Our Green, Smart, Sustainable Home Design & Construct Service
Build a Home That Works for You and the Environment
Building a sustainable home isn't about compromise — it's about building smarter.
At Australian Heritage Homes, we've spent more than 40 years refining how we design and construct custom homes across Melbourne. Sustainable building practices have always been part of our DNA. Our Green, Smart & Sustainable Home Design & Construct Service is the formalised expression of that commitment — a structured approach to delivering homes that are genuinely energy-efficient, healthier to live in, and cheaper to run over their lifetime.
We know that for many families, the decision to build goes beyond four walls. It's about creating a home that works for you financially, environmentally, and day-to-day. Our service lets you choose exactly how far you want to take it — from smarter passive design through to fully integrated solar, water and heating systems — all delivered by our in-house team with three generations of hands-on building experience.
No extra consultants. No inflated pricing. Just expert guidance built into the process from the very first design meeting.

Passive Design: Getting More from the Build Itself
Passive design is about making the most of your home's physical characteristics — orientation, massing, materials, and openings — to reduce the need for mechanical heating and cooling. These measures are low-cost when integrated early, and they pay dividends for the life of the home.
Site and Climate Analysis
Melbourne's suburbs span a range of microclimates. A home in Eltham behaves differently to one in Williamstown. Before we finalise any design, we assess your specific site conditions — prevailing winds, seasonal sun angles, local topography, and any features that may affect shading or airflow. This analysis informs every aspect of how your home is positioned and designed.
Orientation
Getting orientation right is one of the highest-value, zero-cost sustainable decisions you can make. We examine which direction your block faces, where the sun travels throughout the day and across seasons, and how your living spaces can be arranged to take full advantage. North-facing living areas, bedrooms positioned to manage morning sun, and garages used strategically as thermal buffers are all part of this thinking.
Windows and Glazing
Windows are responsible for more heat gain and loss than any other element in your home — but they're also your primary connection to light, views and ventilation. We treat glazing as a system, not an afterthought:
- Larger north-facing openings to maximise winter solar gain
- Smaller or minimal south-facing openings to reduce heat loss
- Cross-ventilation planning so windows work together to cool the home naturally
- High-performance glazing specifications tailored to each orientation
- Draught seals built into our standard construction
External Shading
Correctly sized eaves are one of the most effective shading tools available — they let in the low winter sun and block the high summer sun without any moving parts or ongoing cost. We combine eaves with awnings, pergolas and strategic landscaping to create shading solutions that are both effective and visually integrated into your home's design.
Thermal Mass
Materials like concrete slabs and masonry walls store heat during the day and release it slowly overnight, moderating temperature swings and reducing reliance on heating systems. We specify thermal mass carefully — it needs to be positioned internally to be effective, with appropriate insulation on the outside. When placed poorly, thermal mass can work against you; when placed well, it's one of the most powerful passive tools available.
Passive Heating and Cooling
A well-oriented and well-designed home can dramatically reduce — and in some seasons eliminate — the need for mechanical climate control. We design homes where winter sun enters deep into living areas, lands on thermal mass, and is retained overnight. Summer shading and cross-ventilation then allow the home to cool naturally. We plan this at the floor plan stage, factoring in internal zoning, ceiling heights, and operable window placement.
Insulation
Insulation is the blanket that keeps your home's temperature stable. Without it, up to two-thirds of a home's heat energy can escape through walls, ceilings, floors and the slab edge. We specify insulation on a room-by-room, element-by-element basis — selecting bulk, reflective or composite products based on what each location requires. Our construction practices consistently deliver excellent results on blower door pressure testing, which means the insulation we specify actually performs as intended.
Draught Sealing
Air leakage can account for up to 25% of winter heat loss in a home — and most of it goes completely unnoticed. Our construction standards go well beyond the minimum required. We seal penetrations, install quality door and window hardware, and build airtightness into our process rather than relying on a final patch-up. This leakage control is fundamental to the real-world performance of any sustainable home.
Landscaping
Thoughtfully placed trees, shrubs and gardens contribute meaningfully to your home's passive performance. Deciduous trees on the northern and western sides provide shade in summer and allow sun through in winter. Native plantings reduce irrigation needs and support local biodiversity. We incorporate landscaping considerations into the design phase so the site and the structure work together as a single system.
