Introduction

Design guidelines and how they work These Design Guidelines relate to all residential lots within SugarGum Estate. This document is a tool to ensure a high quality of design and amenity for all residents and community members. It also seeks to minimise environmental impacts; to respect and enhance the existing natural context; and can offer ways to add to the value of your home.

Some of the guidelines are compulsory, others are suggestions. The compulsory guidelines are presented within this document as “must” and suggestions are represented as “recommendations”.

Your home design must comply with the requirements of the SugarGum Estate Design Guidelines. Home designers must also review and comply with other legally binding documentation, such as:

» City of Swan Town Planning Scheme No. 17

» R-Codes and RMD Codes

» Any relevant Local Planning Policies, codes and standards.

Step 2The Developer will review your application to ensure it complies with the SugarGum Estate Design Guidelines.

» Outcome A: Your application meets all the Design Guidelines’ compulsory requirements. Your application will proceed to Step 3.

» Outcome B: Your application needs to be modified or you need to provide more detail to meet all the compulsory Design Guidelines. The Developer will outline what is required so you can update and resubmit your plans for review.

Step 1Submit the following PDF plans for approval to the Developer by emailing [email protected]:

» Site plan, floor plans and landscaping plans including fencing details (min scale 1:200)

» Elevations depicting materials and fencing details (coloured and min scale 1:200)

Step 3The Developer approves and returns your application to you with a confirmation email. Your builder can now send your approved application and confirmation email (along with all the other information required) to the City of Swan. Please note:

» A building design approved by the Developer does not automatically guarantee building licence by the City of Swan.

» The City of Swan will take the Developer’s approval of a building design into account in the statutory approval process.

» Any changes to a home that do not comply with the Design Guidelines will need to be rectified at the home owner’s expense.

» Development approval is not required for single dwellings that comply with the City of Swan’s Local Planning Policy.

The approval processBefore your new home can be built at SugarGum Estate, you must seek approval from the Department of Communities (the Developer) and the relevant local government authority by following the three steps outlined further.

Street appeal

Street frontage The street frontage of the home plays a role in defining the form and character of the street and must be sited and oriented to directly address the main street and the pedestrian or vehicular approach.

Your home must have a front door and windows that face the street, which will contribute to street activation and passive surveillance, allowing for actual or perceived monitoring of public spaces by people as they go about their daily activities.

The presence of windows and a forward-facing entry will promote opportunities for social interaction and will enhance the street appeal of the development, reducing the likelihood of antisocial behaviour. Your home must further reinforce this by the inclusion of a street facing porch, veranda or entry canopy.

Activation of the street through placement of windows and a main entry point should provide clear direct site lines from the dwelling, while maintaining appropriate privacy for residents.

Corner lots Corner lot homes must be designed to ensure the dwelling addresses both the primary and secondary street. The appearance of both the front and side of the home must be consistent in materiality and design quality. Your home must have at a minimum, one window within a habitable room facing the secondary street, facilitating continued passive surveillance and street activation.

Fencing and letterboxes To help make SugarGum Estate a friendly community with social streets, front boundary fencing is not permitted.

The fencing on your side and rear boundary must be Stratco Good Neighbour Fencing Superdek Profile. It should be 1800mm high and Slate Grey colour. All side and rear boundary gates should match your fence style.

For corner lots, where fencing is provided along the secondary street, one-third of this fencing must be visually permeable, facilitating passive surveillance for windows from habitable rooms and privacy through well designed landscaping.

5

6

This permeable fencing must be Stratco Good Neighbour Fencing Superdek 1150m Colorbond Fencing with 650mm aluminium Slatted Infills, and a maximum height of 1800mm. The remaining two thirds should be Stratco Good Neighbour Fencing Superdek Profile at 1800mm high, Slate Grey colour.

Fences that are provided by the Developer cannot be altered in any way. Nothing can be fixed to or change the nature of permeable fencing, other than landscaping. Temporary screening of permeable side fences such as bamboo, shade clothes and tarps are not permitted. No advertising material or signage is permitted on dwelling fences.

