    When you build a new house, the base price that builders list on their websites does not define how much money your particular home will cost to have all the finishing touches added. If you are interested in acquiring this service, you should check into purchasing "turn-key" solutions. The majority of the time, you will be required to pay for your home according to a predetermined payment schedule.

    In Australia, the cost of constructing a home is between $1250 and $1700 per square metre on average. This is the case for a normal home construction project that does not include any high-end finishing or additional construction fees.

    Before you sign the contract to build your new home, however, you need to take into consideration these unaccounted for things in your budget if you are building a home and want to obtain a better understanding of how much has to be budgeted. These are broken down into four distinct categories: the site, the prestart, the variations, and the finishing costs. After providing a brief overview of provision sums and premium expenses, I will proceed to explain each in further depth. If you are still uncertain, it is best to seek the assistance of a building broker.

    New Home Cost

    The cost of a typical house made of double brick will vary depending on the type of finish you want, as well as whether or not you go for a prefabricated or a custom home. The cost of a newly constructed home in Australia, on average, is. The following tables provide an estimate of how much it would cost to build a house on a flat site using a variety of various finishes per square metre.

    Be mindful, however, that additional costs, such as retaining walls, landscaping, and finishes that aren't the industry norm, might drive up the overall basic price significantly.

    Provisional Sums And Prime Costs

    Who is responsible for explaining, prior to delving into the costs, the distinction between the provisional sums (PS) and the prime cost components (PC)? These phrases are used multiple times throughout a construction contract, and they frequently lead to misunderstandings.

    The builder's preliminary estimate of the amount of money needed to complete a specific task or pay for a particular material or service is referred to as a provisional sum. It was not possible to determine an accurate cost while the contract was being provided, thus it was incorporated into the first agreement.

    In the vast majority of instances, constructors will make use of interim figures for the site works. For instance, a site may appear relatively flat and free of debris, but when workers begin making preparations to lay the slab, they may discover a significant amount of rock that must be excavated.

    Because of this, it will result in you having to pay an additional payment on top of the price that was agreed upon in the contract.

    Items with prime costs are ones whose prices may be adjusted before the game begins. They consist of things like tiles, doors, and faucets, among other things. Whenever a client signs a contract with our company, we always provide them a rough estimate of the whole cost. If you modify these premium items during the pre-start meeting, it is possible that doing so will either cost you additional money or save you some money depending on the finishes that the builder is initially giving you with.

    In order to prepare for any shifts in the provisional sum and prime cost item of your building contract, it is recommended that you include a buffer amount in your budget.

    Site Costs

    The cost of building a house is increased by site costs, which are expenditures incurred to prepare the plot of land. I have not gone through the costs of demolishing houses because I am not going to be doing that here. Your builder will typically finish these, and in the majority of instances, the cost is added on top of the build fee rather than being included in the base price.

    However, before speaking with a builder, you might want to have a site study done first. Site costs for an average block in Perth typically fall somewhere between $14,000 and $20,000, with the average cost coming in at $16,000. These are the following:

    • Retaining walls
    • Site survey
    • Soil test if needed
    • Site clearance (trees, roots, bushes)
    • Service connection (water, sewer, power, gas)
    • Fences

    Pre-Start Meeting Costs

    At this point in the process, when your house plans have been finalised and approved by the local government, the pre-start meeting will take place. At this point, you will be ready to make significant decisions on the colours, styles, and types of materials and fittings. The Home Building Contracts Act from 1991 stipulates that the builder is obligated to include a breakdown of these charges inside the contract. Even though the builder has already included in these extra charges, the materials, fittings, and fixtures that come standard in the base contract package are often the least expensive options available. However, there is a possibility that you will wish to change some of these options.

    It comes at an additional fee equal to the difference in the costs of the items. The vast majority of builders work with a select group of vendors to procure materials like tiles and fittings. Before the last pre start meeting, they will typically provide you a book to create and look at your selections from before the conference begins.

    As a rule of thumb, you should include in an additional 5 percent of the total price of the contract for prestart. It depends on how much, if anything at all, you modify, and I have included some items below that would catch you in a pre-start meeting in case you did make any changes.

    Electrical Changes Costs

    If you decide to change your lighting plan from what was first drawn, this will result in one of the more expensive parts of the prestart process. Everything hinges on the provisions that are outlined in the contract specification. For instance, if it only allows for one normal light per room, but you wish to have many downlights, the additional expense could build up pretty quickly.

    Roof Material Costs

    It is important to keep track of the initial allowances for roof coverings that your builder has provided you with because switching from tile to Colorbond or vice versa may result in additional expenses.

