v
Woollahra Council

Judgment

1 This is an appeal under s 97 of the Environmental Planning and Assessment Act 1979, against the decision of the (the council) to refuse a development application to alter and add to the rear of an existing single-storey weatherboard cottage at Lot B DP 436837, being No 1 Paddington Lane, Paddington, NSW.

2 The on-site hearing was held on 10 February 2004 and residents were present.

3 I have concluded that the proposal would be a well-mannered response to its context within the Paddington Heritage Conservation Area, would retain the form of the existing single-storey building when viewed from Paddington Lane, and should be approved with conditions.


The land
4 The land is situated on the northeastern side of Paddington Lane about 50m south of Cascade Street. It has a frontage of 6.095m to Paddington Lane, a depth of between 11.105m on the eastern boundary and 12.685m on the western boundary, a rear boundary with several segments of 3.465m, 1.25m and 1.42m, giving an area of 69.6m2. The land falls slightly from Paddington Lane to the rear.

5 Erected on the land is a single-storey weatherboard cottage with a gabled corrugated iron roof with the ridge parallel to the lane. To the rear of the cottage is a single-storey laundry annex with a flat roof. In the northern corner of the land is a small courtyard.

6 Abutting on the northwest is No 19 Windsor Street, a two-storey terrace, and to the southeast is a single-storey garage at the rear of No 23 Windsor Street. To the north is the rear courtyard of No 21 Windsor Street.


Relevant planning controls

Woollahra Local Environmental Plan 1995, (WLEP)
7 The land is zoned Residential 2(a) under the WLEP, and the proposal is permissible with consent. The land is within the Paddington Heritage Conservation Area.

8 Under the provisions of the WLEP the maximum height limit is 9.5m.

9 Other special clauses and development standards apply under the WLEP including: Clause 18 Excavation; Clause 25 Water, wastewater and stormwater and Clauses 26-33 Heritage and conservation area provisions.


Paddington Development Control Plan, (PDCP)
10 The PDCP applies to the land. Relevant are:


• Part 5.1.3 of the PDCP, Street frontage;
• Part 5.1.3 of the PDCP, Rear elevations and yards;
• Part 5.1.4 of the PDCP, Roofs;
• Part 5.1.7 of the PDCP, Building height bulk and scale;
• Part 5.1.8 of the PDCP, Visual privacy; and
• Part 5.3.1 of the PDCP, Single-storey buildings.

The proposal and its history
11 On 19 August 2002, the council refused a development application No 277/ 2002 to add a first floor above the existing cottage on the land.

12 Development application No 373/2003/1 was lodged with the respondent council on 12 May 2003, to alter and add to the rear of an existing weatherboard cottage on the land.

13 The changes to the 1870s cottage would provide two bedrooms, one and half bathrooms and an existing small courtyard.

14 The 6m-proposal would comply with the 9.5m maximum height limit set under the WLEP and the council officers considered this height appropriate.


Notification
15 The application was notified to nearby owners and occupants and four objections received from: Mr and Mrs P & A Andrews, of No 23 Windsor Street, Paddington, 2021; Ms L Mellos, of No 1 Gibson Street, Bronte, 2024 (owner of No 50 Paddington Street, Paddington); Mr and Mrs L N and O J Smith, No 19 Windsor Street, Paddington, 2021; and Mr Stuart and Mrs Suzanne Clough, No 21 Windsor Street, Paddington, 2021.