Active Measures: Choosing What Works for You
Beyond passive design, a range of active technologies can further reduce your home's running costs and carbon footprint. We help you assess which measures offer genuine payback for your situation — taking into account your household's energy usage patterns, any applicable government rebates, and how each measure will be integrated into your home's design.
Responsible Construction Practices
Sustainable building starts on the job site. We separate and sort waste at every AHH site:
- Steel — recycled or reused
- Timber off-cuts — reused or recycled where viable
- Cardboard and paper — recycled
- Concrete, brick and tiles — recycled
- Excavated soil and rock — reused on-site for landscaping where possible
- All structural timber — plantation-grown or recycled
- Wastewater — retained and disposed of responsibly
We also prioritise Australian-made and locally sourced materials wherever possible, supporting local supply chains and reducing transport emissions.
Low-Allergy Construction
For families with allergies, asthma, or chemical sensitivities, low-allergy construction techniques make a real difference to day-to-day comfort. We can incorporate:
- Low-VOC paint systems on all internal walls, ceilings and trims
- Low-allergy floor finishes
- Low-toxicity adhesives throughout
- Gentle heating and cooling systems that minimise dust and allergen circulation
Solar Power
A rooftop solar PV system allows you to generate your own electricity and significantly reduce energy bills over the life of your home. We integrate solar from the design stage — roof pitch, orientation, and structural loading are all factored in so your system performs at its best. We're also happy to advise you on the Victorian Government's solar rebate program, which can meaningfully offset installation costs for eligible households.
Solar-Boosted Hot Water
Hot water heating typically accounts for around 25% of a household's energy bills. A solar hot water system — or heat pump — dramatically reduces this cost, and in some configurations can double as a supplementary in-slab heating source.
Heating and Cooling Systems
A well-designed passive home shouldn't need much mechanical climate control — but when it does, we specify systems that work efficiently:
- Hydronic in-slab heating — comfortable, even, draught-free warmth using hot water circulated through the slab
- 5-star, zoned natural gas ducted heating — efficient whole-home heating with individual zone control
- Reversible ceiling fans — low-cost cooling and winter heat destratification in living areas and bedrooms
- Solar-integrated cooling — where solar capacity allows, cooling loads can be offset significantly
Energy-Saving Technologies
We build energy efficiency into every Green, Smart & Sustainable project from the start:
- LED lighting throughout — specified as standard across the home
- "Kill switch" panel near the exit door — cut power to nominated non-essential circuits when you leave, eliminating standby drain
- 5- and 6-star rated appliances — selectable from our network of green suppliers and incorporated directly into the build
Water Saving
Water is increasingly precious across Melbourne. We can incorporate:
- Rainwater tanks — sized to supply all toilets and outdoor irrigation, with options to upsize if this is a priority
- Water-efficient fixtures — WELS-rated taps, showerheads and toilets that reduce consumption without sacrificing performance
- Water-wise landscaping — designed around local rainfall patterns and native species that thrive without regular irrigation
You can choose any of the following measures to further elevate the sustainable performance of your home, reduce your energy bills and further reduce your carbon footprint.
Reduce, reuse, recycle
- We sort all debris on any job site:
- Steel: recycled or reused
- Timber: off-cuts reused or recycled
- Cardboard and paper: recycled
- Concrete, Brick, Tile: recycled
- Excavated soil & rock: reused on site for landscaping
- All timber: plantation grown or recycled
- Waste water: retaining and disposed of
We source locally
- Our company sources materials from local suppliers where possible
- Steel: recycled or re-used
- Recycled bricks (if selected by our customers)
Low-allergy building
Low-allergy building techniques can be incorporated into any build where this is a priority to our clients. This means:
- Low VOC painting system to all internal walls, ceiling & trims
- Low allergy floor finishes
- Gentle heating and cooling systems
- Low toxicity adhesives
How We Work With You
Our Green, Smart & Sustainable Home Design & Construct Service isn't a fixed package — it's a conversation. We begin by understanding your priorities, your budget, and what matters most to you and your family. From there, we map out which passive and active measures will deliver the greatest return for your specific situation.
We target a minimum 7-star NatHERS energy rating across all our sustainable builds. Higher ratings are achievable with the right combination of measures — our design consultants will show you exactly what's possible.
With energy bills continuing to rise across Melbourne, the lifetime savings from a well-designed sustainable home are significant. But your comfort, your design vision, and your budget always come first. We see the energy savings as the bonus — the icing on the cake of a home you'll love living in for decades.
