The evidence
28The conclusions of the written request are supported by Mr Rohan Dickson, the applicant's expert architect and urban designer who maintains that the height is appropriate. He states that the majority of the building is below the 15m standard and where the building exceeds the 15m standard, there are no adjoining buildings. In his opinion, the proposal also reflects the desired future character of the area.
29Mr Graham Brooks, an architect and heritage consultant also provided evidence for the applicant. He states that the proposed additions are sympathetic to the form and scale of the building and to the fundamental Beaux Arts composition. The proposal has adopted a best practice conservation approach by confining the majority of the new accommodation above the lesser and more recessive foyer component of the overall architectural composition.
30The proposal currently before the Court, as amended, has deleted the southern roof level apartment originally proposed for the southern side of the auditorium on the grounds that it may have been partly visible above the major architectural presentation of the Liverpool Street and Forbes Street elevations when viewed from the primary public vantage point at the intersection. The northern roof level apartment has been amended to reduce its height and set back further from the external wall lines of both the northern and western elevations. A new section of infill parapet, at a matching height to the existing parapet, has been introduced along the central section of the northern elevation to successfully screen the great majority of this apartment from views further north in Forbes Street. As a result, the roof level apartment is not readily visible above the main architectural massing of the auditorium. When it can be perceived from further north in Forbes Street, it is above the secondary northern or side elevation, which was treated with more restraint than the primary Forbes Street and Liverpool Street elevations.
31Ms Gabrielle Morrish, the councils expert architect and urban designer, maintains that any extensions or alterations to the building should be recessive and not attempt to dominate the heritage building, in terms of height. This calls for a sensitive response that should have lesser massing and height than the existing building and its ridgeline so that the appreciation of the ridgeline is not lost. The allowable height under LEP 2012 is 15m however the achievement of this height is not a given; it is a starting point against which the character and significance of the heritage item, the streetscape and the amenity of adjoining development needs to be balanced.
32In her assessment of the planning controls, the 15m height requirement for this site is specific and applies generally to only the site and another site to the north east. Other sites and heritage items around the site have different heights. For instance, to the immediate north, the height standard increases to 30m whereas it is lower on the other side of Forbes Street. Such specific height standards suggest careful strategic consideration of the height of the existing heritage buildings and the intent to keep the height less than or the same as the current building form. The existing ridgeline on the heritage former church is above 15m so the inference could be made that any redevelopment should be lower than the maximum existing height of the church.
33The application proposes a two storey extension over the foyer entry and a single storey extension partially intruding into the roof form of the auditorium to the north. The two- storey foyer extension is within the maximum height standard and is located facing Liverpool Street. Given this is the least developed part of the site, it is probably the most appropriate location for an addition, subject to issues of boundary proximity.
34The northern roof addition sits above the dominant form of the former church and intrudes into the roof space. It exceeds the height control by between 1.5m and 5.5m, based on information provided by the applicant. It is 'perched' up on the roof along with the proposed terraces and does not sit comfortably with the existing form of the church or the roof. Its location does not relate to the existing load bearing structure or its elements, instead it straddles the side bays of the church and extends over the main body of the auditorium. Its juxtaposition is awkward, above the height plane and does not respond to the existing structure and layout.
35The new parapet increases the bulk of the northern facade of the building purely to hide an extension that is above the 15m height standard. If the proposal were compliant with the height standard then the parapet would not be required as the addition would be much further back relative to the Forbes Street streetscape. Given the heritage values of this building, its location within a conservation area and in proximity to so many other heritage items, it is not considered reasonable to exceed the height standard and to do so in a way that is able to be perceived from the public domain.
36Overall. the northern addition locates new building form in a way that is not responsive to the design of the original building, interrupts the silhouette of the building and changes the silhouette where it is visible to the public domain in a way that reduces the significance of the heritage item.
37Ms Jennifer Hill, an architect and heritage consultant, also provided evidence for the council. She agrees with the comments of Ms Morrish and states that the breach of the height standard impacts on the heritage significance of the building. In her opinion, the reliance on the ridge height as the appropriate reference point for height is not appropriate as the building height is defined by the parapet.
38From a heritage perspective, Ms Hill opposes the extension of the existing parapet along the western facade of the building. In her opinion, and if the parapet was to be raised to the level proposed, the design should not mimic the existing parapet of the southern and eastern facades of the building but consist of a more contemporary design to distinguish the new parapet from the existing heritage parapet. As I understand her evidence, she did not oppose alterations to the building above the existing foyer although her evidence did not address the amenity impacts associated with the form proposed in this application although these impacts were addressed by Ms Morrish who raised considerable concern and which are addressed later in the judgment.
