Land and Environment Court of New South Wales CITATION : Handley v Pittwater Council [2010] NSWLEC 1167 APPLICANT Roger Handley and Dianne Handley PARTIES : RESPONDENT Pittwater Council FILE NUMBER(S) : 11018 of 2009 CORAM: Brown C KEY ISSUES: DEVELOPMENT APPLICATION :- demolition of an existing dwelling and the construction of a new dwelling - breaches of the council requirements for building envelope, site coverage, side building lines, retaining walls, visual impact and private open space Environmental Planning and Assessment Act 1979 LEGISLATION CITED: Pittwater Local Environmental Plan 1993 Pittwater 21 Development Control Plan DATES OF HEARING: 23 June 2010 DATE OF JUDGMENT: 6 July 2010 APPLICANT Mr G Green, solicitor SOLICITORS Pikes Lawyers LEGAL REPRESENTATIVES: RESPONDENT Mr N Eastman, barrister SOLICITORS Mallesons Stephen Jaques JUDGMENT: THE LAND AND ENVIRONMENT COURT OF NEW SOUTH WALES Brown C 6 July 2010 11018 of 2009 Roger Handley and Dianne Handley v Pittwater Council JUDGMENT 1 COMMISSIONER: This is an appeal against the refusal by Pittwater Council (the council) of Development Application No. N037/09 for the demolition of an existing dwelling and the construction of a new dwelling at 413 Whale Beach Road, Whale Beach (the site). 2 The contentions raised by the council relate to breaches of the council requirements for building envelope, site coverage, side building lines, retaining walls, visual impact and private open space. Early contentions relating to building height, view loss, building colours and materials, eaves, visual privacy and solar access where not pressed by the council following the submission of amended plans or conditions acceptable to the applicant. 3 I have found that the breaches of the council requirements are not individually, or collectively sufficient to warrant the refusal of the development application. The site 4 The site is Lot 286 in DP 16362. The site is generally rectangular in shape with a street frontage of 15.68 m, a northern side boundary of 47.29 m, a southern side boundary of 53.425 m and an area of 810 sq m. The rear boundary has a frontage to the Pacific Ocean. 5 The site is occupied by a multi-level dwelling that steps down the steeply sloping site. There is a separate garage near street level and an accessible structure containing a bedroom at the lowest level. 6 The area is dominantly residential in character with the property to the north being undeveloped and the property to the south developed with a single dwelling house. The eastern side of Whale Beach Road, in the vicinity of the site, slopes steeply from the road and has expansive views of the ocean and some locations towards Palm Beach and Barrenjoey Headland. Relevant planning requirements 7 The site is zoned Residential 2(a) under Pittwater Local Environmental Plan 1993 and the proposed development is permissible with consent in this zone. State Environmental Planning Policy No. 71-Coastal Protection applies although the council raised no contentions in relation to these plans. 8 Pittwater 21 Development Control Plan (the DCP) applies and contains provisions for the erection of a dwelling house. The relevant sections are Section D12.8 - Building Envelope, Section D 12.10 - Site Coverage - Environmentally Sensitive Land, Section D12.6 - Side and Rear Building Lines, Section D12.13 - Construction, Retaining walls, Terracing and undercroft areas, Section D12.14 - Scenic Protection Category One Areas and Section C1.7 - Private Open Space. 9 Section A4.12 addresses the Palm Beach Locality. The site is within this designated area of the DCP. Many of the DCP requirements refer to the desired future character of this area and the principle elements from the description in Section A4.12 are: - low density with a maximum two storeys in a landscaped setting, - integration with the landform and landscape, - development below the tree canopy, - bulk and scale to be minimised, - future development should respect the horizontal massing of existing building forms, - development on slopes will be stepped down the slope and be integrated with the landform and landscape, and - site disturbance will be minimised. 10 Section A1.10 provides the structure of the DCP. Relevantly, the DCP provides Outcomes which are a list of the outcomes that the development control is seeking to achieve, Controls which are generally numerical requirements that a proposed use/development should satisfy to achieve the outcomes of the development control and Variations which outline the circumstances in which consideration can be given to the variation to a control. The evidence 11 Expert town planning evidence was provided by Mr Greg Boston for the applicant and Ms Joanne Marshall for the council. Mr William Zuccon, the project architect provided a design statement. Building Envelope Control 12 Section D12.8 provides for development to be sited within an envelope projected at 45° from a height of 3.5 m from the side boundaries. 