Your letterbox must match the design of your home, referencing materials used for the rest of your home and must be permanent. The materials for the letterbox insert must be either brushed or polished stainless steel, anodised aluminium, bright or satin chrome. Letterbox numbers should be in Century Gothic font between 75mm and 175mm high.

Retaining walls and levels Any modifications to existing retaining walls must be approved by the Developer and must be constructed in the same materials and colours of existing walls.

Driveways Your garage must be positioned to maintain clear sight lines along the street and not to detract from the streetscape or appearance of dwellings; or obstruct views of dwellings from the street and vice versa. Ensure your crossover and driveway are positioned so that they do not conflict with street trees and existing service infrastructure such as light poles and power domes.

Your driveway must be constructed of exposed aggregate insitu concrete, or square profile concrete pavers, laid in stack bond. Diagonal paving arrangements are not permissible. Permissible colour schemes must incorporate grey tones. Refrain from using red, cream, beige or Florentine Limestone colour schemes as these are not permitted. Your crossover and driveway must be completed prior to moving into your new home.

7

Your homeWe want to ensure that SugarGum Estate is a successful residential estate, both in terms of it being a well organised and attractive estate and one that is highly sustainable.

Homes must be designed to utilise passive solar design principles and solar technology, whilst also creating liveable, social streets and public places.

The street facing elevation of your home has an important visual impact on the overall streetscape of the estate. The streetscape is the visual identity of a neighbourhood and plays an important role in facilitating interaction between residents and creating a community. The design of every home should complement each other, working together to present a consolidated design approach which reinforces the design ethos of SugarGum Estate. Well-designed streetscapes encourage connection, understanding and community spirit among residents.

8

Façade treatmentEnsure that the visual impact of your home is complementary to the overall street scape by choosing materials and colour schemes that are compliant with these Design Guidelines.

Your primary street facing elevation must incorporate a mix of a minimum of two materials from the list below, so that houses in the street have their own unique features to make for a visually interesting, but complementary streetscape:

» Rendered brickwork.

» Face brickwork or blockwork.

» Fibre cement sheet modular cladding – paint finish.

» Weatherboard or profiled timber lining.

» Profiled Colorbond steel cladding.

» Stone cladding.

» Feature tiling.

» Timber lined ceiling or eaves.

» Timber look garage door.

» Clear finished timber front door.

» Glazed front door.

This mix is to exclude roof, door and window treatments and each should comprise of no less than 10% of the front façade. Alternative materials to the above list are permitted to be submitted for consideration.

We recommend the construction method of reverse brick veneer, in which the brickwork or blockwork is the inside skin tied to a conventional lightweight stud-framed construction which takes advantage of the material’s thermal mass properties. It can produce high performing buildings with lower than average energy demands for both heating and cooling. We also recommend the use of foil or bulk insulation within cavities to further enhance the thermal resistance of masonry walls.

You should choose materials based on their thermal mass properties. When used appropriately, thermal mass can moderate internal temperatures by averaging day and night extremes, greatly influencing requirements for mechanical heating and cooling methods. Materials with a high thermal mass should be located in areas of the home that are exposed to direct sunlight or radiant heat. We recommend that you choose materials based on their appropriate thermal mass properties while also considering how much they cost to produce. The use of non-toxic, sustainable and/or renewable materials are encouraged. Low or zero-emission volatile organic compound (VOCs) finishes are preferable, as VOCs are considered pollutants that can have adverse effects on the environment and on the health of home occupants.

No advertising material or signage is permitted on dwelling façades.

9

ColourLight colours must be used on external walls and on the roof to reduce the impact of solar heat gain on the dwelling (in particular; walls to the east and west).

Colours incorporated into the street facing façade must incorporate a minimum of two of the colours listed below. Applied paint finishes must match the below list of Colorbond finishes, with Surfmist being the highest recommended option.

