How Much a Duplex Cost in the Major Cities of Australia?

When it comes to buying a duplex in Australia, it is very important to find out how much is the cost of a duplex in the major Australian cities like Gold Coast, Brisbane, Sydney, Sunshine Coast, Townsville, Perth, Central Coast, Melbourne, New South Wales, Adelaide, and the Ipswich, Queensland. 

As the duplexes are two separate houses built on the same parcel of land, they are the best dwellings for those who want to live independently in Australia while having their parents, grandparents, children, or grand-children in their neighbourhood. 

Whatever your reason to buy a duplex in Australia, it is wise to know how much a duplex costs in Australia because this will help you in taking the right decision in terms of finance as well as meeting your accommodation needs properly. 

Another good reason to look for the cost of duplex in the major cities of Australia like Gold Coast, Brisbane, Sydney, Sunshine Coast, Townsville, Perth, Central Coast, Melbourne, New South Wales, Adelaide, and Ipswich, Queensland is the freedom to build your house the way you like. 

No matter which Australian city you choose to build a duplex in Australia, the cost of building a duplex will depend on the common factors like the size of your house, the location of the land, and the current status of the Australian real estate market. 

Keep in mind that here, we are only considering the cost of building a duplex in Australia and this does not include the cost of the land. 

As you already know that you cannot construct a duplex in Australia single-handedly and you will require an architect and a team of labourers. The best way to know the cost of a duplex in Australia is contacting the local contractors and real estate agents. 

For example, if you want to know how much is the cost of a duplex in Gold Coast, you should contact the local contractor and a real estate agent of the Gold Coast. Similarly, if you want to know how much is the cost of a duplex in the Adelaide, Brisbane, Queensland, Perth, Melbourne, and New South Wales, you should contact the local contractors and real estate agents of the Adelaide, Brisbane, Perth, Melbourne, Queensland, and New South Wales to know the exact amount of sum that you need to spend in order to build a duplex. Again, this does not include the cost of the land. To know the cost of the land in the major Australian cities, you need to contact the real estate agents and local governing body of a particular city you are considering to have a duplex. 

Another good reason to contact the local contractors or the real estate agents of the region you want to build your duplex is the assurance that the duplex will be built exactly the way you want very quickly in a safe and cost-effective way. This is because the local contractors and the real estate agents of the major Australian cities are duly insured to cover the damages or accidents that may occur during the construction of the duplex. However, if you want to hire the local construction team personally, you must consider their hourly rates which depend on their expertise and the city you are considering to build a duplex. 

Here are the types of labour teams that you need to hire in order to build a duplex in Australia on your own. 

  • Masons
  • Carpenters 
  • Excavators
  • Electricians 
  • Plumbers
  • Painters 
  • Glass Workers

To know the total cost of these labour teams, you need to use Google to find their contact numbers so that they can tell you their hourly rates.

For example, if you want to know the cost of a duplex in Sydney, Sunshine Coast, Townville, or Perth, you need to contact the masons, carpenters, excavators, glass workers, electricians, plumbers, and the painters of the Sydney, Sunshine Coast, Townsville, and Perth to know how much a duplex cost in their respective cities. 

Apart from these costs, you should also keep in mind that the cost of the second-floor of your duplex will not go lower than the price per square foot of the first-floor construction. Generally, the price of the construction of a second-floor of a duplex will go up to twenty percent higher if you use the same quality of materials. The extra costs are due to the additional foundation required to bear the extra weight of the second-floor of your duplex.

Take note that the cost of the duplex in any Australian city largely depends on the cost of the real estate in that city. So, if you want to know how much the duplex will cost you in Ipswich, Queensland – the answer will depend on the cost of the real estate in Ipswich, Queensland. The same concept applies to the cost of the duplex in the Central Coast of Australia. It means, it depends on the cost of real estate in the Central Coast itself. Again, it is worth noting that the cost does not include the price of the land and the cost of additional amenities like building the gardens, parking etc. 

