7 The applicant contends that the constraint of the conversion provides a basis as to why the development should be approved and that the mitigating circumstances are that the location of the unit block is excellent in terms of its proximity to beaches and other open space areas. I have considered the relevant clauses under the LEP suffice to say have I refer to cl 12(1)(a) where the consent authority must be satisfied that the development is consistent with any relevant general principles of development in Pt 4. Part 4 in particular contains cl 64 and this requires that private open space be provided for all housing clearly set apart for private use and directly accessible from a living area of the dwelling and capable of serving as an extension of the dwelling for relaxation, dining, entertainment, recreation and children'/s play. Private open space must be capable of receiving not less than two hours of sunlight between 9 am and 3 pm during the winter solstice for 50% of the area of private open space. In the case of ground level private open space, other than for apartment style housing, in particular the minimum area and dimensions of private open space required for different forms of housing (that is dwellings other than apartment style) at ground level is 35 sq m. For apartment style which council does not concede that this particular proposal would fall under, it is 10 sq m. with a minimum dimension of 2.5 sq m. There are various other elements in terms of the standard such as privacy, building bulk, conservation and energy, etc., that the consent authority must take into consideration in an assessment of the application.
