Hurstbridge

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 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.
Planting non-indigenous tree and plant species.
Visually dominant exotic species.
Planting of any weed species which may spread to adjacent bushland.
(2) Footings / Touching The Ground
To minimise site disturbance and impact onthe landform and vegetation. / The footings of buildings should minimise theimpact of the building on thelandscape setting.
Buildings should be designed to sit above theground amongst the tree canopy or to sit withinthe topography and understorey vegetation. / 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 masonry.
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 sited further forward than 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. / Buildings that penetrate the tree canopy.
Buildings located on ridge tops.
Building height that exceeds the dominantheight within the street.
(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.
Car parking areas, garages or car portsshould not dominate the site when viewedfrom the street. / Carports and garages forward of thedwelling.
Large areas of hard paving in the frontyard.
Significant excavation works.
Long, straight driveways and exposedside fences.
8) Front Boundary Treatment AndFencing
To maintain and enhance the continuous flowof the vegetation and existing landscape. / Provide no front fencing or side fencingvisible from the street.
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.
Avoid constructed gateways and highretaining walls. /
  • Solid front fences and brick retainingwalls.
  • Solid side fencing, particularly in front ofthe dwelling.
  • Paving on front garden 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.

(10) Bushfire / Wildfire Protection
To design and site buildings which minimisethe risk of loss in a bushfire and landscapingwhich minimises the spread and intensity ofbushfires. / Development within the WildfireManagement Overlay is required to conformto prescribed vegetation management, accessand water supply standards or be subject toan approved Fire Risk Management Plan.
Buildings within a designated BushfireProne Area are required to be built inaccordance with Australian Standard 3959.
New properties should have a permanentbuilt-in and easily maintained fire protectionsystem, linked to an independent water andpower supply.
Landscaping and bush retention shouldmaintain an area of defendable space aroundthe dwelling. / Development designs and layouts thatincrease the necessity for vegetationmanagement.
Complicated roof lines and other designdetails where burning embers could lodge.
Sole reliance on reticulated water and/orelectric powered pumps.
Dense dry vegetation and bush litter inclose proximity to the house.
(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.

(12) Street Tree Planting
To continue the indigenous tree canopy as partof a flowing bushland landscape. /
  • Retain and replant native and indigenous canopy trees within the street space in an informal layout.
/
  • 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 bush landscape to the road edge.
  • Continue footpaths with an informal layoutaway from the roadway.
/
  • Straight footpaths.

(14) Roadway Treatments
To retain existing unsealed and sealed roadswith no kerbs. /
  • Onsealed roads with no kerbs use minimalbitumen kerbs if erosion problems occur.

Key Characteristics

  • Rolling to hilly topography.
  • Modified grid street layout or connective bush tracks.
  • Footpaths one side only or not present, roll over kerbs.
  • Predominantly 1970s - 1980s dwellings:
  • generally earth tones, mixed styles and materials.
  • A bushy area with significant native tree canopy.
  • Native gardens continuous with road vegetation, some terraced gardens.
  • Significant native and indigenous tree canopy occurring at a density of one to every 150m2.
  • Some pockets of almost semi-bush with unsealed roads and vacant lots.
  • Few front, some side fences visible from the street.
  • Parts of this precinct are prone to bushfire

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:
