24 Clause 21 of the LEP permits subdivision, with development consent. Clause 20B sets out the minimum allotment sizes. The provisions relevant to subdivision are those in cl20B(1) and (2). Clause 20B(1) applies to the 2A Zone, and thus to the site, and specifies a minimum allotment size for allotments resulting from subdivision of 400 sq m, and a frontage of at least 12 m. There is no equivalent provision to cl30(3) in the former LEP, which read:
30 Minimum allotment sizes
…
(3) The minimum size for an allotment that may be subdivided (whether or not by a strata plan) to create separate allotments for the dwelling comprising an attached dual occupancy within Zone 2A is 900 square metres.
25 In my view the omission of a clause in similar terms from the consolidated LEP is not significant, reading subclauses 20B(1) and (4) in the context of the controls provided in cl20B as a whole. Clause 20B(4) applies to determine when an attached dual occupancy development can be approved. Clause 20B(1) applies when the question is whether an allotment in the 2A zone (which may have a dwelling house or an attached dual occupancy, or an approval for either) can be subdivided.
26 In identifying what is the underlying object or purpose of the development standard imposed by cl20B(1), the starting point is the text of the clause. The applicant submits that the statement of "Purpose" at the end of cl20B is the underlying object or purpose of the development standard. The Council submits that this is to be ascertained by reference to those words, and by reference to the objectives of the zone and the aims of the LEP in order to understand what is meant by "local amenity".
27 The words appearing at the end of cl20B form part of the LEP: cl2A. As a statement of purpose, those words must be construed. I agree with the Council that in construing the phrase "protect and improve local amenity" it is appropriate to have regard to how the objectives of the 2A zone and the aims of the LEP address the desired local amenity, in particular the objectives in cl10(1)(b) and (c), and the aim in cl2(l) of the LEP.
28 Clause 20B(1) applies to all land in the 2A zone. In my view the area adopted by Mr O'Toole for consideration is too confined, and it is appropriate when considering "local amenity" to consider the site in the broader context of land in the 2A zone generally. I agree with Mr Harding that the relevant area for consideration of "local amenity" in this case is the area of 2A zoned land surrounding the site up to approximately 200-250m from the site, bounded by land zoned 2B to the east of the site (on the other side of Arden Street), and to the west at the intersection of Clovelly Road and Fern Street where there is a small area of land zoned 3B Local Business, and other land zoned 2B. This broader area of 2A zoned land contains a more diverse range of allotment sizes than the area identified by Mr O'Toole. The Director City Planning Report assessing the development application before the Council noted (at p9) that "the majority of allotments in the urban blocks within reasonable walking distance of the site have a larger land area and frontage than the proposal", and that less than half of the 243 allotments zoned 2A in the area bounded by Arden Street, Greville Street, Fern Street and Division Street had a land area of less than 260 sqm and/or a frontage width of less than 8m.
29 The provisions for minimum allotment size in cl20B of the LEP are the outcome of reviews of the previous planning instruments, which reduced the minimum allotment size for the 2A zone from 450sqm to 400 sqm. A Report by the Director City Planning (No 42 of 2005) (exhibit 4) stated:
Investigation was carried out on the capability of the ensuing 450, 400 and 350sqm allotments (from 900, 800 and 700 respectively) for accommodating a single dwelling of appropriate modern standard (see Figure J in the Issues Paper). This shows that as the land size decreases it becomes harder to achieve two dwellings on 350sqm allotments with good design outcomes (for example, providing for the parking in the design, & the percentage of hard paved surfaces increase). The 400sqm allotment achieves two dwellings that are more acceptable. This scale of subdivision would be on average 10% smaller than the average subdivision patterns, thus generally not likely to adversely affect these patterns. Assessment indicates that the 400sqm allotments can accommodate a single dwelling closer to modern proportions whilst meeting the general requirements of good design, including streetscape impact and sufficient parking provision, whilst providing a slightly higher opportunity for subdivision in the low density residential areas. A reduction to 800sqm is also consistent with the original recommendations in the draft LEP 1998 report. Altering the minimum subdivision allotment size requires amendment to the Randwick LEP 1998.
30 The Report noted (at p11) that under the then current provisions approximately 7,000 properties were able to develop attached dual occupancies, however the restriction on strata subdivision had limited demand for this form of housing with 114 applications being considered in the previous five years. The Report continued:
The subdivision (including strata subdivision) of attached dual occupancies is not permitted under LEP. Any variation that permits strata subdivision of attached dual occupancy is likely to increase the number of attached dual occupancy development applications substantially, that is subdivision would encourage a greater proportion of these 4,500 properties to be developed (almost 30% of 2A properties), as each dwelling can be sold separately in addition to renting or use by an extended family. The focus of this review is to provide reasonable opportunities for this housing type, where a high standard of design can be met and to continue the current focus on increasing density in areas that are most accessible to services and transport.
31 The outcome of the review supporting a 400 sqm minimum allotment for accommodating a single dwelling which can meet general requirements of good design while still providing some opportunity for subdivision in the lower density residential areas is reflected in the development standard imposed by cl20B(1).