Surfmist

Shale Grey

Dune

Bassalt

Windspray

Wallaby

Where approved by the Developer, the use of an approved accent colour may be considered as an alternative to the use of two finishes listed above.

Any face brickwork must be in white, grey or black tones. Cream, Florentine Limestone or beige tones are not permitted.

Front doorThe primary street elevation of your home must include a front door and windows that overlook the street with the front door being framed by a porch, verandah or entry canopy that is separate from your garage. Your front door can be:

» Powder coat aluminium framed glazed door (clear or opaque).

» Clear finish timber.

» Painted timber.

The door is permitted to be a flush panel paint-finished door, external aluminium framed glazed door or a three horizontal-strip glazed feature door.

Garage door, gutters and downpipesYour garage must be located under the main roof of your house and your garage door must be a panel lift style door. Roller doors addressing the street front are not permitted. Gutters, downpipes, capping and all flashing must be made from Colorbond steel or similar, finished in one of the Colorbond (or equivalent) colours listed under the subheading ‘Colour’.

Windows Window style must be modern and contemporary with feature bay windows not being permissible.

Full height glazing down to the slab is recommended on windows at the front of the house facing the street. Windows must have powder coat aluminium frames and be in one of the colours listed under the subheading ‘Colour’.

Natural ventilation can be achieved by two methods, the first being natural cross ventilation, which occurs when dwellings have openings with two different orientations so that breeze can flow through the room or building to flush out hot or stale air. The second method is passive or buoyancy ventilation, which relies on the effect of rising hot air and requires high and low openings so that warm air is flushed from higher openings and cooler air is drawn in through lower openings. Your home must have multiple windows across all habitable rooms to promote these two forms of natural ventilation.

To achieve the best solar orientation for your home, our recommendations are as follows:

» The development is sited and designed to optimise the number of dwellings receiving winter sunlight to private open space and via windows to habitable rooms. Ensure that the main indoor and outdoor living areas are oriented north.

10

» Ensure north facing windows are shaded to reduce unwanted heat gain. Fixed shading above windows should project by approximately 50% of the window height and extend 50% of the window height to either side of the window.

» West or east facing open space may require additional shading from low angle summer sun. Reduce size of windows to the east and west. Utilise fixed or adjustable vertical louvres or blades; deep verandas or pergolas with deciduous vines.

» Consider the use of low-emissivity (Low-E) laminated glazing as this glazing reduces the amount of solar heat gain while still maintaining good levels of visible light transmission.

Permanent roller shutters on windows facing towards primary or secondary street are not permitted. Alternatively, safety window treatments such as crime safe or decorative barriers are encouraged.

11

Summer

Winter

The roof Your roof makes a big impact on the overall style of your home and can also go a long way in making your home more climate-responsive. Where possible, we recommend having at least 40 square metres of roof angled towards the north, to allow for successful placement of solar panels.

For the estate to achieve a consistent design aesthetic within SugarGum Estate, the roof of your home must be designed in accordance with the following criteria to ensure that it is complementary to the surrounding development:

» Hip and gable roofs must have a pitch of 20 degrees.

» Single gable, concealed parapet roofs and skillion roof forms must have a maximum pitch of 20 degrees.

» Eaves must be provided to protect all sides of the dwelling from solar heat gain during summer.

Solar absorption ratings for the roof should be lower than 0.5. This information can be obtained from manufacturers. Metal Roofs should be a sleek, non-reflective profiled steel and therefore Zincalume and tiles are not permissible. Refer to the subheading ‘Colour’ listed earlier in the document for recommended appropriate colour choices. Any colour selected from the recommended list, other than Surfmist will require additional insulation to reduce increased solar heat gain of darker colours during summer.

12

Outdoor living areas Where possible, your outdoor living area must be designed to face north so that it is exposed to solar gain from the north during winter months, while also being protected from wind and rain. Northern facing covered areas will also offer protection from excessive solar heat gain during summer months. Where north facing outdoor living areas are not possible, east facing is also permitted.