16 The objections raised the following issues:


• Size and bulk of the proposed addition is excessive, the eastern wall will adversely impact upon the amenity of the adjacent property;
• Proposed overshadowing as a result of the development is not acceptable;
• The existing cottage is an anomaly in a space where it would be usual for garaging requirements to be located. The proposed development will result in a larger structure that is usual for this location with minimal space separating it from the laneway;
• Concerned that in the future there will be proposals to increase the second storey area of the proposed addition;
• The approval of an additional floor in an area originally intended for vehicles will set a dangerous precedent;
• The two-storey structure without a frontage will unduly impact upon the nature of Paddington Lane;
• There is no geotechnical report;
• The proposed excavation may undermine the footings for the wall built up to the eastern boundary on No 19 Windsor Street, Paddington;
• The plans do not indicate how the new roof is to be flashed on the eastern side; it should not encroach into the adjoining property. The proposed courtyard will be at a much lower ground level than surrounding properties, there is no indication as to how stormwater will be removed from this area;
• The proposed first floor addition will have a detrimental impact on the acoustic privacy off adjacent properties.
• The proposed development will have an adverse visual privacy impact on the first floor bedroom of No 21 Windsor Street;
• The courtyard is proposed to be grassed. The courtyard does not receive sufficient sunlight for grass to grow;
• The proposed rear wall between Nos 21 Windsor Street and No 1 Paddington Lane is proposed to be demolished, the owners of No 21 Windsor Street seek further clarification on this issue;
• The proposed level of the AG lines next to the footings is 750mm below the existing ground level. No provision is shown of how to remove the water collected on the Stormwater Concept Plan. The termination point of the gas flue pipe is within 1 metre of a wall vent in the wall built up the eastern boundary and on No 19 Windsor Street, gas may enter this vent;
• The proposed development does not comply with Clause 2(2)(g) of the Woollahra LEP;
• The proposed development does not comply with Clause 8(5) of the Woollahra LEP;
• The proposed development does not comply with Part 5.1.3 of the Paddington DCP, Street frontage;
• The proposal does not comply with Part 5.1.3 of the Paddington DCP, Rear Elevations and Yards;
• The proposed development does not comply with Part 5.1.4 of the Paddington DCP, Roofs;
• The proposed development does not comply with Part 5.1.7 of the Paddington DCP, Building Height Bulk and Scale;
• The proposed development does not comply with Part 5.1.8 of the Paddington DCP, Visual Privacy;
• The proposed development does not comply with Part 5.3.1 of the Paddington DCP, Single Storey Buildings; and
• The proposal would have a detrimental impact on the amenity of the neighbouring residential properties and the character of the Heritage Conservation Area and is not in the public interest.


17 The council’s planning officers who assessed these objections, considered the proposal would not have a detrimental impact on the amenity of neighbouring residential properties or on the character of the Paddington Heritage Conservation Area, and recommended approval of the application. They considered the application would not be other than in the public interest.

18 As the proposal is within the Paddington Heritage Conservation Area the council's Heritage Officer, Mr I Kirk, made an assessment and concluded:


Description of Buildings
The existing building is a 1-storey Victorian weatherboard cottage that has been altered but the original form is intact.

Significance of Property to the Conservation Area
The existing building dates from the key period of significance for the conservation area and is contributory in the streetscape.

Assessment of Heritage Impact
The proposal was the subject of a pre DA meeting. The proposal will have little impact on the significance of the conservation area as it will not be visibly prominent and the new work is confined to the rear, which still allows the original and significant building form to still be interpreted.

Recommendation
APPROVAL subject to the following conditions of consent:
1. The front of the building including the timber cladding, doors and windows shall be retained and conserved.
2. The new roofing shall be corrugated in profile and grey in colour.
3. The proposed obscure white glass to the front windows be deleted.


19 The council officers recommended that Conditions No 2, 3 and 4 be applied to any consent.

20 The council officers had recommended approval of the application as they considered it:

1. Complies with the relevant planning standards contained within the Woollahra LEP;
2. Accords with the objectives of the Paddington DCP;
3. Will not adversely impact on the character of the Heritage Conservation Area; and
4. Will not have an adverse impact on the amenity of the neighbouring residential properties.
The council’s decision
21 Despite the recommendation for approval by its officers, the council by notice dated 4 September 2003, refused the application for the following reasons:

1. The development would have an adverse impact on the amenity of the neighbouring properties (Nos 21 and 23 Windsor Street) with respect to aural and visual privacy, solar access and ventilation.
2. The development is considered an overdevelopment of the site.
3. The proposed excavation is considered to be contrary [to] clause 18 of the Woollahra Local Environmental Plan 1995.
4. The siting of the development in relation to the property boundaries is considered to contravene the Paddington Development Control Plan, Part 5.1.5.
5. The proposal is considered to contravene the provisions of the Paddington Development Control Plan relating to single-storey buildings, Part 5.3.1.


