Consideration
20There can be no doubt that what is proposed in respect of each of the three properties is a building separate from the existing dwelling house and on the same lot of land as that dwelling house. The question to be determined and that which calls for characterisation is whether or not the proposed structure satisfies the definition of "detached studio", understood in the context of the Complying Development SEPP.
21Despite the fact that cl 1.5 seeks to define the term "detached studio", that definition affords no assistance in assigning a meaning to the word "studio". Its defined attributes, namely that such a structure must be ancillary development, that it be habitable and that it must be ancillary to the dwelling house on the land is made clear. It is also apparent by reference to the other structures comprehended by the definition of "ancillary development" in cl 1.5 and which make reference to a "dwelling house", that what is intended by the concept of "detached studio" is not a further dwelling house.
22A "studio" would normally describe an area or space within a building and within which some separate activity is carried out by an artisan or artist. Whether use of the term "studio" is intended to be so specific in the present circumstances need not be determined and I do not confine my consideration to that concept. However, what must be apparent from the provisions of the Complying Development SEPP, particularly those that pertain both to the definition of "ancillary development" and the definition of "detached studio", is that whatever habitable structure is able to be built, it must be established in conjunction with an existing dwelling and it must be ancillary to that dwelling. So much is required by cl 3.5.
23Development that is "ancillary" to other development is a concept that is well understood in planning law. It identifies a structure or use, the purpose of which is subservient to some other development purpose against which it must be measured and which it must be seen to subserve. That is, it must be subordinate to the purpose against which it is being considered, in this case an existing dwelling house (Foodbarn Pty Ltd v Solicitor-General (1975) 32 LGRA 157 per Glass JA at 161). Likewise, the use of the phrase "in conjunction with" in the definition of "detached studio" identifies the need for there to be a functional nexus between the existing dwelling house on each property and the new structure to be erected.
24As I understand the submission made on behalf of Mr Trives, essentially it focuses upon the aspect of habitability and the fact that the building proposed in each case will be of a lesser area than that occupied by the existing or principal dwelling on each property as justifying its characterisation as a "detached studio". I can accept that a "studio", within the meaning of the Complying Development SEPP, is not necessarily confined to a single room. It is clear that it must be a room or perhaps rooms that by application of modern building standards, such as those found in the Building Code of Australia, provide sufficient space, height, light and air circulation so as to render the room "habitable" (cp definition of "habitable room" in cl 1.5 of the Complying Development SEPP). No question arises in the present case as to the habitability of the structures that are the subject of the complying development certificates. Nonetheless, questions of degree will arise as to the extent to which a proposed new structure satisfies the definitional requirements of the Complying Development SEPP when that Policy is read as a whole. Identifying the structure as "habitable" does not address all of the requirements of either the definition or of the Policy.
25Having regard to the Complying Development SEPP, what is apparent is that the intention of the drafter of the instrument cannot have been one to accommodate, under the rubric of "detached studio", something that is both separate from and can be used independently of the existing dwelling house on the land in respect of which the application is made. As the cases that have addressed the general concept of ancillary development make clear, comparison of areas of use where two purposes of use are shown to exist or to be intended is likely to have little relevance when determining whether one of those purposes is ancillary to or subserves the other (Foodbarn Pty Ltd v Solicitor-General at 161).
26Here, the separate building or "detached studio" in each case is capable of being used as a separate dwelling house or separate dwellings in the case of the Hornsby property. So much is acknowledged in the Statement of Facts that has been tendered in each case by agreement and which states at [6]:
"The structure approved under the CDC contains a unit comprising a suite of rooms which is capable of being used as a separate domicile."
When that statement is considered with the more detailed description that I have given to the building intended in each case and, more particularly, to the manner in which each such building is internally configured, there can be no doubt that these structures are, in truth, properly characterised as serving the purpose of separate dwellings or "dwelling houses" within the meaning of the latter expression found in cl 1.5 of the Complying Development SEPP. The meaning of the latter phrase is further informed by the definition of "dwelling" in the Standard Instrument (cf cl 1.5(2) of the Complying Development SEPP).
27Clause 1.18 of the Complying Development SEPP requires that to qualify as complying development for the purpose of the Policy, the proposed development must, among other things, be permissible with consent in the land use zone in which it is to be carried out. That is, for present purposes, it must be use for a purpose that is permissible within the R2 Zone under the Hornsby LEP. If it is not properly characterised as development for the purpose of a "detached studio" within the meaning of the Complying Development SEPP, then, having regard to the characteristics of each structure, it can properly be characterised as a form of housing accommodation, engaging purposes of development defined within the LEP. Relevantly, those definitions in the LEP potentially engaged are "dual occupancy detached", defined to mean two detached dwellings on one lot of land, or "secondary dwelling", which is defined to mean a self-contained dwelling that is established in conjunction with another dwelling, a principal dwelling, on the same lot of land and located within or attached to or separate from the principal dwelling (Dictionary to the LEP).