Ancillary buildings and building services For SugarGum Estate to maintain a clean uncluttered streetscape with a complementary appearance of all buildings, footpaths, gardens, services and equipment, please ensure that your home adheres to the following guidelines:

» Any outbuildings, sheds, studios or ancillary accommodation must be constructed from a material that complements your home, such as:

• Rendered brickwork.

• Paint-finished cement modular cladding.

• Weatherboard and profiled timber lining.

• Profiled Colorbond steel.

• Face brick or blockwork.

» Other materials may be submitted for consideration but will require approval from the Developer. Any paint finishes must match Colorbond colours that are listed earlier in the document under the subheading ‘Colour’. Accent colours are also acceptable.

» Sheds, storerooms and outbuildings are not permitted to be located at the front of your home addressing the streetscape and must be constructed within the back yard. They must not visually impact on adjacent parks or public open space, or adjacent roadways.

Building servicesIf you are going to opt for the solar power rebate it is important that your builder/architect notes the following:

» No buildings or structure is permitted that will shade the solar panels.

» The solar system inverter needs to be placed in a specific location, either:

• Directly next to your main switchboard at eye level requiring 1 square meter of wall space (but not on a northern wall).

• If the inverter will not fit next to your main switchboard, it may be placed inside your garage in a position where it does not require more than 10 metres of cabling from the main switchboard.

Fibre (NBN) to the home The development will be part of the NBN fibre network so please ensure the house designs and wiring will accommodate this service, and appropriate thought is given to the location of the NBN box within your home.

Sustainable designThe sustainability initiatives applied at SugarGum Estate aim to respond to the needs of today’s and future generations by addressing a range of environmental, social and economic criteria.

SugarGum Estate is seeking EnviroDevelopment certification – a scientifically based assessment scheme that independently reviews development projects and awards certification across the elements of Ecosystems, Waste, Energy, Materials, Water and Community.

The project is aiming for at least 20% or more reduction in greenhouse gas emissions than is required under relevant Federal and State Government regulatory requirements.

Climate-responsive designThe subdivision design of SugarGum Estate orients most lots so that homeowners can benefit from using solar-passive design principles in their home design and take full advantage of opportunities for natural heating and cooling, rather than relying solely on air conditioners, fans and the like.

You should consider the following solar access and natural ventilation recommendations to improve your home’s environmental performance.

Solar access A climate-responsive design makes use of clever positioning in relation to the sun so that your home has solar access during winter for heat gain and is shaded during summer.

Orient the main living area such as the kitchen or family room towards the north so that the thermal mass within your floor slab can be heated by the winter sun. This thermal mass will radiate heat during the evening, reducing the requirement for mechanical heating.

Garages should be positioned to the west side of your home where possible to help insulate your home against solar heat gain from the summer sun. Where it is not possible to locate a garage on the west, locating it on the east is also beneficial.

Planting trees, shrubs and bushes alongside east and west external walls of your home will reduce heat absorption by the dwelling façade and will help to shade your home from the sun. Provide deeper eaves, awnings or verandahs along the west side of your home to further assist with shading from the summer sun.

Positioning laundries, bathrooms and some bedrooms should be to the south side of your home will allow for cooler, more comfortable sleeping wings. These rooms typically do not require much access to sunlight.

15

Natural ventilation Good indoor air-quality is essential for healthy and comfortable living environments, with poor indoor air-quality being a significant contributor to poor respiratory health. In most situations, optimising natural ventilation is the most affordable and effective way to manage indoor air quality. Natural ventilation is the movement of a sufficient volume of fresh air through a dwelling to refresh indoor air.

If your home is designed for good natural ventilation, this will contribute to passive cooling where there is a reduced requirement for mechanical cooling methods such as air-conditioning. Passive cooling is the least expensive means of cooling a home in both financial and environmental terms.

Thoughtfully placed windows or openings to allow for cross ventilation increases airflow to help cool your home naturally. This is particularly important for key living spaces in your home such as the kitchen, dining and family rooms.

Placing smaller windows or openings on the side of your home that gets most of the wind and larger ones on the opposite side, also helps encourage air flow.