The hearing
22 The appeal was filed on 2 October 2003.

23 At the hearing the court heard evidence on behalf of the respondent council from:

• Mr P Andrews, resident of No 23 Windsor Street, Paddington, [Note: Exhibit 4 p 66];
• Ms S G Clough, resident of No 21 Windsor Street, Paddington, [Note: Exhibit 4 p 70]:
• Mr L N Smith, resident of No 19 Windsor Street, Paddington, [Note: Exhibit 4 p 67-8
• Mr A J Rowan, town planner.
24 On behalf of the applicant Mr Garcia, architect gave evidence.


The issues
25 On 4 November 2003 the council filed a statement of issues.


1. Whether the proposed development would be acceptable having regard to Clauses 2(2)(g)(ii) and 8(5) of the Woollahra Local Environment Plan 1995 ("the LEP"), in that it would have an adverse impact on the heritage significance of the heritage conservation area in which 1 Paddington Lane, Paddington is located.
2. Whether the proposed development is acceptable having regard to its non-compliance with Clause 18 of the LEP, in that the amount of excavation is excessive in the context of the close proximity of the neighbouring residential structures.
3. Whether the proposed development is acceptable having regard to its non-compliance with Part 5.1.5 of the Paddington Development Control Plan ("the [P]DCP"), in that it would be an overdevelopment of the site. In particular: 5.1.5 Site coverage, setbacks and levels - Objectives 02, 03 and 04, and Guidelines G2, G3 and G5.
4. Whether the proposed development is acceptable having regard to its non-compliance with Part 5.1.7 of the [P]DCP, in that compliance with Part 5.1.7 of the [P]DCP, in that it would be excessively high and bulky in the historic context of the neighbouring buildings and impact on the solar access to the private open space areas of 23 Windsor Street. In particular: 5.1.7 Building height, Bulk and scale - Objective 05, and Guidelines G3 and G4.
5. Whether the proposed development is acceptable having regard to its non-compliance with Part 5.1.8 of the [P]DCP, in that it would have an adverse impact on the aural and visual privacy of the habitable room windows and private open space areas at 21 and 23 Windsor Street. In particular: 5.1.8 Acoustic and Visual Privacy Objectives 01 and 02, and Guidelines G5 and G6.
6. Whether the proposed development is acceptable having regard to its non-compliance with Part 5.3.1 of the [P]DCP, in that it would adversely impact on the integrity and setting of the existing single storey building. In particular: 5.3.1 Single storey buildings - Objective 03 and Guideline G4.
7. Whether the proposed development is in the public interest.
8. Issues raised by objectors.

26 The following emerged as the salient issues:

• Paddington Heritage Conservation Area implications;
• Proposed bulk and scale of the development;
• Potential for adverse overshadowing as a result of the proposed development and the potentially adverse visual and acoustic privacy impacts upon the adjacent properties; and
• Provision of private open space and soft landscaping.

The evidence and findings

Paddington Heritage Conservation Area implications
27 Clause 8(5) of the WLEP requires that:


Council shall not grant consent to the carrying out of development on land to which this plan applies unless the Council is of the opinion that the carrying out of the development is consistent with such objectives of this plan and of the zone within which the development is proposed to be carried out as apply to that development.

28 The provisions of Clause 2(2)(g)(ii) of the WLEP states;

2(g)(ii) The objectives of the plan are:
...in relation to heritage conservation:
...to ensure that new development is undertaken in a manner that is sympathetic to and does not detract from the heritage significance of ... heritage conservation areas.


29 Mr Rowan, a heritage consultant, sought to retain a degree of integrity in the existing timber cottage and suggested in the event the Court were minded to grant consent, “…the applicant provide a ‘detailed methodology’ statement, prepared by a consultant qualified in heritage conservation and with experience in construction management” to explain how the building would be retained. Proposed Condition 4 is accepted by the applicant, and would address these concerns.

