30 The principal contested issue is whether the consent may be modified by the deletion of conditions of consent imposed by the council, subsequent to the deemed refusal or by further modifications of the consent. There was no dispute that Windy Dropdown Pty Limited v Warringah Council [2000] NSWLEC 240, (17 November 2000), the decision of his Honour Talbot J, applies and development consent may be granted retrospectively and subject to conditions. The major unauthorised work is the attic stair roof.
The evidence and findings
Whether the consent should be modified
31 I have concluded that were the applicant to seek consent to the unauthorised works the subject of this appeal under s 97 of the Environmental Planning and Assessment Act 1979 I would grant consent. I consider that were approval sought for the new roof over the attic stair I consider it would be satisfactory when considered afresh.
Rear skillion east/west extension
32 Mr S Atkins at the s 34 Conference, gave evidence on behalf of his father who was overseas at the time, that the twin skylights to the kitchen of No 11 Darley Street, nearest the party wall between Nos 9 and No 11 Darley Street, would be overshadowed by the increased height of the party wall especially around midday in midwinter. This is graphically depicted in Cross-section 3-3 on plan No S96B, dated 5 May 2005, attached to the Class 1 application, prepared by the architect. He was also concerned for the loss of daylight to these skylights.
33 These skylights were oriented with the long side north/south and the northern edge of the skylights was situated around 300mm to 400mm from the southern side of the modified party wall. Each skylight was around 1.2m in length and about 600mm wide. The twin skylights closest to the party wall were supplemented by another pair of skylights further to the south in the roof of the kitchen of No 11 Darley Street.
34 Despite it being difficult to estimate the extent of the unauthorised increase in height of the party wall, the consensus of those present on the s 34 Conference was that the height of the wall might have increased in part by around 770mm. In part, the wall was apparently erected within the easement for support, shown on the survey in Exhibit G. Judging by the view from within the kitchen of No 11 Darley Street and Cross-section 3-3, the angle from the northern edge of the skylights to the top of the new party wall would be around 45-degrees. Some overshadowing would likely occur over the northernmost pair of skylights in midwinter. This was shown by the sun angle at 12midday on the drawing.
35 I have concluded that the overshadowing of the kitchen skylights would not be so severe for most of the year as to warrant refusal of the application. Although there would be likely to be some shade on the northern part of the skylights in midwinter, during the summer months from the equinox there would be expected to be little overshadowing. Also sunlight to the southernmost skylights would be unaffected.
36 Also, even taking into account that the occupants of No 11 Darley Street have been enjoying the benefit of daylight in the kitchen afforded by the skylights for many years, possibly more than 20 years, the modified party wall would not be of such a height as to warrant refusal of the application. I have taken into account that the party wall would probably not penetrate a plane set at an angle of 45-degrees from the northern edge of the skylight nearest the party wall. Thus I am satisfied that the skylights would continue to provide adequate daylight at all times of the year and this would not be a reason to refuse the modification application.
Planning principle - access to daylight
37 Where a person has been enjoying daylight (as distinct from sunlight) from a window or skylight of a dwelling for a considerable period of time, the preservation of this amenity should be given major weight. If a structure is to be erected near the window or skylight, it should not intrude in a significant way within a plane set at 45 degrees to the horizontal at the sill (or, in the case of a skylight, the edge of the skylight nearest the structure), and vertical planes at 45 degrees in plan fanning out from each side of the window.
Attic stair roof
38 During an adjournment of the hearing, the applicant prepared amended drawings of the roof over the new unauthorised stair that links to the attic within the roof of No 9 Darley Street. The design of the roof over the attic stair incorporated a roof pitch to match the pitch of the existing rear section of the main part of the roof and a short lean-to roof also at the same pitch, against the side wall of No 11 Darley Street.
39 Mr E Atkins, the owner of No 11 Darley Street, gave evidence on 13 February 2006 and confirmed the concerns expressed by his son, Mr S Atkins at the s 34 Conference that such a roof would facilitate unauthorised access to the western stair window of No 11 Darley Street nearest the northern boundary of that property.
40 He stated that were the applicant to provide lockable louvred shutters to that window his objection to the proposal would be overcome.
