The proposed Floor Space Ratio (FSR) of the development is 4:1 which was prepared in accordance with the SREP at the time which imposed no FSR limit on residential development. The revised SREP applies an FSR of 3:1.
It is understood that the introduction of an FSR to residential development came about predominantly as a result of the following concerns:
· The practice by previous development to treat building envelope and height controls as the only framework for determining gross floor area without references to urban design, amenity and streetscape objectives.
· The practice of maximising development yield within the building envelope establishing a built form distinguished by excessive bulk, continuous and oppressive walls and facades and no attention to articulation scale, character and richness to the detriment of the broader urban design objectives for the Ultimo-Pyrmont Precinct.
Therefore in preparing this SEPP 1 Objection City West Housing is cogniscent of the concerns that resulted in the introduction of the FSR and has endeavoured to propose a development concept that accommodates these concerns.
City West Housing's grounds for objection to the application of the provision are as follows:
· The proposed development complies in all respects with the guiding principles contained within the revised UDP. Specifically:
- the scale of the proposed development ensures that the public domain, particularly Wentworth Park and surrounding streets is not significantly overshadowed as demonstrated in the shadow diagrams contained within this document.
- the building form is modulated within the building envelope to enhance streetscape context, promote visual character and richness and reduce building bulk and visual uniformity.
- building bulk, coupled with height and setbacks ensures that all principles with regard to privacy, environment and amenity are met, particularly though the provision of the courtyard.
- additional height is provided at the street corner to define the street block generating a visual landmark and clues within the urban environment, assisting legibility as well as streetscape character.
- the heritage significance of the adjoining pumping station is not compromised by the proposed development.
- views and vistas are identified and maintained where reasonably possible. This is discussed in detail in Section 4.5 below. Vistas through the site are provided and framed by the built form proposed.
- the facade of the development is rich in treatment and modelling, particularly in comparison to other contemporary residential developments.
- roof design is attractive and enhances, rather than erodes, the skyline.
· Therefore the proposed development meets the urban design principles of the UDP, particularly with regard to the articulation, bulk, scale, open space, modulation of roof form and breaking down of building mass.
· In other words the proposed development does not attempt to maximise the building envelope, negating the concerns generated by other developments, and consequently negating the need for, and deeming as unnecessary, the imposition of an FSR control in this particular development.
· Furthermore the achievement of the urban design principles contained within the UDP is reinforced through the preparation of a block study, for the surrounding development sites. The block study demonstrates that protection not only of the amenity of existing surrounding development but also future development of the north of the proposed development is achievable. The block study is presented in Section 4.5.
4.4.3 BUILDING HEIGHT
The proposed building height is 21.6 metres which exceeds the revised SREP height limit of 21.0 metres by a mere 0.6 metres (60 centimetres). To achieve this height and to maintain the number of affordable housing units with the development the ceiling height has been proposed to be 2.4 metres which falls short of the requirement of 2.7 metres.
It is understood that the revised building height controls within the Updated SREP were introduced to protect the quality of the public domain. This change came about as a response to the concerns being generated by development at the time as described in Section 4.4.2 above.
City West Housing's grounds for objection to the application of these provisions are as follows:
· The proposed development height of 21.6 metres to the ceiling of the top floor is not consistent throughout the whole development and is proposed to be located only on the corner of Wattle Street and Wattle Crescent. This reflects City West Housing Pty Ltd's commitment to satisfy the Update changes wherever possible. Thus the exposure of the part of the development above 21.0 metres to surrounding development (of a greater height) is minimal.
· The Shadow diagram demonstrates that there is no unreasonable impact on adjoining uses and development. In mid winter the effect of shadows cast by the building are clear of Wentworth Park and all neighbours after 12pm which is, we believe, a totally acceptable situation in the context of the winter season. In fact the adjoining high rise development incurs significantly greater shadow impacts on the proposed development than the other way round.
· City West Housing Pty Ltd is cogniscent of the intent behind the imposition of the new height control on development and has endeavoured to design the development to achieve the objectives within the intent. In this regard the design has been undertaken such that the bulk, mass and scale of the development complies in all respects, except height, with the SREP and UDP, resulting in minimal environmental impacts. Height is exceeded only in the corner of the development to the rear, and also achieves urban design objectives with regard to corner articulation.
· The portion of the development over 21.0 metres has negligible impact on view corridors out of the adjoining development. Similarly the orientation of the building ensuites that the view corridor and aspects are essentially unimpeded. Further more the Block Study for the remainder of the triangle reinforces the protection of view corridors and aspects above the proposed 21.0 metre height regulation.
· Overall the proposed development is consistent with UDP urban design principles to articulate, facades establish a distinctive building corner, step building heights and modulate built form in accordance with the principles outlined in S.4.4.2 above. The outcome is considered to be a good urban design solution for the site.
· The proposed development does not attempt to maximise the building height for the site, negating the concerns generated in other developments, and correspondingly negating the concerns for, and deeming as unnecessary, the imposition of a height limit of 21.0 metres in this particular development.
· Again reference to the Block Study in Section 4.5 demonstrates the protection of the amenity of not only surrounding development but future development also.
