Choosing the Right Natural House for you

Step 1: Work out what you can afford

This is a critical step. Find out what is in your maximum budget. Get your finance and do all the paperwork for the first home owners grant.

Does this include: kitchen appliances, site costs (water tanks, septic, gas, power, phone), landscaping, built in wardrobe finishes, driveway, painting, paint, outdoor fresco area and furniture, window coverings, floors.  Mostly these are not covered so be aware of allowing for them at some stage. Now you know what other costs you can expect to pay. Do your budget. There are a lot of costs which most suppliers won't tell you about as they don't organise them. DO YOUR FIGURES!

Step 2: What do you want your home to be and do for you?

1.                  To Be: What kind of environmental home do you want?

Design: Is the most important part of building the best environmental home you can. To be truly a natural home, it needs to be solar passively designed (take into account thermal mass and insulation walls & floors etc). It also needs to be specially designed for the wall material. For instance, building a straw home means you need to have your windows and doors in the right place for bale sizes. The walls also have to be engineered so if you’re using standard plans (with pre-engineered done already) it will cost a lot less than having to design a home from the beginning.

Materials: Do you just want some environmental products which are better than others on the market? There are many homes which claim to be eco-homes, eco kit homes, eco this and eco that, but use plantation materials rather than actually being environmental.

Do your research. It’s like food, the more processed a product is, the less natural it will be.

2.                  To do: What do you want your home to do for you?

Work out what you will need in your home in terms of bedrooms, living areas and storage as well as garage and entertaining areas.

True environmental homes are modest in size and not just a huge mansion for two, made from the earth for example. Yet a home needs to be comfortable as well as practical.  Open plan living is a great way to live, we’ll just help you be able to manage the temperature o n those cold winter nights in such a big open space. Stairs are another sticking point with keeping heat in. Can you do a renovation rather than build a new home? Will this save money or just be a headache?

Step 3: Choose your design

There are so many builders out there doing different things. Find one which you believe has experience, the products and the skills to build your environmental home. Have they been in the natural building industry for longer than 10 years so they’ve been able to get a product which consistently works? Are they mavericks or do they use techniques which are proven to work? Are they a Master Builder which means they’re a qualified Builder and a member of the Master Builders Association of NSW? They’re covered by insurances, adhere to the Building Code of Australia and ensure your home is under warranty. There are only a handful of licensed builders in the environmental home industry in Australia, even less who build sustainable project homes.

If you prefer to owner build and buy a kit, what is included in the kit? Some prices quote materials and not necessarily labour. For small homes, labour can add on at least $100-200,000. There are a lot of other costs you’ll have to add on if you decide to owner build. Then there’s finding the time, energy and skills in project managing, building, logistics and ensuring you keep to budget.



Always check to see what is included in your home package. Is it just a box without fittings, hot water system, bathroom, kitchen? Are double glazed windows, the designs/plans included?

Meet with the builder to find out how they work. Who they are and how their products work.

Contact your council to find out their requirements eg. how close you can build to boundaries

Step 4: Ensure the design will work on your land

Make sure that the designs you’re looking at will fit onto your land.

Look for north facing blocks with good sun as environmental homes are all designed around the sun. Avoid slopey blocks to keep costs down. Does the land come with services (power, water, sewer, phone, gas), connecting to these services can add thousands of dollars onto the cost to build.

There aren’t a lot of project homes which can be built on sloping blocks. Viva Homes can build on sloping blocks but bear in mind it does bump up the price of building.

Step 5: Choose your builder

Have a look at how long they have been building environmental homes. Have a look at a finished home, how long has it been there? Is it professionally finished? Do their designs use the sun, cool in summer and warm in winter? Are they functional? Beautiful? Robust?

Choose your home design and get a quote! Act! Procrastinating won’t get your home built!

Important Warning!

Many people come up with a wishlist for their home and then have a designer or architect design their home. DON'T DO THIS WITHOUT INCLUDING A NATURAL/EARTH HOME BUILDER!! If you want to save time and lots of money... involve a builder at the design stage who can ensure the designer keeps to your budget. It's well and good to design your grand dreams but there's no use unless it's reasonable to build for your total budget! For more info and examples, refer to our page on 'to design or buy'. A possible cheaper alternative is to ask the builder if they have any designs. This can save you over $30,000 in getting an architect to draw up from scratch a home for you. Builders who design and construct will save you thousands in drawings as well as costs in building. They've done it before so it's cheaper.