Adding roof ventilation, like vented gables, e-vents or wind-activated mechanic ventilators help create air flow.

16

Thermal efficiencyThrough using the right materials and properly insulating your home, you can lower your energy consumption and in turn reduce your power bills. We recommend:

» Making sure there are no draughts in your home by draught-sealing windows and doors to help maintain the temperature inside your home.

» Designing your home so your living and sleeping areas are compartmentalised meaning you can better control the temperature for each area.

» Appropriate use of thermal mass. To be effective, thermal mass must be integrated with sound passive design techniques. This means having appropriate areas of glazing facing appropriate directions with appropriate levels of shading, ventilation, insulation and thermal mass. Use of reverse brick veneer construction for external walls is an example of good use of thermal mass for external walls because the mass is located on the inside and is externally insulated.

» Ensuring that walls include insulation for improved energy and comfort – many builders include this at no additional cost but it is not always standard so be sure to ask. Insulation values should be as per recommended in the building code.

» Dwellings must achieve a minimum 6-star NatHERS rating.

Energy The sun shines in Western Australia for an average 3,000 plus hours a year so using solar as an energy source makes a lot of sense. As well as the environmental benefits, the solar system can help you save on your power bills.

When building your new home at SugarGum Estate you will receive an environmental incentive package. The Developer will provide rebates towards the installation of the following items which are mandatory at the estate:

» Minimum 3kW solar system, optimally located on the northern face of the roof.

» WIFI enabled reticulation controller.

» Smart thermostat system (recommended COP of >3.20 and EER of >3.00).

In addition to good solar passive design, installing efficient appliances, fixtures and fittings will reduce the amount of wasted energy and water within your home and reduce ongoing energy costs. You should consider the following additional recommendations to improve your home’s environmental performance:

» Increase the size of your photovoltaic system.

» Hot water systems should be as close as possible to the area of most use, such as the main bathroom.

» Install a basic energy monitor with the solar power system - a way for residents to see their energy consumption pattern in real time.

» Insulate hot water pipes.

» Electrical appliances should have a minimum 4-star rating.

» Seal downlights and exhaust fans.

» Exterior lighting should be operated via a timed sensor with a manual override switch.

» Internal tap fittings and shower fittings that use <6 litres a minute.

» Dishwasher with an energy consumption of <245kWh per annum.

» Air conditioning systems with COP of >3.20 and EER of >3.00 (see the minimum energy performance standards labelling on the device).

17

Landscaping and gardens (ecosystems)Your front yard adds to the overall appearance of the streetscape. The trees and plants used in the landscaping throughout the estate have been chosen to suit the estate’s unique style. To keep within this style, certain species have been selected for you to use in the landscaping of your home.

Your front garden must include plants of various colours, textures and sizes. Planting edible water-wise plants is also encouraged. All garden beds must be topped with mulch. Artificial turf is not permitted in the front garden and all the front landscaping packages will be lawn free with water-wise plants.

Planting trees, shrubs and bushes alongside your home helps reduce heat absorption and helps shade your home from the sun. Landscaping near lot boundaries is encouraged to achieve additional privacy and shading.

The front landscaping packages are provided by the Developer which includes mandatory lawn free water-wise gardens to reduce the use of non-potable water.

See Appendix 1 for the indicative front landscaping package and recommended plant species list and illustrations. Owners, when ordering plants, should ensure their supplier does not inadvertently introduce weeds of national significance.

Builders shall have in place an erosion and sediment control plan during the dwelling construction phase. The potential for wind or storm water driven erosion on lots spreading on to adjoining properties, public open spaces or bush reserves should be limited through site management actions such as the placement of strategic barrier fences or temporary ground level adjustments.

Waste The estate is targeting low waste production, high recycling rates and ensuring that dwelling design supports recycling initiatives.

There is an overall target for the onsite reuse of demolition, land clearing and civil works materials of 80% minimum by volume. The aim is to contribute to this through the recycling of waste from the dwelling construction phase.