13 The outcomes in Section D12.8 are: * To achieve the desired future character of the Locality. (S) * To enhance the existing streetscapes and promote a building scale and density that is below the height of the trees of the natural environment. * To ensure new development responds to, reinforces and sensitively relates to spatial characteristics of the existing natural environment. * The bulk and scale of the built form is minimised. (En, S) * Equitable preservation of views and vistas to and/or from public/private places. (S) * To ensure a reasonable level of privacy, amenity and solar access is provided within the development site and maintained to neighbouring properties. (En, S) * Vegetation is retained and enhanced to visually reduce the built form. (En) The evidence 14 Ms Marshall states that the non-compliance is unacceptable. Compliance is appropriate given that the form of development on the adjoining vacant land is unknown at this stage. Any screening provided by the trees on the adjoining vacant land does not form part of the application and should not be considered. Ms Marshall further states that the concessions available in the DCP for eaves or shading devices do not apply in this case because of the substantial structure of the loggia and also the other non-compliances with the requirements in the DCP. 15 Mr Boston states that the DCP provides for variations to the building envelope, on a merit basis, where the building footprint is situated on a slope over 30%. On this basis, Mr Boston concludes that a variation is appropriate for a number of reasons including the extent of the breach which he states: - is minor and exacerbated by the site topography, - is limited to shading and balustrade elements with all wall elements fully compliant, - will not contribute, to any discernible or appreciable extent to the bulk and scale of the building when viewed from any adjoining residential property or the public domain, - satisfies the relevant outcomes in Section D12.8, and - will not result in the loss of any deep soil planning opportunities. Findings 16 The extent of the non-compliance with the building envelope was shown on a diagram attached to the joint statement of Mr Boston, Ms Marshall and Mr Zuccon. While there are non-compliances on different levels of the dwelling, Ms Marshall states that the only area of concern is on Level 1. In this location, part of the loggia floor and roof and balustrade are outside the building envelope. 17 The outcomes considered relevant by Ms Marshall and Mr Boston related to minimising bulk and scale, preservation of views, privacy, amenity, solar access and vegetation retention. Variations to the control are available where the slope is over 30% and where the non-compliance relates to eaves or shading devices. There was agreement between Ms Marshall and Mr Boston that the site is over 30% so the opportunity for variation is available. 18 I agree with Ms Marshall that the loggia area could not reasonably be defined as eaves or shading devices however I agree with the overall conclusions of Mr Boston. The area of non-compliance is relatively small and involves only a part of the loggia structure. The loggia is open on its two sides although with a roof and could not reasonably be seen to have the same bulk and scale as the dwelling proper. I am satisfied that the non-compliance has no meaningful impact on the bulk and scale of the dwelling. I am also satisfied that the non-compliance with the control raises no issues in relation to views, privacy, amenity, solar access and vegetation retention. 19 For the same reasons, I do accept that the non-compliance could be read as being inconsistent with the future desired character of locality. The proposed dwelling appropriately steps down the site, minimises site disturbance and is integrated as well as possible with the landform and landscape given the steep topography of the site. 20 While there is a non-compliance with the control, I satisfied that the outcomes for the control are achieved by the proposed development. Consequently, the non-compliance with the building envelope control would not be a reason to refuse the development application. Site Coverage Controls 21 Section D12.10 provides for a maximum site coverage of 40%. If the outcomes of the control are achieved, a variation to this control is available for impervious areas less than 1 m in width (i) and up to 6% of the total site area for "impervious landscape treatments providing these areas are for outdoor recreational purposes only (e.g. roofed or unroofred pergolas, paved recreation areas, patios, pathways and uncovered decks no higher than 1 m above natural ground level)" (ii). 