12 In my assessment, the visual impact of the proposal is important in terms of what that desired element on bulk and scale is trying to achieve, considering that the other controls in section 3.2 are complied with. In this context, submissions were made to the planning principles in PDE Investments No 8 Pty Ltd v Manly Council [2004] NSWLEC 355, wherein Tour C said:
48. The question of whether a building envelope can be filled when the FSR control would produce a smaller building is one that arises from time to time in Court proceedings. The following planning principles are therefore of assistance:
i. FSR and building envelope controls should work together and both controls and/or their objectives should be met.
ii. A building envelope is determined by compliance with controls such as setback, landscaped area and height. Its purpose is to provide an envelope within which development may occur but not one which the development should necessarily fill.
iii. Where maximum FSR results in a building that is smaller then the building envelope, it produces a building of lesser bulk and allows for articulation of the building through setbacks of the envelope and variation in building heights.
iv. The fact that the building envelope is larger than the FSR is not a reason to exceed the FSR. If it were, the FSR control would be unnecessary.
13 It seems to me that the current case can be distinguished because the proposal comfortably complies with the building envelope controls, which indicates the amount of structure anticipated above ground. However the exceedence of the FSR arises due to the extensive floor space created in the basement.