30 Mr Smith for the applicant stated:


8.4 It is relevant to note that the subject site is not listed as a heritage item under the provisions of the WLEP, but is located in a Conservation Area. Accordingly, the assessment criteria is whether the proposal is likely to detract from the heritage significance of the area, and therefore be inconsistent with the relevant objective, thus triggering Clause 8(5).
8.5 In determining whether or not a development is "inconsistent" with LEP objectives, it is not necessary for the applicant to show that the development promotes or is ancillary to the objectives, but rather that the proposal will not be anti-pathetic to those objectives.
8.6 Overall, the application demonstrates a well-mannered and considered response to the heritage context of the neighbourhood and the siting and orientation of adjoining development by keeping the height, bulk and scale of the proposal as low as possible, locating the maximum height of the addition well back from the street front alignment (ie Paddington Lane) behind the existing single-storey cottage and maintaining the existing pattern and footprint of development already on the subject site. In this regard, the proposal is to be constructed boundary to boundary west to east across the front portion of the site (as exists currently), with the rear extension constructed on the eastern (side) boundary and part northern (rear) boundary (also as exists currently). A courtyard area is maintained at the north western (rear) corner of the site in the same location as the current private outdoor space.
8.7 Accordingly, it is concluded that the proposal is not anti-pathetic to the objective', to not detract from the heritage significance of the conservation area.

31 From the viewpoint of persons standing in Paddington Lane the proposal would be low in scale and the new roof of the rear extension would not be visible. The applicant is willing to maintain the existing clear glass windows either side of the entrance door on Paddington Lane and to maintain the form and appearance of the existing single-storey weatherboard building. The plans in Exhibit A were amended to reflect this and I accept the evidence of Mr Smith that the proposal would not detract from the heritage significance of the conservation area when viewed from Paddington Lane.

32 From Windsor Street the proposed new roof and louvre screen would be visible at a distance of some 23m from the southern footpath and would be seen through a break between Nos 19 and 21 Windsor Street. In my opinion the impact on the streetscape of Windsor Street or on the conservation area from this viewpoint would be so slight as to not warrant refusal of the application. The photographs supplied by Mr Andrews confirms the impact, which would result in the foliage of trees to the south being lost to view.

33 Mr Rowan gave evidence that the proposal would reduce the open area between the rear of the Windsor Street properties and their outbuildings such as rear lane garages. This open area stretches the length of a street block and was estimated to be of the order of 200m. The open area is blocked at the western end by the sidewall of No 19 Windsor Street which is a terraced house that is out of alignment with others in Windsor Street. The proposal would partially block the open area some 6m short of the sidewall of the neighbouring terraced house (No 19). Mr Rowan considered some blocking of the open area acceptable. He found acceptable a rear extension on the land, built as a lean-to structure, against the sidewall of No 19 Windsor Street. The proposal would partially block that open area around 3.5m short of the extension that Mr Rowan would condone. In the circumstances, I would not refuse the application for reason of it partially blocking the rear area of the Windsor Street properties and that it would detract from the heritage significance of the conservation area when viewed from the rear of those Windsor Street properties and from Paddington Lane.


Proposed bulk and scale of the development
34 The proposal when viewed from the rear of No 21 Windsor Street and the courtyard of No 23 Windsor Street would be of a similar bulk and scale to the rear extension of Nos 19 and 23 Windsor Street. This was confirmed on site by means of a calibrated telescopic pole and by reference to the survey plan in relation to the levels of No 19 Windsor Street. The pole may be seen in the photographs taken by Mr Andrew some taken in the rear courtyard of No 21 Windsor Street. The enclosing effect when viewed from No 23 Windsor Street would be ameliorated, in part, by the stepped in plan party wall between the land and No 21 Windsor Street. Some sky would be lost from viewpoints within the rear yard of No 21 Windsor Street and from the rear courtyard of No 23 Windsor Street; however, the proposed rear extension would largely fall within the profile of the sidewall of No 19 Windsor Street. I would not refuse the application for reason of its bulk and scale.