    Tiling Costs

    Customers frequently voice their dissatisfaction with the tiling, and the primary reason for this is that they do not comprehend how the builder arrived at the price for the revisions from the original contract. Your contract will therefore include an allowance for a set tile size and a tiling amount per square metre. Additionally, the tiling amount will be specified.

    You make the decision to upgrade to a greater tile size while maintaining the same cost per square metre for it. However, this will need the purchase of additional tiles, which will then need to be trimmed down in order to fit into the same space that the smaller tiles might have occupied without any modification.

    In addition, the labour cost per square metre might vary depending on whether the tiles are rectified or non-rectified, which can be a significant difference. The reason for this is that it is significantly more difficult to place non-rectified tiles flat without leaving a discernible level difference between each tile.

    Fixtures And Fittings Costs

    You make the decision that you want elegant faucets and showerheads that are outside the industry norm in each of your bathrooms. When compared to the price stated in the first contract, these have a significant impact on the overall cost, which now takes into account the builder's preset mass bought range.

    The builder receives significant savings on those items, whereas your one-of taps only receive relatively little reductions in price. Additionally, if the product is more difficult to instal, there is a possibility that the labour expenses will increase.

    Kitchen Pre-Start Costs

    Depending on the quality of the item you are going for and what was in your initial specification written out in the contract, adjustments to your kitchen benchtops, cupboards, and overhead cupboards can easily add up to a significant amount of money.

    Variations To A Contract

    Changes made to a contract after it has already been signed, either before or after the prestart, are referred to as variations. Variation costs are the kinds of charges you want to steer clear of at all costs. Markups on deviations often range from 20 to 25 percent when it comes to construction companies. In addition to this, builders will often charge an additional variation fee of $250 for each change.

    It is expected that your contract would detail these costs; therefore, you should be aware of them before signing the agreement. Any changes need to be put in writing, with an explanation of the terms, and consensus needs to be reached among all parties involved.

    One example of a variation may be something substantial, such as the addition of an additional room, or it may be something insignificant, such as the modification of the tile grout colour.

    Unfortunately, variations frequently lead to a disagreement between the maker and the customer. One scenario in which this might occur is one in which the builder accepts a verbal variation, but the client later refuses to pay either the full amount or a portion of what the builder is charging for the work.

    Finishing your Home Costs

    If you and your builder have not agreed upon a "turn-key" plan, then there will be additional expenses associated with the completion of your home. To finish the house, you need allocate somewhere between 10 and 20 percent of the total cost of the house in your budget. The finishing touches include things like carpeting, painting, landscaping, fencing, reticulation, air conditioning, pavement, and a driveway, if one is required. Other finishing touches include reticulation and air conditioning. The cost of air conditioning is determined by the requirements. If you only need one HVAC system, a split system will be more cost-effective than a ducted system for the entire home. The supply and installation of ducted air conditioning in a typical four-bedroom, two-bathroom home will run approximately $9,000.

    I have included a table below with some information that you should be aware of as well as some very preliminary pricing estimates next to each item in the table. Please keep in mind that every house is unique, and that the cost of these homes might range greatly.

    The Rising Cost Of Materials

    The most significant change brought about by the post-COVID environment is the increase in the costs associated with the supply chain.

    The vast majority of client contracts are signed well in advance of work beginning, locking in the costs at that particular market pricing. Unfortuitously, builders are required to take these costs on themselves a year later rather than passing them on to the customer when the construction first begins.

    One regional builder reported to that the cost of supplies had increased by anywhere from 15 percent to 45 percent, and that some suppliers had raised their prices for the same item three or four times in the space of just a few months.

    In addition, many products that were specified in building contracts when they were signed, such as particular kinds of lumber, are not currently available.

    In certain instances, the costs of the building materials remain the same, but the prices have increased. Even if the price is ten times greater than when they signed the contract, the builder will still be required to pay the new, higher cost. Even though the item may be available from the client's point of view, this does not change the fact that the builder must pay the new, higher fee.

    The proprietor of the company lamented that their profit margins were shrinking to such an extent. "Contracts don't allow any mobility for shifting expenses onto the client, therefore in order for us to survive, we're dependent on being able to improve the margin on the following work."

    "All it takes is just one customer to be late on a payment, and that might mean the death of the firm," one person once told me.

    "Some builders are walking away from jobs and giving back their contracts, despite the possibility of being brought to court," because they do not want to risk losing everything.

    According to the proprietor of the company, an increasing number of builders are being obliged to adjust their legal strategy when taking on new work.