22 The outcomes in Section D12.10 are * Achieve the desired future character of the Locality. (S) * The bulk and scale of the built form is minimised. (En, S) * A reasonable level of amenity and solar access is provided and maintained. (En, S) * Vegetation is retained and enhanced to visually reduce the built form. (En) * Conservation of natural vegetation and biodiversity. (En) * Stormwater runoff is reduced, preventing soil erosion and siltation of natural drainage channels. (En) * To preserve and enhance the rural and bushland character of the area. (En, S) * Soft surface is maximised to provide for infiltration of water to the water table, minimise run-off and assist with stormwater management.(En, S) The evidence 23 Ms Marshall states that the proposed dwelling is excessive in bulk and scale as the built structures have a site coverage of 40.66%, this exceeding the permitted site cover of 40%. Ms Marshall calculates the total site coverage at 46.14%. This exceeds the control of both the maximum 40% with a 6% variation permitted under the control. 24 Mr Boston agrees with Ms Marshall that the built structure has a site coverage of 40.66% however Mr Boston calculates the total site coverage (including impervious landscape treatment areas) at 44.04%. In his opinion, if tested against the outcomes of the control, the variation even on Ms Marshall's calculations can be justified. Findings 25 The extent of the site coverage relied on by Mr Boston and Ms Marshall was shown on a plans attached to the joint statement of Mr Boston, Ms Marshall and Mr Zuccon. 26 Mr Boston addresses each of the outcomes to reach his conclusion that a variation can be supported. I do not propose to repeat his written evidence beyond stating that I accept his conclusions and that a variation can be justified. Importantly, the variation is extremely small and in my opinion, the concerns expressed by Ms Marshall are overstated. If the 40% site coverage requirement is used to measure building bulk then a non-compliance of 0.66% (or 4.9 sq m) would not be discernible when looking at the dwelling from any location. A 46% site coverage is clearly contemplated for the proposal by Section D12.10; being a single dwelling on residential zoned land. The difference in the calculations of Ms Marshall and Mr Boston centred on a relatively small paved area land located near the entry and car turntable. Ms Marshall includes this area in her calculations whereas Mr Boston excludes the area on the basis that it can be used for "outdoor recreational purposes". Even if Ms Marshall's approach is adopted (and I do not necessarily accept this), the difference in impact to a complying development (that is, 46% site coverage or 1.1 sq m) is miniscule and would have no measurable or visual impact on any of the matters identified in the outcomes to this section. 27 Even if the site coverage was 46.14%, I am satisfied that the outcomes for the control are achieved by the proposed development. Consequently, the non-compliance with the site coverage control would not be a reason to refuse the development application. Side Building Lines Control 28 Section D12.5 provides setbacks for the side and rear building lines. The side building line requires "2.5 to at least one side; 1.0 for other side". There were no issues with the front or rear building line. 29 The outcomes in Section D12.5 are: * To achieve the desired future character of the Locality. (S) * The bulk and scale of the built form is minimised. (En, S) * Equitable preservation of views and vistas to and/or from public/private places. (S) * To encourage view sharing through complimentary siting of buildings, responsive design and well-positioned landscaping. * To ensure a reasonable level of privacy, amenity and solar access is provided within the development site and maintained to residential properties. (En, S) * Substantial landscaping, a mature tree canopy and an attractive streetscape. (En, S) * Flexibility in the siting of buildings and access. (En, S) * Vegetation is retained and enhanced to visually reduce the built form. (En) * To ensure a landscaped buffer between commercial and residential zones is established. The evidence 30 Ms Marshall acknowledges that there are a number of non-compliances with the side building line however she raises issue only with the 1 m setback of Level 1 on the southern elevation and the 1 m setback to the loggia on Level 3. Her concerns relate to the inability to properly landscape these areas. Ms Marshall maintains that Section D12.5 requires that each side setback should be consistent, that is either 2.5 m or 1 m and not a combination of both. A consistent 2.5 m setback to one boundary would allow for the provision of landscaping (especially canopy trees) to be provided between buildings. This allows the built form to nestle below the established tree canopy levels, and not allow the built structures to dominate the landscape especially when viewed from a distance. Ms Marshall also questions whether there is sufficient deep soil to guarantee the longevity of the landscaping. 