Precinct GC2 Guidelines
Diamond Creek Road
Private DomainComponents AndDesign Objectives / Design Responses / Avoid(1) Vegetation Retention AndLandscaping*
To maintain the indigenous vegetation includingcanopy trees and understorey planting andencourage the replanting of indigenous plants(where compatible with other planningrequirements including bush fire safety). / Retain existing high canopy trees whereverpossible.
Retain all remnant indigenous understorey vegetationand replant where appropriate.
Removal of existing trees or developmentadjacent to existing indigenous canopy treesmay require an arboricultural report on theeffects on existing vegetation. / Removal of high canopy trees.
Introducing visually dominant exoticvegetation.
(2) Footings / Touching The Ground
To minimise site disturbance and impact onthe landform and vegetation. / The footings of buildings should minimisethe impact of the building on existing trees. / Extensive excavation for footings adjacentto existing trees.
(3) Building On Sloping Sites*
(a) To minimise site erosion, the detrimentaleffects of excavation and the landscapeimpact of development. / Buildings and other development shouldminimise the impact on the natural slope ofthe site by following the topography of the site.
Retain existing vegetation and plant groundcovers and plants with substantial rootsystems, especially on steeply sloping sites. / Major excavation works to accommodatedwellings or appurtenances.
Large sealed areas (eg. tennis courts) onsteeply sloping sites or where vegetationremoval is required.
(b) To minimise the use and visual intrusion ofretaining walls and batters. / Minimise the height of retaining walls.
Minimise the use of retaining walls withinthe side and front setback areas.
Minimise the area and angle of any batter.
Use material in walls and batters that arecompatible with the bushland setting. / Use of a mixture of materials.
Batters that exceed a slope of 4 to 1.
(4) Position On The Site
To minimise the visibility of buildings fromthe road. / The front and side setbacks should matchthe predominant setback and orientation tothe street of nearby dwellings. / Dwellings or other buildings set further forward of thepredominant setback.
High retaining walls along the sidesetback.
Insufficient side setbacks that inhibitappropriate landscaping.
(5) Height And Building Form
To ensure that buildings and extensions do notdominate the streetscape and the wider landscape setting. / Design new buildings and extensions so as notto exceed the predominant tree canopy height.
Site buildings away from the ridge tops toavoid them being visible on the skyline. (Moveto a more appropriate position on the site).
Buildings near ridge tops should be positionedand designed so as not to protrudeabove the ridgeline, when viewed fromlower areas.
Use simple elevational treatments whichcomplement rather than dominate the bush setting.
In areas with fewer trees, match thedominant height within the street. Wherethere is a dominance of single storeybuildings, the height of the front of thedwelling should match nearby single storeywall heights. / Building heights which are out of scalewith the neighbouring buildings.
Buildings that penetrate the tree canopy.
Buildings that protrude above the ridgeline.
(6) Design Detail And BuildingMaterials
To use materials and building details thatharmonise with the bushland setting. / Use earthy toned finishes or paint colours. / Expanses of highly reflective colour ormaterial.
7) Vehicle Access And Storage
To minimise excavation for car access, impacton the bush setting and on the visibility ofaccess driveway and car storage facilities. / Locate carports and garages behind the lineof the dwelling or in the rear yard unless thiswould require significant excavation.
Access drives should follow the contours ofthe site.
Locate cars in front of the dwelling onlywhere excavation would be required otherwise. / Carports and garages forward of thedwelling.
Large areas of hard paving in the frontyard.
Long, straight driveways and exposed sidefences.
Significant excavation works.
8) Front Boundary Treatment AndFencing
To maintain and enhance the continuous flowof the vegetation and existing landscape. / Provide sufficient space in front for theretention and/or planting of large trees andto retain the bush garden.
Use timber and rock for retaining walls.
Provide no front fencing or side fencingvisible from the street. / Solid front fences and brick retainingwalls.
Solid side fencing, particularly forward ofthe dwelling.
Large areas of hard paving in the frontgarden area.
Absence of trees or large shrubs in thefront garden area.
(9) Sustainability AndEnvironmental Factors
To site and design buildings which maximisethe potential for energy conservation and onsite water collection, where appropriate. / Orientate buildings to the north.
