How Much Does It Cost To Build A House?
With so many designer options can be difficult to estimate pricing on new build properties. But just how much does it cost to build a house in Australia?
In this guide we are going to look at the price ranges for building a house in Australia as well as look at the different square footage costs and extra hidden costs that you may not be aware of.
What Is The Cheapest You Can Build A House For?
There are some extremely affordable options out there for people wanting to build their home on a budget. The larger a property gets the more expensive it becomes to build. So if we stay small we can save a lot of money.
The cheapest build I could find was a 3 bedroom house which was 150 metres squared in terms of floorspace. It had an ensuite off the master bedroom and lounge and dining room as well as an outside entertaining area
Building Cost: $117,200
However you also need to take into account the other approximate costs associated with the property. Site Costs (varying) – $10,000 – $70,000 (normal is around $20,000) BASIX – $10,000 Driveways and Flooring – $10,000 So you would generally need to add around $40,000 or more to the cost of the build in extra costs.
The cheapest you can build a house for in Australia is somewhere around $155,000
Cost To Build A House Per Square Metre
A lot of builders and home owners talk about the cost to build a house in terms of dollars per square metre. The way this is calculated is by taking the total cost of the build and dividing it by the total floorspace of the home (not the land). I am personally not a massive fan of these calculations as the cost per square foot for a kitchen or bathroom is going to cost a lot more than the cost per square foot for an empty room. Thus your calculations can quickly become inaccurate if you are creating a large kitchen or bathroom space in the home. None the less it is an important measurement so here is a rough estimate of cost per square metre different types of houses may cost you.
Project Homes (basic) – $620-$780/square metre
Project Home (deluxe) – $1,000 – $3,000/square metre
Custom Built Homes – $1,500 – $3,000/square metre
Deluxe Customer Built Homes – $2,500 – $4,000+/square metre
Extra Costs You Need To Take Into Account
There are also some extra costs you need to take into account which could end up costing you a significant amount of money. It is difficult to estimate the costs without knowing anything about your land or your build. But you can use this as a rough guide.
Soil Quality – The above estimations were built on the assumption that your plot of land has M classification soil (the best classification you can get). If your soil is more difficult to work with (eg. Clay, Stones, Boulders etc) then you can expect your costs to increase in the thousands of dollars.
Sloping Of The Block – Best case scenario is that you have a perfectly flat block and there are no additional costs. But if your block is sloping you can expect the estimated extra costs below:
Front to back slope – $6,000/metre slope Side by side slope – $9,000/metre slope
It is also important to note that a lot of project builders will not build on a block with a greater slope than 3 metres.
Soil and Contour Test – This test will cost you around $1,500-$2,000 and is done to test your soil quality and the contour of your block.
Bushfire Prone Areas – If you have a Bushfire Attack Level (BAL) attached to the property then there will be extra costs to ensure the property is safe during bushfires.
Flood Prone Areas – If your property is in a flood prone area then measures must be taken to prevent deaths during flooding. This often means raising the home and will incur extra costs as well. Read more about the hidden costs when building a house
How Much Does It Cost To Build A 4 Bedroom Home
From my research I found that:
4 bedroom homes range from $130,000 (160sqm) to $190,000 (300sqm) when looking at the most basic range of properties. When looking a wider acreage properties costs went up to $230,000.
Obviously the price also increases as the property and it’s fixtures become more luxurious. Please be aware that you still need to add the extra costs such as site fees, BASIX and flooring/driveway to these prices to get the full price of the property.
5 bedroom homes start from around $195,000 but tend to be over the $200,000 price range
Please be aware that you still need to add the extra costs such as site fees, BASIX and flooring/driveway to these prices to get the full price of the property.
Extra Costs When Going With A Builder Instead Of A Project Home
Some people may prefer to go with a custom design and builder instead of building a project home through a larger company. This may be driven out of necessity (block slopes too much) or desire (wants a custom design). It is important to note that there are some extra costs that will be incurred when going through a builder instead of a project home.
Home design – Firstly you will need to pay to have the home designed. This usually means employing an architect, and they don’t come cheap.
Materials – Project homes buy materials in bulk and are often happy to work with cheaper materials. A custom build it likely to have added material costs.
Project Manager – You may also need to hire a project manager to manage the build.
Labour – Building companies and builders make most of their money in the markups they charge on labour. By going through a builder who hires more expensive subcontractors you may have to pay more in labour costs.
How To Get Quotes For Building Costs
Quotes are hard to obtain online. Few companies reveal their pricing on their website and in most cases you are required to call or visit a show room in order to obtain pricing. However, I found that once I called or attended a show room they were more than happy to go through all the pricing details with me.So it is an extra step but not a hard one. If you don’t want to leave your home simply call up and ask them to email their price list through to you. If required choose a design off the internet and say you are particularly interested in this one design but would like to see pricing for all designs. It is much easier to get quotes from project home companies instead of builders and the pricing is all set out. A builder will need to do more work to estimate pricing and if you aren’t serious you don’t want to be wasting their time.
