STATUTORY PLANNING COMMITTEE 17 APRIL 2012 Increased setback distances (to the east walls) Altered external materials/finishes/colours (from highly contemporary to those that would be consistent with the existing dwelling) Increased opportunities for landscaping (in particular along the east, west and south boundaries) 8.4. Heritage assessment of the Murchison Street streetscape In paragraph 14 of Martin v Port Phillip CC, the Tribunal identified that the significance of HO391 is exclusively derived from “the presentation of the houses to the street – noting in particular the cohesion of the dwelling stock with respect to scale, composition, materials and detailing.” These four criteria – scale, composition, materials and detailing – constitute the most crucial heritage considerations to be applied to this particular proposal. Prior to assessing the proposed rear addition at 21 Murchison Street, therefore, it is vital to clarify how these particular heritage considerations manifest themselves within the context of HO391. The scale of dwellings presented to Murchison Street is predominantly comprised by single-storey detached dwellings. Aside from limited examples of modified double-storey and ‘attic conversion’ dwellings at 1, 10, 22 and 29 Murchison Street and a few multistorey medium-density ‘walk-up’ flats at 16A, 18 and 18A Murchison Street, the streetscape is characterised by a relatively uniform low-height, single-storey nature. The visual composition of Murchison Street is predominantly comprised by a regular rhythm of low-scale buildings interspersed by open space areas. These spaces result from the application of relatively consistent building setbacks from side boundaries combined with side driveways extending along one side boundary. Generous front setbacks are also standard. The quality of front landscaping is generally of a high standard, and this serves to compliment the mature trees lining the street. Finally, hipped and gable tile roofs are a consistent feature of the streetscape. The materials and detailing of buildings on Murchison Street are consistent with a design trend known as a ‘Californian Bungalow’ style which was popularly applied to domestic architecture throughout the Inter-War Period (1915-1940). This design aesthetic is identified by prominent front verandahs supported by robust over-sized columns, lowpitched tile roofs creating large, wide gables and the application of timber shingles to external walls as a decorative feature. External finishes include combinations of facebrick, painted render, timber weatherboards and timber shingles punctuated by timberframed windows. Roofs are exclusively clad in tiles. Any proposed addition and/or alteration of the dwelling at 21 Murchison Street, St Kilda East must clearly demonstrate that it would respect and sympathise with the abovementioned heritage qualities. 8.5. Heritage Policy / Heritage Overlay assessment To determine whether the proposed rear addition would achieve appropriate planning outcomes with respect to the Murchison Street streetscape, the proposal must be assessed against Clause 22.04 Heritage Policy. To this effect, the policy guidelines expressed in Clause 22.04-3 for ‘Additions and/or Alterations to Heritage Places’ play the most significant role; however, policy guidelines outlined in ‘Demolition’ and ‘Car Parking’ are also relevant. In response to these guidelines, the following points are noted: The proposed partial demolition of the rear, south wall would not alter the original principal façade or roof of the existing dwelling. The proposed rear addition would be sited below a 10 degree ‘envelope’ projected from the gutter line of the front façade (refer ‘Sightline View (West)’ TP11). Thus, it would comply with Performance Measure 1. The roof ridge height of the proposed rear addition would be constructed 0.5m lower than the roof ridge height of the existing dwelling. As such, the proposed 24
STATUTORY PLANNING COMMITTEE 17 APRIL 2012 rear addition would not impose a higher-scale built form upon the low-scale character of the Murchison Street streetscape. The roof of the proposed rear addition would complement the existing roof and adjoining roofs in terms of its form, pitch and materiality. The external walls of the proposed rear addition would be finished in the same ‘flagstone grey’ render as the external walls of the existing dwelling. Moreover, the fascia, gutters, gates and timber-framed windows would be painted in the same ‘mission brown’ colour applied to corresponding features of the existing dwelling. The roof, rendered walls and timber-framed windows of the proposed rear addition would complement the materials, finishes, textures and colours of the ‘Californian Bungalow’ design style that characterises the Murchison Street streetscape. The overall design of the proposed rear addition would successfully utilise a contextual design approach. The contemporary elements of the proposal – including the bridge/walkway and the continuous row of highlight windows along the west elevation – would differentiate the proposed rear addition from the existing dwelling in an innovative yet sensitive manner. The proposed rear addition would respect the visual composition of Murchison Street. It would maintain established streetscape characteristics including the visual rhythm of built form and open space areas, front setbacks, side setbacks, landscaping and roof forms. The side setbacks of the proposed rear addition from the east and west boundaries would generally meet or exceed those of the existing dwelling and adjoining dwellings. The proposed lower level vehicular garage would be located at the rear portion of the property. The proposed 0.9m high sliding gate at the front boundary would be consistent with the 0.9m high double-hinged gate located at the same position and authorised pursuant to Planning Permit No. 984/2011. Based on the conclusions above, the proposed rear addition would retain and conserve the heritage characteristics of Murchison Street and would respectfully and harmoniously integrate with the surrounding streetscape character. Therefore, it would accord with the objectives and guidelines expressed in Clause 22.04 Heritage Policy. In addition, Martin v Port Phillip CC outlines several streetscape considerations that specifically apply to the relationship between the subject site and Murchison Street. In Paragraph 26, the Tribunal identifies three key elements of the subject site’s physical context that must be considered in relation to any proposed development: 1) the position of the site at the southern terminus of the Murchison Street ‘dogleg’, 2) the topography of the area which affords a prominent, top-down view of the subject dwelling from the ‘dogleg’ and 3) the increased visibility of the rear of the site from the ‘dogleg’ by virtue of the separation provided by the driveway of the adjoining property located at 23 Murchison Street. The view of any rear addition from the ‘dogleg’ to the northeast was considered a particularly crucial vantage point. From this specific location, the only part of the proposed rear addition that would be visible would be its roof, which would be pitched at the same angle and would be clad in the same terracotta tiles as the roof of the existing dwelling. Due to the combination of a proposed 0.86-2m east setback and the strategic positioning of proposed screen plantings along the east boundary (refer ‘Landscape Concept’), the rear addition would not present a prominent built form as viewed along the driveway of the adjoining property 25
