Update from ANSA Homes regarding COVID-19


As our collective focus on sustainability grows, designing and building homes that are smarter and better for the environment is becoming more important than ever.

Since they were introduced by the NSW Government in 2004, Building Sustainability Index (BASIX) requirements have set the standard minimum in sustainable planning measures for all new residential dwellings and renovations in NSW costing more than $50,000.

What is BASIX?

BASIX requirements were introduced to encourage sustainable residential development as part of the NSW Government’s Environmental Planning and Assessment Act. The mandated BASIX certificate does three important things:

  • ensures that NSW has more resilient and sustainable housing options.
  • reduces greenhouse gases and water consumption in new and renovated homes.
  • reduces the cost of living due to using less water and electricity.

Not only is a BASIX certificate part of the development application process in NSW, it is also one of the strongest sustainable planning measures for residential building in Australia.

BASIX’s mission is to reduce our reliance on non-renewable resources to make our homes comfortable. Targets were set at a 40% reduction in water usage and up to 25% reduction in greenhouse gas emissions.

Key BASIX focus areas

There are three areas that BASIX focuses on to meet the minimum requirements for delivering a sustainable home.


When submitting your BASIX application for building your new home, a target of 50% reduction in energy usage needs to be met. If a home has not yet been built, how is this determined? Targets vary but are based on assessing the type of home you are building, and which Energy Target Zone you are building in.


Australia is a country of extremes and water is one of the most valuable resources we have. The benchmark (maximum) set by the Department of Planning & Environment is 90,340 litres of water per person per year (or 247 litres per person per day), which was the average (medium) potable water consumption of a pre-BASIX home.

Depending on the Water Target Zone you are building in, your water reduction target can range  from 40% to 0%. All new home builds with ANSA Homes have a water reduction target of 40%. Read more about BASIX water requirements.

Things to consider around BASIX and water usage include:

  • Landscaping;
  • Fittings and fixtures;
  • Alternative water sources (and their uses); and
  • Pools and outdoor spas.

Targets are based on data provided by state and federal water utilities, as well as data from the Bureau of Meteorology.

Thermal comfort

BASIX thermal comfort requirements define the level of comfort occupants can expect without the use of heating and cooling appliances. The aim is to reduce greenhouse emissions from artificial heating and cooling appliances through efficient building design and the use of appropriate construction materials.

To complete the thermal comfort portion of your BASIX, ANSA uses the Simulation Method  . This is detailed method uses NatHERS accredited software and can simulate a wide range of construction methods and materials.

Beyond BASIX with ANSA Homes

With sustainability becoming more and more of a priority, in 2020 many homebuyers are moving beyond BASIX when thinking about what they want from their new home.

While BASIX sets the mandated minimum in sustainable planning measures, there are many other sustainable initiatives that you can invest in that will make your new home truly green. Your site conditions and the aspect of your new home have the biggest impact on the efficiency of your new home, so getting these two details right is essential.

Have you considered going green for your new home?

When it comes to green homes, there’s green, and then there’s green. Sure, you can put solar panels on your roof and install a recycled water tank, but these steps are merely the start of your sustainable home journey.

Green construction is all about building homes that are healthier and more comfortable to live in while also being better for our planet. It involves using non-toxic, ethical, and sustainable building materials with lower carbon footprints. A key focus is on indoor environmental air quality and the use of renewable resources.

Because a green home is more comfortable, it uses much less energy and has much lower greenhouse gas emissions – making it healthier for our climate and natural environment, as well as for those who live in it.

Beyond BASIX: The frontier of sustainable house design

Since their introduction in 2004, Building Sustainability Index (BASIX) requirements have set the standard minimum in sustainable planning measures for all new residential dwellings and renovations in NSW costing more than $50,000.

But beyond BASIX requirements, there are many further sustainable initiatives that can be built into your new home if you choose a qualified builder with the vision, certification and capability to deliver a true green home.

Europe, and Germany in particular, is considered the global leader in sustainable homes. At ANSA Homes we follow the principles of Energie Einspar Verordnung (EnEV), the low-energy construction code in Germany. Translated into English as German Energy Saving Ordinance, EnEV regulates energy performance for new buildings and building stock as well as energy certification of buildings.