SugarGum Estate is a ‘Smart Waste Zone’. Construction waste is to be managed in accordance with guidance provided by the Master Builders WA Smart Waste Guide. Builders must demonstrate adherence to a documented waste management plan which sets out an approach to ‘avoid, reduce, reuse and recycle’ waste as set out in the guide.

Key principles include:

» The use of skip bins rather than cages.

» Maintenance of waste records.

» Use of contractors who transport waste to a licensed recycling centre.

» Select materials and products which minimise and/or recycle packaging.

» Design dwellings to maximise use of standard sizes of materials wherever possible.

Any waste material removed for disposal shall be through a licensed waste recovery facility.

18

Water The aim is for lot and dwelling design to contribute to a reduced demand on potable water supplies by using water efficient mechanisms and practices, together with the utilisation of alternative water sources such as ground water.

To this end, a bore will be utilised for the water reticulation of street trees and common area ground cover for the first two years as the drought-tolerant street trees are established.

All front landscaping packages have a

mandatory minimum 70% drought-tolerant species (see Appendix 1). All front landscaping packages will include a WIFI reticulation controller which will save a further 15% of water use.

Mandatory use of showerheads that use <7.5 litres of water per minute and taps that use <6 litres of water per minute.

Where installed as part of a house and land package, water efficient appliances such as a dishwasher shall have a water consumption of <14 litres per use and a clothes washing machine with a water consumption of ≤110 litres per use.

19

Safe and accessible livingResidential development should contribute to the wellbeing of the community by providing a sense of safety and security; and a flexible design that is welcoming to a diversity of people, is adaptable to their changing needs, and enables social interaction.

To this end the estate is aiming for dwellings to meet the ‘silver’ performance levels under Livable Housing Australia’s Livable Housing Design Guidelines. This allows your home to be suitable to a wider pool of buyers/occupants and allows owners to age in place. The cost to retrofit a home down the track is cost prohibitive compared to allowing for it upfront.

Key design features include:

» A safe continuous and step-free path of travel from the street entrance and/or parking area to a dwelling entrance that is level.

» At least one, level (step-free) entrance into the dwelling.

» Internal doors and corridors that facilitate comfortable and unimpeded movement between spaces.

» A toilet on the ground (or entry) level that provides easy access.

» A bathroom that contains a hobless shower recess.

» Reinforced walls around the toilet, shower and bath to support the safe installation of grabrails at a later date.

» Stairways designed to reduce the likelihood of injury and also enable future adaptation.

For more details, visit livablehousingaustralia.org.au

Bushfire mitigation Parts of the estate are subject to threat from bushfires. Affected dwellings must be compliant with the Australian Standard 3959-2009 Construction of Buildings in Bushfire-Prone Areas.

Environmentally responsible materials The aim is to responsibly use materials to lower environmental impacts without significantly jeopardising the functionality or liveability of the home.

StructureThe structure of the built form (both above and below ground) shall use at least one of the following:

» Concrete with ≥30% supplementary cementitious materials; and/or

» Structural timber (including formwork timber) which is accredited by the Australian Forestry Standard or Forest Stewardship Council.

Envelope/liningsThe building envelope shall use at least one of the following:

» Plasterboard with ≥10% recycled gypsum; and/or

» Plasterboard which incorporates recycled paper.

ServicesBuilding services shall achieve the following:

» Polyvinyl chloride (PVC) or products containing PVC shall be compliant with the Best Practice Guidelines for PVC in the Built Environment. The Vinyl Council of Australia has a registry of compliant materials which are available from major suppliers.

Emissions from materialsThe aim is to increase the use of those products and finishes which minimise the levels of potentially dangerous emissions such as volatile organic compounds and formaldehyde in buildings for the sake of occupants and tradespeople. The requirements are:

» Only ‘low emission’ paints, sealants and adhesives are used on at least 95% of internal and external surfaces.

» Floor coverings to be free of formaldehyde. and volatile organic compounds.
