While the loss of the building would not have a strong visual impact on the general character of the conservation area, the historical significance of the area as a collection of surviving buildings representing the evolution of the place from colonial times to the present day and demonstrating mid nineteenth century lifestyles would be adversely affected by the loss to a significant degree.
50 Mr Lonegan did not consider the building to be contributory and therefore concluded that it could be demolished provided the replacement building contributed to the setting of the conservation area.
51 In balancing the different heritage evidence, I find that there is sufficient evidence to demonstrate that the cottage contributes to the conservation area and is of sufficient heritage significance to warrant conservation within a redevelopment of the site.
52 Part of the significance of the conservation area is the evolution of residential use, which is demonstrated through a range of houses of different periods and styles reflecting the different social structure of the area. Grand sandstone houses are intermingled with workers' cottages or terraces. Trouton Street and its immediate area demonstrate this diversity.
53 Control B4.2 of the DCP recognises that small houses, particularly single storey and timber ones, are under increasing pressure for redevelopment and establishes the process for their retention or demolition.
54 The cottage satisfies criteria 1 and 2 of B4.2, being of heritage and streetscape significance.
55 While detailed evidence of an alternate scheme were not provided the experts agreed that the cottage could be retained as part of a viable redevelopment of the site as required by criterion 3.
56 The experts also agreed that the structural condition of the building did not warrant its demolition and met criterion 4.
57 Therefore it has not been demonstrated that the demolition of the cottage meets the requirements of B4.2 of DCP 2000.
58 As stated above, the cottage is of heritage significance sufficient to contribute to the conservation area and its removal, without tested justification, would adversely affect the heritage significance of the conservation area. The demolition of the item therefore does not satisfy cl 16(8) of LEP 2000 or meet the heritage conservation objectives in cl 15, including objective (d) "to allow compatible and viable adaptation and reuse of the fabric of heritage significance". It has not been demonstrated that the cottage cannot be reused or adapted into a viable redevelopment of the site that is compatible with the building itself and the conservation area.
59 I note that redevelopment of the site which incorporates the cottage may require a relaxation of some controls in the DCP including the Rear Building Location Zone and that such a proposal may have different impacts on residential amenity which would need to be assessed. However, the evidence before me is that this is reasonably feasible and without such an option being tested, the demolition of the cottage is not reasonable or justified. On this basis the application must fail.
Other issues
60 As this is a threshold issue I will not deal in any detail with the other main issues in the appeal, being the SEPP 1 objection to FSR development standard and the appropriate building envelope.
61 I accept the evidence of Mr Smith, the Court appointed town planning expert, that the non compliance with the FSR and the building envelope are interlinked. Essentially if the building envelope generated by a 6 m wall height is appropriate then the FSR non-compliance is justified whereas if the building envelope generated by a 3.6 m envelope is appropriate then the breach in FSR requirement would not meet the objectives of the standard set out in cl 17, i.e., to be complimentary and compatible and to achieve the desired future character of the area.
62 The desired future character for the area stated in the DCP envisages a single storey character and form over most of the slope from Darling Street to the bay by applying the 3.6 m control except for dominant corners.
63 The DCP recognises that in Campbell Street and east of Campbell Street two storey development is more common and that the 6 m wall height may be appropriate. This site, although to the west of Campbell Street, also demonstrates the typology of two-storey corner buildings with two-storey terraces stepping down from the corner with the rest of the street being single storey.
64 The site marks the transition between the existing two storey houses from Campbell Street and the single storey houses. If the site were to be redeveloped the question is whether it should be an extension of the two storey terraces or the single storey houses.
65 Mr Staas considered that the two storey proposal was appropriate infill development, although he stated that he had not examined this in relation to what the planning controls aim to achieve or the desired future character for the area.
66 Mr Smith considered the eastern alignment of the site and 8 Trouton Street opposite, represented the boundary between two storey and single storey development and that the proposal would represent an intrusion into the single storey section of the street. He recognised that 8 Trouton Street is two storeys but that it is detached, set back from the street and at a lower height than the adjoining terraces to the east and therefore forms a transition between the two storey and single storey part of the street.
67 Mr Smith considered that a 3.6 m wall height would provide a similar transition and was appropriate development on the site under the planning controls especially as it would also meet the FSR control for the site.
68 I accept Mr Smith's evidence that while the proposal is compatible and forms a continuation of the two storey terrace style development to the east it does not achieve the desired future character of the area which envisages a predominantly single storey character. The site is currently single storey and the appropriate termination of the two storey development is the existing terraces, which step down from the corner of Campbell Street. These terraces reinforce the corner. A further extension would result in a greater dominance of two storey elements in the streetscape, a feature not envisaged by the DCP.
Orders
69 For the above reasons the orders of the Court are:
1. The appeal is dismissed.
2. The development application (DA 04/0319) to demolish an existing cottage and outbuildings and construct two four level dwellings at 13 Trouton Street, Balmain, is refused.
3. The exhibits, except exhibits 1 and 2 may be returned.
4. No order as to costs.