How are green homes built?

To build your green home, we first work with you to determine the ideal temperature range that will make your home most comfortable for you. The house is then designed from the ground up to sit at that stable temperature range year-round without having to rely on energy-consuming heating or cooling.

We do this by designing and building your house using a world class “Intelligent Airtightness System” of up to seven layers in the external walls of your home. This enables your home to be truly airtight without any leakage points that cause the internal temperature to fluctuate.

We also install high performance windows to make your home cooler in summer and warmer in winter. We can also add intelligent thermal mass where needed to stabilise internal room temperatures and further reduce your reliance on energy-consuming heating or cooling.

What are the most sustainable building materials?

reen homes are built using sustainable building materials that have low embodied energy, which ensures that your new green home will consume as little energy as possible for years to come. These products include carbon neutral bricks and wall cladding and natural products such as wool-based bulk insulation and phase change materials manufactured from recycled bio-based materials. ANSA Homes continues to expand its range of sustainable building materials from leading Australian suppliers.

Accuracy matters even more in green home building

The most challenging aspect of building a green home is making sure that your builder has an unwavering focus on quality and a microscopic attention-to-detail. Precise and accurate work is even more important in green home building because even a tiny gap of just 2mm between insulation can decrease thermal performance by up to 50%.

At ANSA Homes, we focus on certainty of process and certainty of design, which enables us to deliver truly accurate work when building your new green home.

Five reasons to build a new green home with ANSA Homes

An ANSA Homes green home design can save you thousands in mortgage repayments through discounted home loan interest rates.

Is a knock down rebuild the right fit for your new home?

If you’re going to go to the trouble of renovating, for both financial and practical reasons a knock down rebuild may be a better option for building your new home just the way you like it.

As an experienced home builder in Sydney, we’ve seen the client success stories that can come from knock down rebuild projects.

And it’s not just about getting the new home you truly want; there’s also a financial benefit. Did you know that the cost per-square-metre of a new build is generally cheaper than the cost per-square-metre of a renovation? This is mainly due to the expense involved in upgrading an existing home and the increased labour required to tie new design features into an old building.

Renovation costs are challenging to predict

All ANSA Homes knock down rebuild jobs come with a fixed price contract, meaning the price you sign off on before work starts is the end price you will pay. Renovation costs on the other hand are more difficult to predict, so builders need to build a contingency into the quote to cover unexpected expenses.

This is partly because every renovation is a bespoke project that is time-consuming and labour intensive. Brand new homes can be built quickly, using proven systems that maximise efficiency and save time. In some cases, repairing major structural damage, sourcing the right kinds of materials, or modernising an old house to bring it up to date in terms of energy efficiency and overall quality has the potential to be very costly and time-consuming.

Knock down rebuild to avoid compromising on your vision

Demolishing your existing house might sound like a big job but it is relatively straightforward with a professional demolition company, who like ANSA Homes can provide a fixed price quote.

Working with a builder that has a tailored approach means the design is packaged into the build. At ANSA Homes our modern designs, including our award-winning house and granny flat design for multi-generation living, are at the forefront of modern housing design. And we can work with you to customise our designs to ensure that you get your new home exactly as you are picturing it in your mind.

Renovations, on the other hand, require you to work around your existing structure, which often involves creative compromise to satisfy the budget. Starting afresh means less compromise and more options around size and style.

Building a new home also gives you the option to kit out your new home with smart technology and green living options – which doesn’t just benefit the environment, but also your bank balance.

Choose a knock down rebuild specialist and avoid the pitfalls of renovation

Still wondering if you should renovate or demolish? Renovations often cost more and take longer than planned because they can uncover unforeseen existing problems. This is particularly true of old houses, which can appear quite sound on the first inspection but may contain hidden problems such as asbestos sheeting or insulation.

Renovations tend to take over your life for the period both leading up to and during the remodelling. There are lots of decisions to be made on an almost daily basis, so if you’ve already got a busy life you may struggle to keep up.