31 Mr Boston notes that one outcome identified in Section D12.5 provides for flexibility in the siting of buildings and access. This allows the setting of setbacks that are responsive to site constraints and opportunities, the juxtaposition of adjoining development, natural site features and built form context. In his opinion, the setbacks address these matters in an appropriate manner. The 1 m setback to the southern boundary is responsive to the view lines available over the roof of this lower element from the adjoining property at 411 Whale Beach Road. Further details have been provided that indicates sufficient soil depth is available for the proposed landscaping. A 2 .5 m setback is provided for the rest of the southern boundary where it adjoins the adjoining dwelling. In relation to the 1 m setback of the loggia, Mr Boston states that this is consistent with Section D12.5 in that a 2.5 m setback is provided on the opposite boundary. 32 Mr Boston further states that sufficient area is available for canopy trees and in his understanding; the council requires a minimum of three canopy trees to be provided (Section C1.1). The landscaping plan indicates that these trees have been provided and does not include the additional planting provided on the road reserve. Findings 33 If the variations to the site setbacks identified by Ms Marshall tested against these outcomes, I agree with conclusions of Mr Boston. There is some considerable merit in the approach adopted by Mr Boston of providing setbacks that are appropriate to the particular circumstances of the setback. It is an overly simplistic approach to require a specific setback for the whole side boundary without considering the consequences of the setback on the natural topography and any adjoining development. I accept Mr Boston's evidence that sufficient area is still available for the provision of canopy trees and that sufficient soil depth is available for the provision of landscaping on Level 1 adjoining the southern boundary. Clearly, it is not necessary for every part of every setback to make provision for canopy trees given the requirements in Section C1.1. 34 Given an outcome that contemplates "flexibility in the siting of buildings", I am satisfied that the outcomes for the control are achieved by the proposed side setbacks. Consequently, the non-compliance with the site coverage control (even if the approach of a consistent setback to each side boundary is adopted) would not be a reason to refuse the development application. Retaining walls, Terracing and undercroft areas Controls 35 Section D12.13 provides controls that state: * Lightweight instruction and pier and beam footings should be used in environmentally sensitive areas * Where retaining walls and terracing visible from a public place, preference is given to the use of the sandstone or sandstone like materials * In the provision of outdoor entertaining areas, preference is given to tender its rather than cut/fill, retaining walls and/or terracing. 36 The outcomes in Section D12.13 are: * To achieve the desired future character of the Locality. * To protect and minimise disturbance to natural landforms. * To encourage building designed to respond sensitively to natural topography. The evidence 37 The area of dispute relates to the lower area of open space where a new curved retaining wall is to be constructed to retain fill for the open space area. The retaining wall is to be sandstone faced and have a height near the southern boundary of 0.11 m and a height of 1.2 m near the northern boundary with a maximum height of 2.35 m near the centre of the site. 38 Ms Marshall states that decking is preferable to retaining walls. The control seeks to retain as much of the natural topography and landform as possible and terracing and retaining walls permanently affect slopes which can have detrimental effects on natural water flow over the site, retention of natural vegetation and stability of terraced areas. 39 Mr Boston states the construction of the retaining wall is generally in the location of existing retaining wall. The maximum height of 2.35 m, from the survey plan, appears to be an anomalous measurement given other nearby measurements. In his opinion, the maximum height is more in the order of 1.98 m. The finished height of the retaining wall is substantially lower than the existing elevated deck located on the site and as such will have a significantly less visual impact than currently exists. The retaining wall will not be visible when viewed from any location other than the ocean. In his opinion, the sandstone facing on the retaining wall will be consistent with other properties in the Palm Beach locality and will not appear as inappropriate. Findings 40 Section D12.13 does contemplate retaining walls provided that