size of the signage were specified. Due to the lack of detail I have not incorporated this as part of the approval and a condition has been imposed that a further signage strategy is required to be submitted for approval, which provides details of the signage. Clearly, an illuminated sign box projecting from the façade of the building would not be appropriate and any signage that faces or is viewed together with the former Mechanics Institute building should be carefully considered.
33 The proposal, if implemented in accordance with the conditions, will have an acceptable impact on the Singleton Conservation Area and the heritage items in the vicinity and meets the requirements of LEP 1996 and DCP 2009.