    They do not run the risk of losing money because they use a contract type known as cost plus, which allows the client to be paid for hours and labour while the builder charges for materials at the very end of the construction rather than at the very beginning.

    On the other hand, the administration of this sort of contract is significantly more difficult because it mandates the delivery of a comprehensive monthly report to the customer as the work on the project advances.

    Delays In Materials Are Arriving.

    Because of the delays in freight shipment, the builder is compelled to push out the build timelines, which requires them to spend more time on one task before they are ready to go on to the next one. This costs the builder money. In addition to this, they are required to pay employees regardless of whether or not the work is completed.

    Who is prohibited from lawfully charging penalty rates in contracts unless official notices, also known as Extension Of Time notices, are periodically sent to the client, which requires additional administrative labour?

    In some cases, these are things that would ordinarily be able to be picked up at a local hardware shop, while in other cases, they are specialised pieces of larger products, such as the foam that is sandwiched in between double-glazed windows.

    The entire project can be put behind schedule if even a single minor component is missing.

    So How Much Can You Expect To Pay?

    To begin, let's get one thing straight: the basic price that builders promote on billboards and publish on their websites is typically just a starting point, and it does not reflect how much your home will cost when it is completely finished. This information can be found on the builder's website.

    Prices often only contain the essentials when they begin with "beginning from."

    Imagine that you are interested in a complete price that takes into account everything from the carpeting to the landscaping and roadways, as well as the white picket fence that is located in the front yard. In that case, you need to conduct some window shopping for what is known as a "turn-key" package, which indicates that the only thing left for you to do at the end is to turn the key and step inside.

    The cost of constructing a home might vary greatly, particularly with regard to the location in Australia at which the home is to be constructed.

    Additionally, as was stated earlier, the size of the property as well as the quality of the finishes will have an effect on the overall price.

    The figures from the ABS December 2019 Buildings Approvals show that the average price per square metre in Australia was $1393.55.

    The design, the planning permits, the site works, or any cost blowouts are not included in this number.

    The cost of the build element alone is $320,238. This is due to the fact that the average dwelling in Australia is 229.8 square metres in size.

    How Covid-19 Has Impacted Costs When Building A House

    It is difficult to determine exactly how much of an influence COVID-19 has had on the costs associated with building a house; however, it is reasonable to state that it has altered the landscape in many ways, including the closure of borders and the imposition of restrictions.

    As a result of fluctuating exchange rates, disruptions in supply chains, and decreased productivity brought on by COVID-19 restrictions, expenses have increased while the amount of time needed to finish projects has lengthened, which has led to an increase in the cost of construction. See our list of available builder services melbourne to help you make an informed decision for your treatment.

    In the next couple of years, it is anticipated that the shortage of supplies and labour would cause housing construction costs to skyrocket to much higher levels.

    Believe it or not, prior to the introduction of Covid 19, almost twenty percent of Australia's structural lumber was imported from another country, the majority of which originated in Europe. Despite the abundance of trees in Australia.

    The price of timber has increased by between 30 and 40 percent over the past six months, which is a phenomenal trend that is being observed all around the world.

    The COVID-19 epidemic coincided with a surge in home construction in important overseas markets including the United States and Canada, which meant that overseas suppliers had been unable to satisfy this shortage. The boom in residential development here during the pandemic occurred at the same time.

    According to a housing industry economist, the worst of Australia's timber shortage is already behind the country. A drop in the prices of timber imported from other countries, improved planning on the part of builders, and new support from the federal government are all factors that are likely to lead to reduced timeframes for residential construction projects.

    An economist at the Housing Industry Association (HIA) named Angela Lillicrap stated that even though it would take some time for the supply chain to fully correct, the domestic market would eventually feel the effects of a drop in timber prices overseas. This prediction was made despite the fact that it would take some time for the supply chain to fully correct.

    The recent commitment by the federal government of $15 million to transport timber that has been damaged by bushfires from Kangaroo Island to timber mills on the mainland has been hailed as a significant step towards alleviating the current timber shortage.

    Although it will take years to move all of the lumber off the island, it has the potential to enable the construction of up to 10,000 homes made of wood.


    It is highly recommended that you seek the advice of a builder or contractor. They will be able to present you with an estimate once they have taken into account the size of your home, the materials that you select, and the amount of labour that will be required.

    It is crucial to remember that prices might vary substantially based on where you live, so it is prudent to obtain multiple estimates before selecting a builder. We sincerely hope that this article has assisted you in gaining a better idea of the amount of money that would be required to construct a house in Australia.