they are instructed or sandstone or sandstone like material. I would agree with Ms Marshall that in many circumstances, decking is more preferable to fill and a retaining wall however in this case the use of a retaining wall has few disadvantages. The wall is not overly large, is appropriately faced in sandstone material and is only visible from the ocean at a considerable distance from the site. The wall will be largely unnoticeable as an individual element in the range of different building forms, finishes and colours in the general area. While the retaining wall will change the natural topography of the site, it is not such a significant change that it would warrant the replacement of the retaining wall with a deck. 41 It would be appropriate, in my view, to provide additional landscaping in front of the proposed wall to provide additional screening as well as increase the landscaped character of the site between the retaining wall land and the boundary of the site. The landscaping plan should also provide for the replacement of any plant located within this area that may be damaged during the construction of the dwelling and retaining wall. This can be achieved through an amendment to the landscaping condition (see condition C5). 42 I am satisfied that the outcomes for the control are achieved by the proposed retaining wall and consequently, would not be a reason to refuse the development application. Scenic Protection Controls 43 Section D12.14 provides a control that requires development to minimise the impact on existing significant vegetation as well as requirements for screen planting, canopy trees, maintaining the visual integrity of the site and the use of unobtrusive and nine reflective materials and colours. 44 The outcomes in Section D12.14 are: * To achieve the desired future character of the Locality. * To preserve and enhance the visual significance of district and local views of Pittwater's natural topographical features such as, ridges, upper slopes and the waterfront.(En,S). * Maintenance and enhancement of the tree canopy.(En,S) * Colours and materials recede into a well vegetated natural environment.(En,S) * To maintain and enhance the natural environment of Pittwater as the predominant feature of the landscape with built form being a secondary component (En, S) * To preserve and enhance district and local views which reinforce and protect the Pittwater's bushland landscape and urban form to enhance legibility. * To encourage view sharing through complimentary siting of buildings, responsive design and well-positioned landscaping. * To ensure sites are designed in scale with Pittwater's bushland setting and encourages visual integration and connectivity to natural environment. * Development shall minimise any visual impact on the natural environment when viewed from any waterway, road or public reserve. 45 A variation to the provision of screen planting can be considered where the outcomes of the control achieve The evidence 46 Ms Marshall states that the proposed development will protrude forward, rather than step down the slope of the hillside. It will contain vertical elements and not horizontal massing, which is a requirement of the desired future character of the locality. As an example, Ms Marshall states that the dwelling does not provide a full length balcony across the front of the building, which is characteristic of the locality. Once the building protrudes forward, and the adjoining trees are removed, the site will be clearly visible from the ocean, the properties to the north, and adjoining properties. 47 Mr Boston states that the proposed dwelling sits comfortably the low the 8.5 m height control and presents a bulk and scale, which is entirely consistent with the established development in the visual catchment. Amendments have been made to reduce the vertical elements within the building such that a balance of both horizontal and vertical massing will be evident. Findings 48 The site is relatively isolated from locations where it can be viewed by the general public. The most obvious location is from the ocean however because of the steep nature of the site and a cliff near the waterfront, any reasonable view of the site would be from a considerable distance. The site was viewed from a location at Palm Beach, a distance of some 1000 m from the site. While parts of the existing dwelling could be recognised, those parts would be largely unnoticeable amongst the more prominent building forms in the general area. 49 While Ms Marshall was of the view that the dwelling would become more prominent if the trees that currently screen the existing dwelling from Palm Beach are removed; I agree with Mr Boston that the removal of the trees would most likely occur when a dwelling houses is approved on the adjoining property. A new dwelling is likely to perform the same screening of the proposed dwelling as the existing trees when viewed from the Palm Beach area. 50 Ms Marshall's concerns over the absence of horizontal massing of the proposed development are, in my view, without substance. Mr Zuccon provided a detailed response by highlighting the many horizontal elements that make up the building. Mr Boston also explained the ongoing design changes that were made to protect the view lines from the adjoining property and that the inclusion of features such as a full width balcony would likely create further view loss issues. 