28I need not stay to wrestle with the distinction between a "secondary dwelling" and "dual occupancy" as defined in the LEP. Suffice it is to say that upon the proper characterisation of development in contemplation in each case before me, as reflected in the plans attached to the certificates signed by Mr Trives, it is apparent that the development proposed not only falls outside the "detached studio" definition in the Complying Development SEPP but also falls within either one of the definitions of "dual occupancy" or "secondary dwelling" in the LEP. If I am correct in that regard, as I believe I am, then cl 1.18 is not satisfied, with the consequence that the Complying Development SEPP is not engaged in the present case. As I have already recorded, neither development for the purpose of a "dual occupancy" nor for a "secondary dwelling" is permissible in the R2 Zone.
29I have already referred to cl 3.5 of the Complying Development SEPP as it identifies "ancillary development" to be development specified in the Housing Code. Clause 3.8 of the Policy also needs to be noticed. It provides that development specified for the Housing Code may only be carried out on a lot that "at the completion of the development will have only one dwelling house". If each of the three properties in question is developed in accordance with the complying development certificates issued by Mr Trives, completion of the "detached studios" in accordance with the plans that he has certified will result in more than one dwelling house on each lot. That being the case, cl 3.8 operates so as to exclude "ancillary development" specified in cl 3.5 from engaging the provisions of the Complying Development SEPP.
30Mr Astill, who appeared for the Council, also drew attention to the provisions of the State Environmental Planning Policy (Affordable Rental Housing) 2009 (NSW) (Affordable Housing SEPP) which addresses a particular form of dual occupancy or additional housing referred to as "secondary dwelllings" on a single allotment of land. That Policy identifies development of that kind as "complying development" but only if it complies with the standards fixed by the Policy. As Mr Astill submitted, it would be an odd result if what is presently proposed does not comply with the standards of the Affordable Housing SEPP for secondary dwellings, as is acknowledged to be the case in respect of the structures that are the subject of the complying development certificates, yet if Mr Trives is correct, those structures, comprising separate dwellings, would be complying development on the subject properties by dint of the Complying Development SEPP. Although there is some substance to that submission, I need not determine whether it justifies the result for which Mr Astill contends.
31I have identified three bases upon which the proposed "detached studios" do not engage the provisions of the Complying Development SEPP and therefore do not comprise development that is lawfully able to be the subject of the complying development certificates in question. First, development proposed in each case is not ancillary to the existing dwelling house on each property; that development does not comply with cl 1.18 of the Complying Development SEPP and further it does not comply with cl 3.8 of that instrument.
32For the reasons that I have expressed, the questions posed in each proceeding must therefore be answered in the following manner:
Proceedings 40215 of 2014
Q. "Did the First Respondent validly issue the Complying Development Certificate to the Second Respondent in relation to land at 14 Railway Parade, Hornsby on 22 January 2014?"
A. No
Proceedings 40259 of 2014
Q. "Did the First Respondent validly issue the Complying Development Certificate to the Second Respondent in relation to land at 231 Midson Road, Epping on 29 January 2014?"
A. No
Proceedings 40277 of 2014
Q. "Did the First Respondent validly issue the Complying Development Certificate to the Second Respondent in relation to land at 46 Pennant Parade, Carlingford on 5 February 2014?"
A. No
33In light of my answers to the separate questions posed for determination, it is clearly necessary for the Second and Third Respondents in each set of proceedings to be heard as to what, if any, orders should be made as a consequence of the proceedings having been instituted by the Council.
34It is agreed, on behalf of the Council, that the matter should stand over to 14 November 2014 for the purpose of directions being made as to the further conduct of the proceedings. The Council, however, now seeks an order that its costs in respect of the separate question be paid by the First Respondent, Mr Trives. Mr Gourlie, who appears for Mr Trives, makes no submission in opposition to that order. Accordingly I order the First Respondent to pay the Council's costs of and in connection with the determination of the separate question.
35The formal orders that I make therefore are:
(1)The separate questions posed for determination on 21 August 2014 be answered in the manner indicated in [32].
(2)The proceedings be stood over for further directions to Friday 14 November 2014.
(3)The First Respondent must pay the Applicant's costs of and associated with the determination of the separate questions.