Ultimately you need to decide whether a renovation or a knock down rebuild is the best option for you and your family. So take your time, do the research and enjoy the process.

To provide you with knock down rebuild certainty, we have developed a detailed knock down rebuild guide covering the most critical topics and frequently asked questions.

Special limited offer on knock down rebuilds

At ANSA Homes we know that the cost of building materials are on the rise so we want to help customers get the home they want by locking prices in now. We currently have a special offer for customers to lock in their knock down rebuild price before 30 June 2020. Doing so will protect you from rising building costs due to COVID-19 restrictions.

Trying to decide whether to renovate or demolish? Call us on 1300 757 810 and our knock down rebuild specialists will answer your knock down rebuild questions, or send us an online enquiry.

Five ways to get the most out of your display home visit

With the lifting of COVID-19 restrictions, display homes are once again open and welcoming new home buyers, albeit with adherence to social distancing regulations.

So, now’s the time to get your home-owning plans fully on track and find that perfect home you’ve been dreaming of! While online research is great, there is something special about visiting your nearest display home village and actually walking through the houses and picturing yourself living there.

Get the most out of your next display home visit

Before you jump in the car, here are seven hints and tips from us to you that will help you get the most out of your next display home village visit.

1: Be strategic

It’s going to be a long day, so have a game plan and try to stick to it. Doing so will ensure that you allow time to see everything you want to see and leave knowing that you are one step closer to making your big decision. Have a list of must-see homes to go to first, and a second list of homes to see if time permits. If you plan on visiting HomeWorld Marsden Park, you’ll be able to tour three ANSA Homes’ designs: the Sierra 33 , Brooklyn 32 and Arlo 25.

2: Know what you want

Before going display home hunting, have a firm list of the features you want in your new home. Your list may be general (number of bedrooms and bathrooms, for example), or it may go deep into the finer details.

The more you put on your list, the better it will guide you through your display home visit. Include the type of finishes you want, the type of counter tops, tiles, or bricks that you want. There are no wrong answers here; be guided by what truly matters to you. And don’t be distracted by the glitz and glamour – beautiful interiors are a dime a dozen at a display home village. Instead, focus on the fundamental elements of the home that you will be using daily and look carefully at floorplans and the flow of the house.

3: Document your day

Visiting a display home village is a reconnaissance mission, so make all your time and effort worth your while by documenting your day. You’ll be visiting any number of display homes, and the last thing you want is for them to all blur into one the moment you get in your car and drive home. Capture the experience with detailed notes (including overall impressions of each home you visited) and photos. When you get home, you’ll be glad you did.

4: Know your builders

It’s easy to get wrapped up in the excitement of a large display home village. There can be dozens upon dozens of shiny display homes to peruse and it’s easy to feel like a kid in a candy store and fall in love with all of them.

But choosing your builder is arguably more important than choosing your home. If you like a certain design, research the builder. Do they build as many homes as they can, or the best homes they can? What’s their approach to customer service? What certainties can they give you before, during and after your build? Find a builder that you have a good rapport with and feel you can trust.

5: Not all upgrades are created equal

Display homes are built to impress and are usually fitted with premium upgrades, fixtures and features – many of which may not be included in the base price. So, if you fall head over heels for that bench top, high ceiling, fittings and choice of tiles, make sure you clarify with the salesperson just what’s included in the base home package price. And if you like what you see, ask for the total cost of the house on display, built as is.

6: Come prepared

On the day, be organised and capture as much information and as many details as you can to review once you get home. It goes without saying that you’ll need a notepad, pen, and a smartphone or camera. But it pays to also bring a tape measure, along with dimensions of large existing items (bed, couch, dining table etc) that you’ll be bringing with you into your new home. It would be devastating to find that the home you have fallen in love with just won’t fit your beloved antique cabinet.

7: Have fun and enjoy yourself

Okay, we’ve given you a lot of guidance, but one more thing – have fun no matter what. This is an exciting time for you and your family, so enjoy it. Let your imagination run wild. Your new home is your dream, so dream big, look for certainty and don’t compromise.