41 I am satisfied that some form of security is required for the rear westward facing stairwell window of the dwelling at No 11 Darley Street, given that a person intent on entering that property would be given greater access by reason of the proximity of the new roof over the stair to the attic of No 9 Darley Street. This roof, as was pointed out by Mr Atkins, leads directly up to the window of concern. One possibility discussed with the parties was the dead bolting in an open position of the stairwell window, so that ventilation of the stair would still be provided but the gap left with the window locked open would not allow a person to enter. Other alternatives discussed were the provision of the shutters as was preferred by Mr Atkins, or a fan of spears on the top of the party wall between Nos 9 and 11 Darley Street near the window in question. Such a fan would afford the same level of security as existed prior to the works being undertaken in No 9 Darley Street. Mr Kondilios undertook to explore with Mr Atkins the possibility of a fan of spears together with dead locks on the window to the stair of No 11 Darley Street.
42 I am satisfied that were the window dead locked open, such that persons would be denied access to the interior of the dwelling at No 11 Darley Street without breaking and entering, security would be maintained and the increased access provided by the new roof over the stair would be addressed. For added security the applicant was agreeable to install the 1.5m fan of spears, if Mr Atkins gave his consent to this.
43 Mr Smith, the heritage architect of the council, maintained his concern for the "…negative bulk, form and location" of the proposed roof over the stairs to the attic, [Note: Exhibit 11].
44 In the supplementary joint conference report of the heritage experts in Exhibit 10, Mr Smith joined with Davies and stated, [Note: Exhibit 10, p 2]
"…the amended roof element shown on the filed drawings is acceptable and is consistent with discussions in court. Mr Smith believes, however, that it is unclear as to whether the element has an eaves gutter or a hip flashing."
45 I am satisfied that with the issue of security of No 11 Darley Street addressed, that the bulk, form and location of the proposed roof over the stair to the attic of No 9 Darley Street would be acceptable when assessed under s 79C of the Environmental Planning and Assessment Act 1979. In coming to this conclusion I have taken into account the submissions of Mr Tomasetti that the proposed attic stair roof would not be visible from public places and would not be visible from the rear of No 11 Darley Street and only marginally visible from No 7 Darley Street. I would not refuse the modification application sought.
Easement for support
46 Mr E Atkins pointed out in Court on 13 February 2006, that the applicant has apparently erected a new section of wall around half a metre high partly on the easement for support shown on the survey plan as Vide Q406706. The length of wall in question is shown in colour on the Exhibit G plan as being around 1m in length in the vicinity of the party wall between Nos 9 and 11 Darley Street. At the s 34 Conference it was noted that similar works had taken place on the party wall between Nos 7 and 9 Darley Street.
47 The applicant agreed to comply with the amended Condition 1(x) and:
…shall submit to Council a Registered Surveyor's certification dated after the service of the proposed Order to verify that the reconstructed party wall and associated building elements of the south-east wing along the southern boundary with 11 Darley Street, Darlinghurst and along the northern boundary with No 7 Darley Street, Darlinghurst, are entirely within the subject premises or, alternately, that all building elements encroaching adjoining property have the benefit of an easement or similar under the Real Property Act, 1900.
48 Mr Atkins had read that condition and I understand would be content if the applicant complied with it. I would not refuse the modification application for this reason were the applicant to comply with this condition.
Internal lining and French door openings
49 The plans in Exhibit J show an internal solid door to the French door openings in the front ground floor rooms of the proposed art gallery. This would enable the internal face of the door in the closed position, to be available for hanging art works and when an exhibition has ended the panel covering the French doors could be removed to reveal the opening.
50 I accept this as a reasonable solution to the difficulty of displaying artworks while retaining the heritage significance of the item.
Inadequate description of the works in the modification application
51 The applicant has filed on 19 January 2006, drawings No 01 and 02 and drawings No 02, 03, 04 and 05 by Cracknell and Lonergan Architects Pty Limited filed 10 February 2006 sufficient to describe the works.
52 These amended architectural drawings in Exhibit G, together with detail of the hipped roof over the stair to the attic in Exhibit H; detail of the door or 'plug' for the front ground floor rooms in Exhibit J; detail of materials of the door to the store in Exhibit K; detail of a removable steel safety balustrade to Room 4 in Exhibit L; and in Exhibit M the Building Code of Australia (BCA) extract with commentary dated 19 January 2006 are sufficient to describe the works.
53 I am satisfied that these drawings meet the requirements of the practice direction with regard to documentation of applications. I would not reject the s96 modification for reason of inadequate description of the works.
54 For the above reasons, the appeal is upheld.
Conditions
55 The conditions are those in Exhibit 1 as amended during the conference.
Orders
56 My orders are:
- The appeal under s 96(6) of the Environmental Planning and Assessment Act 1979 is upheld.