Building forms should maximise the potential for solar heating, solar panelinstallation and rain water harvesting. / Large west facing windows.
Large rainwater collection tanks on smallsites that may be visually intrusive.
Constructed gateways and major retainingwalls.
(11) Construction And SiteManagement
To minimise site disturbance and containbuilding material, construction waste and dust. / Prepare site works plan showing areas ofdisturbance, storage of materials and theproposed construction zone.
Contain all building materials and site waste.
Minimise disturbance to existing vegetation and topsoil with construction, storage ofmaterials and overburden
Protect trees by fencing to the drip line.Work vehicles and materials should not beplaced on nature strips. / Accumulation of large quantities ofbuilding waste on site.
Stockpiling of materials adjacent to or upagainst existing trees.
Excavation for underground servicesthrough remnant bush areas or within thedrip line of mature trees.
Damage to or compaction around allroadside vegetation.
Public Domain ComponentsAnd Design Objectives / Design Responses / Avoid
(12) Street Tree Planting
To continue the indigenous tree canopy as partof a flowing bushland landscape. / Retain and replant Australian native canopytrees within the street space in continuousavenue plantings. / Removal of canopy trees.
New plantings that are not the dominantspecies of the area.
(13) Footpaths / Verges
To retain the bushland landscape to the edge of the roadway. / Retain and enhance the garden landscape tothe road or footpath edge.
Continue paved footpaths on all key routes.
In new areas encourage informal layouts offootpaths to follow contours and respectexisting stands of trees. / Long straight footpaths.
(14) Roadway Treatments
To retain existing unsealed and sealed roadswith no kerbs. / Some traffic calming may be appropriate insome locations.
Key Characteristics
- Rolling to hilly topography.
- Curvilinear street layout with many courts.
- Sealed roads, generally upstand kerbs and footpaths both sides.
- 1980s - 1990s dwellings:
- large site coverage
- often reproduction architectural elements.
- Open feel due to intermittent street trees and immature canopy.
- Reasonably low level gardens with predominantly exotic vegetation.
- Openness created by few front fences.
The Precinct Guidelines contained over the page will be used in the assessment of planning applications in residential areas. A separate document,the Shire of Nillumbik Residential Design Guidelines, provides more detail on appropriate methods to achieve the Precinct Guidelines.Refer to the planning scheme for policies, overlays, and particular provisions which may affect the use and development of land. Check all zoneoverlay and particular provisions in the scheme.For best results, employ an architect or designer familiar with the particular requirements of building design and siting in the Shire of Nillumbik.
Preferred FutureCharacter Statement
Development is sited so that it minimisesdisruption to landform and vegetation.Buildings maintain the pattern oforientations and setbacks of adjoiningproperties and the streetscape. Somevariation occurs where innovative higherdensity housing has and will develop inareas close to activity centres andtransport routes.
Building forms respond to topographic andvegetation contexts. Driveways and carstorage areas occupy the minimumfunctional area, and excavation and otherearthworks are minimal.
Residential development is set among predominantly indigenous trees, althoughthere are some locations where native orexotic trees are present. Hillsides ofresidential development viewed from adistance appear to be lushly vegetated. Intypical streetscapes, substantialindigenous/native trees dominate theskyline and are common in gardens.
Garden planting flows uninterrupted to the edge of the roadway. There is little or nophysical evidence of the boundary between private and public property at thefront of the house, and no solid frontfence. Solid side fences stop level with thefront of the building.
The ‘public’ space between the gardenand the roadway is not delineated as aseparate space, and includes informalnative plantings with some substantialnative trees. Footpaths and verges aregenerally informally aligned, but there aresome formal standard suburban footpathand nature strip layouts. Roadways aremostly sealed with roll over kerb, orsometimes no kerb.
Threats To PreferredFuture Character
Large, bulky dwellings that dominate thelandscape and penetrate the tree canopy.Loss of canopy trees.Removal of indigenous or native vegetation.Formal gardens with exotic plantings that donot blend with roadside vegetation.Introduction of front fences where no frontfences is the dominant pattern.Extensive earth works and excavation foraccess driveways, dwellings or car parking.
Preferred future character:
