Any further work to the facades of the building should match as closely as possible the existing detailed relationships of cladding and framing and the present materials.

    Doors, Windows & Grilles
The pattern and detail of the existing doors, windows and grilles on the building facades are an integral part of the original design and its subsequent modification. Minor alterations to original door and window openings are acceptable provided they do not significantly affect the visual perception of the original design aesthetic.

Policy 26  Before considering any changes to the pattern of fenestration on the building an assessment of the potential impacts of such changes should be undertaken to ensure that they do not significantly affect the appearance or character of the place.

Policy 27  Any new doors, windows or grilles should respect the appearance, proportions and materiality of the original components existing façade to minimise visual impacts on the exterior of the RBA Head office building.

    Roof
The roof of the RBA building was designed as a 'floating' plane generally devoid of significant plant and equipment.  Roof works carried out in c2001 included the construction of lift overruns associate with two new lifts servicing Levels 16 to 20 together with safety barriers. Some further minor modification of the roof area is acceptable provided this approach is maintained.

Policy 28  Additional structures or equipment can be located at roof level provided they are set back from the building edge sufficiently to avoid breaking the skyline in important views from pedestrian areas in Martin Place.

Policy 29  Any new major items of equipment or structures on the roof should where possible be contained in simple enclosures screened from view of overlooking buildings.

Garden
The garden adjacent to the Macquarie Street boundary was designed to contain examples of Australian native flora.  The original plants and trees have progressively been replaced with exotic species, and are no longer consistent with the original design philosophy of the building and its setting.  Restoration of the original concept is desirable where possible, taking into consideration the microclimate of the garden, the pollution and water requirements of any new plantings.

Policy 30  Future changes to the Macquarie Street Garden area should consider the original design concept as an opportunity to regain significance.

8.2.4            Interior Fabric
The internal character of the building is an area of secondary heritage significance with all of the spaces and finishes of the original design having been substantially modified in the 1990s refurbishment to provide safe working environments, meet changing needs and replace worn and damaged finishes. Further changes to aspects of the interior of the building should be guided by an assessment of the potential significance of the individual parts and components.
