THE LAND AND
ENVIRONMENT COURT
OF NEW SOUTH WALESMurrell C
11 June 2004
JUDGMENT10029 of 2004 Kevin Masling v Ku-ring-gai Council
1 This judgment is for an appeal concerning a development application submitted to Ku-ring-gai Council for a dwelling house at the property known as No. 22 Slade Avenue, Lindfield. These proceedings commenced as an on site hearing. At that time the development application was not satisfactory and the Court gave the applicant the opportunity to submit an amended development application. This significantly lowered the level of the garage and ensured that the building did not read as a three storey dwelling from the street.
2 Other amendments included the driveway, the front fence, and the upper storey. Following an adjournment he development application came back to the Court with an amended plan and the council has had the opportunity of assessing same as well as the council’s development assessment consultant, Ms Laidlaw who provided comments to the Court. The Court in many respects agreed with many of her concerns and further amendments were then required to the plans.
3 The plans recently submitted to the Court and received on 8 June 2004 are in accordance with the discussions held on site and further discussions and concerns expressed on the last occasion when we met in court. An amended landscape plan was also provided with the development application known as L1C and this also satisfies the landscaping requirements of council’s development control plan.
4 The proposed dwelling it is noted is in excess of council’s development control plan for dwelling houses in terms of the floor space ratio. The Floor Space Ratio (FSR) in the Development Control Plan is approximately 0.381, the subject dwelling is 0.461 and that is significantly over the FSR. However, I am satisfied in terms of the amendments that have been carried out, the reduction in the height of the dwelling and the landscaping, that the proposed dwelling will sit comfortably on the land and will not be unsatisfactory in terms of its presentation to the street.
5 It was submitted for the applicant that there were no objections to the proposal, however, that is not the test for the Court. The Court must be assured that the proposed dwelling in terms of its built form and outcome are acceptable and contribute positively in a streetscape context having regard to council’s controls and the zoning of the subject land. The subject land is zoned for the purposes of residential dwellings and it is noted there are also some multi unit developments in and around the area. The general character of the area is single dwellings on large allotments.
6 The streetscape presentation and a contribution to the leafy vegetative amenity of the area is important to the character of the area and should be conserved in developing this part of the municipality of Lindfield. Opposite the subject site there is a reserve that is clearly used by the public as well. Therefore the subject site can be viewed from the public domain of the street and reserve.
7 The Court in terms of the variations and amendments that have been done to the plans is now satisfied that the proposed development is one that is worthy of approval. And in my assessment there is no reason why a consent should not be granted.
8 I acknowledge in my judgment that the council has been most cooperative in its approach to this matter and its comments have certainly contributed to the amended application that is now acceptable.
9 The applicant expressed concern on the last occasion that we met about his frustrations with the lengthy process. On that occasion it was pointed out that the council’s controls must be a focal point in the formulation of developments as well as in the assessment of developments. The applicant on that occasion indicated that it had compromised on numerous matters. The applicant may have what it considers compromised but at the same time in the Court’s assessment it is important that development makes a positive contribution and the Court must give genuine, proper and real consideration to council’s controls.
10 The process that we have embarked upon has resulted in a development which is now satisfactory and as I stated both parties have contributed to what the Court now considers to be a satisfactory outcome.
11 On the basis of my assessment the orders of the Court are;
- 1. The appeal in respect of the property known as No. 22 Slade Avenue, Lindfield, is upheld in part.
2. The development application submitted to Ku-ring-gai Council, and as amended as shown in: the plans prepared by Arch-Serv, Architects & Project Managers, Issue “C” dated 8 June 2004; the amended landscape plan L1 ‘C’ prepared by Wallman Partners Pty Ltd; and Exhibit H, the schedule of materials and finishes, is approved subject to the conditions contained in Annexure “A”.
3. The exhibits except for 1, G and H are returned.