If you do not want to take the charge of constructing a duplex in Australia yourself, you should approach the local architects and the contractors of the city to give you the estimate of the costs. 

Though the local architects and contractors charge a fee, they do the following things on your behalf in a professional manner. 

  • They find out the scope of the duplex construction. 
  • They calculate the initial cost.
  • They design the duplex layout and floor-plans.
  • They consult the engineers and local governing bodies for the approval of the duplex design. 
  • They take all the required approvals and complete the documentation for the construction of the duplex. 
  • They supervise the construction of the duplex. 
  • They coordinate with the local contractors to keep things on track. 

The local contractors also do a lot of things on your behalf in a professional manner. 

  • They manage the daily construction activities. 
  • They procure the required construction materials and services. 
  • They coordinate with the labourers to build the duplex the way you want. 
  • They take all the local permissions and approvals for the utility installations like gas connection, water connection, electricity connection, telephone connections etc. 
  • They supervise labourers’ services and material supplies. 

Besides the hourly rates of the labourer teams, local contractors, real estate agents, architects, the cost of building materials, and the cost of the real estate in the city, there are many other factors that affect the cost of your duplex construction. For example:

The Size of the Land

If you want to build a duplex on a smaller size of land, it will cost you less than constructing a duplex on a larger size of land. If you want to construct a duplex on a bigger size of land, it will cost you more than constructing a duplex on a smaller size of land.

The Size of Duplex

The cost of a duplex largely depends on its size. The bigger your duplex size, the more the construction costs. The smaller the duplex size, the lesser the construction costs. 

The Type of Building Materials 

The type of building materials also play a major role in increasing or decreasing its cost of construction. If you are considering higher-quality building materials for your duplex, surely, the cost of the duplex will increase. Similarly, if you are considering the average quality of the building materials, the cost will be average. 

The Location in City

The cost of constructing a duplex at the prime location in the Australian city will cost you more than constructing a duplex at the location that is rural or at a distance from the prime location in the Australian city. 

DIY or Let Others Do 

If you take care of the construction of the duplex yourself, it will cost you less as you save the fees of the local contractors and real estate agents. However, you are at the risk of handling the damages or accidents yourself if they occur, in case.  

If you let others do the job for you, it will cost you more but you have the benefit of not handling the damages and accidents yourself.  

So, now you know, how much a duplex will cost in the major Australian cities when you choose to construct it –  no matter on your own or with the help of a local contractor and real estate agent. 

What will be the cost of duplex in the major Australian cities if you want to buy a readymade one? Well, this will cost you higher in most cases since the readymade duplexes are built at the prime locations of the major Australian city. But somehow, if you can find readymade duplexes in the rural areas around the major Australian cities, the cost of the duplex will reduce considerably. So, that is how the cost of a duplex is determined in the major Australian cities. It depends on a lot of factors which I have already mentioned in this blog. 

While looking for the cost of a duplex in Melbourne, Brisbane, Adelaide, or any other Australian city, first decide on the following two things: 

  • Whether you are looking for a duplex at a prime location in any Australian city or at a rural or distant location in any Australian city?
  • Whether you are looking to construct a duplex on your own or want to buy a readymade one? 

The cost of a duplex would increase or decrease in any Australian city, according to your personal requirements and preferences. 

If you want to buy a readymade duplex in any major city of Australia, look for the duplexes for sale in your preferred city online. 

For example: 

  • Duplexes for sale in Gold Coast

  • Duplexes for sale in Central Cost 
  • Duplexes for sale in Melbourne 
  • Duplexes for sale in New South Wales 
  • Duplexes for sale Adelaide
  • Duplexes for sale in Ipswich 

Keep in mind that buying a ready-made duplex or constructing a new duplex at a prime location of any Australian city will cost you more than buying a ready-made duplex or constructing a new duplex in a rural or at a distant location from any Australian city. 

That’s how a duplex costs in and around the major cities of Australia.