35 Issue 6 was whether the proposed development would be acceptable having regard to its non-compliance with Part 5.3.1 of the PDCP, in that it would adversely impact on the integrity and setting of the existing single-storey building.

36 Clause 5.3.1 of the PDCP relates to single-storey buildings. Objective O3 and Guideline/control G4 is:


O3 To conserve the settings of single storey buildings:
G4 Single storey additions of an appropriate form and scale are permitted to the rear of existing buildings.


37 Under the Environmental Planning and Assessment Act 1979 s 79C the Court is required to give “real, genuine and proper” , consideration to the provisions of the development control plan and these provisions should be a focal point of the planning consideration. Zhang v Canterbury (2001) 115 LGERA 373 per Spigelman CJ.

38 The proposed rear extension would not be visible within the context of Paddington Lane above the ridge of the existing cottage. From the rear, in the courtyards of Nos 21 and 23 Windsor Street and from the footpath in Windsor Street, the proposal would be visible, however, the bulk and scale would be no greater than found in those neighbouring properties.

39 The proposal is not of a design form anticipated in the design suggestions under Section 5.3.1 of the PDCP, [Note Exhibit 4 p 94], where a pavilion structure "... involves constructing a separate block element which repeats the general form of the original house."

40 However, despite such pavilions being restricted in most cases to single-storey, a two-storey pavilion would be acceptable "...when it is not visible from the street and when it has negligible impact on the amenity of neighbouring properties in terms of loss of sun, light and ventilation, and when it does not adversely affect the setting of the building or dominate the existing building in terms of bulk, height and scale."

41 In Section 5.3 of the PDCP [Note: Exhibit 4 Fig 4 p 95] an extension to a cottage is shown as 'intrusive development’ if it does not respect the existing scale and form.

42 Mr Rowan’s evidence was that [Note: Exhibit 5 p 17]:

The extension will dominate the rear elevation and presentation of the cottage within its site, and diminish any understanding of its original context from surrounding properties.

43 The proposal would conserve the setting of single-storey buildings when viewed from Paddington Lane and would be a rear two-storey addition of an appropriate form and scale and different to that shown in Figure 4 as it would not be visible above the roof of the existing. In this regard I prefer the evidence of Mr Smith that the proposal makes a "well-mannered response to that context".


Potential for adverse overshadowing as a result of the proposed development and the potentially adverse visual and acoustic privacy impacts upon the adjacent properties
44 There would be some overshadowing of the courtyard of No 23 Windsor Street in the afternoon from the equinox to midsummer, as shown in Exhibit A Drawing No DA03. As was confirmed by the shadow diagrams there would no additional overshadowing in the winter months of No 23 Windsor Street courtyard. The orientation is such that this impact during this [summer] period would be slight. I am satisfied that the level of overshadowing would not be a reason to refuse the application.

45 The proposed fixed and canted louvres covering the northern windows would ameliorate visual privacy impacts on No 21 Windsor Street. There are no other visual privacy impacts identified.

46 Acoustic privacy would be limited by the fact that the upper floor would be used as a sleeping area. The ground level courtyard would be excavated slightly and together with new masonry walls noise from the lower habitable level might be ameliorated. The same or slightly lower noise levels as presently exist might be expected from the normal domestic use of the ground floor of the proposal.


Provision of private open space and soft landscaping
47 The provision of private open space and soft landscaping on the land would be less than presently provided. Mr Rowan’s concern in this regard seemed to relate to the lack of sunlight to the courtyard in midwinter due to the height of the enclosing wall, the level of the proposed courtyard and the shading effect of other buildings nearby. However, the proposed open space would be on the northern side of the proposed extensions and around midday in midwinter the rooms that open onto the courtyard would receive sunlight despite the ground of the courtyard being mostly in shade at that time.

48 North facing living rooms are desirable and overall, I consider the limited solar access would not be a reason to refuse the application.

49 For the above reasons, the appeal is upheld.


Conditions
50 The conditions are those in Exhibit 6 as amended during the hearing.

51 My orders are:


1. The appeal under s 97 of the Environmental Planning and Assessment Act 1979 is upheld.