51 I am satisfied that the outcomes for the control are achieved by the proposed design and consequently there is no reason to refuse the development application on scenic protection grounds. Private open space Controls 52 Section C1.7 provides that a minimum of 80 sq m of private open space per dwelling is to be provided at ground level with no dimension less than 3 m. The controls also provide that "dwellings are to be designed so the private open space is directly accessible from living areas enabling it to function as an extension of internal living areas". 53 Section C1.7 provides the following outcomes: * Dwellings are provided with a private, usable and well-located area of private open space for the use and enjoyment of the occupants. (S) * Private open space is integrated with, and directly accessible from, the living areas of dwellings. (S) * Private open space receives sufficient solar access and privacy. (En, S) The evidence 54 There was agreement between Ms Marshall and Mr Boston that the 80 sq m of private open space was provided however Ms Marshall states that only the private open space of the loggia (39 sq m) should be designated private open space as the lawn area on Level 1 (54 sq m) is located off Bedroom 3 and ancillary rooms and not off the living spaces which are located on Level 3 of the dwelling. 55 This assessment of the private open space is rejected by Mr Boston who states that there is internal stair access to the lawn area on Level 1 that does not require access through Bedroom 3. Mr Boston argues that such an arrangement must be reasonably anticipated for development on steeply sloping sites. He notes that all areas of private open space maintain a minimum 3 m dimension consistent with the requirements of this section Findings 56 I agree with conclusions of Mr Boston on this matter. The quantum of open space required by Section C1.7 is achieved and while it is located in two areas, I accept that the areas will still provide private, usable and well-located areas of private open space for the use and enjoyment of the occupants. Optimally, private open space should be directly accessible from living areas however I am satisfied that the lawn area on Level 1 is sufficiently accessible that it will be used for its designated purpose by the future occupants of the dwelling, particularly given the steep topography of the site. 57 I am satisfied that the outcomes for the control are achieved by the proposed areas of private open space and consequently there is no reason to refuse the development application on the basis of inadequate private open space. Conditions 58 The following conditions were in dispute between the parties and have not been addressed earlier in the judgement: Condition B28 - the council's condition requires all terracing and retaining walls to use sandstone or sandstone like materials. While the applicant accepts that the curved eastern most retaining wall should be constructed of sandstone or sandstone like materials, the condition infers that the proposed walkway within the road reserve should also be constructed of similar material. This is opposed by the applicant. On this condition, I agree with the applicant that the additional requirement is unnecessary and unreasonable. Condition C5 - the council's condition requires the provision of an amended landscape plan to address screening on the southern boundary, the removing of the existing Cocos palms and the provision of additional native trees. The applicant proposes an amended condition that does not require an amended plan but agrees to the removal of the existing Cocos palms. 59 While I accept that the proposed landscaping plan is generally acceptable, I accept that an amended landscaping plan should be provided that indicates the removal of the existing Cocos palms and replacement with an appropriate species, the provision of additional landscaping in front of the proposed retaining wall and a requirement that any existing natural vegetation damaged during the construction of the dwelling should be replaced with appropriate species. Orders 60 The Orders of the Court are: 1. The appeal is upheld. 2. Development Application No. N037/09 for the demolition of an existing dwelling and the construction of a new dwelling at 413 Whale Beach Road, Whale Beach is approved subject to the conditions in Annexure A. 3.
