What is the Cost to Build 2 Townhouses, Melbourne, Australia?

In this section, we will look at all the factors that affect the cost to build two houses in Melbourne and provide you with a cost estimate for building dual occupancy housing.

The Cost of Construction

Typically, construction costs make up a significant cost for two townhouses in Melbourne. The cost to build a dual occupancy housing unit accounts for about the majority of the total cost.

In general, for a single-story building that uses basic materials for construction, the average price is $1000 per square meter. An upmarket luxury build could cost you up o $3000 per square meter for a double storey dwelling.

In a typical suburban area, a dual occupation building or two townhouse developments cost about $1350 per square meter, or $1700 with site costs.​ An average 3 bedroom townhouse will cost $250,000 upwards per unit.

The cost to build two townhouses in Melbourne varies and depends on multiple factors such as:

  • type and quality of materials used;  
  • required design elements;
  • the cost of labor in the area;
  • development sites cost;
  • the cost of land;
  • other costs.

Type and Quality of Materials Used

Your building costs will increase if you decide to go for better-quality materials. For example, building two townhouses in Melbourne with essential build materials like brick and wood may cost you around $150 - $300 per square metre, whereas using costlier material could cost almost double. It is best to look for builders cost crunches online to see the cost breakdowns of different materials used for building townhouses.

Required Design Elements

Townhouse layouts are costlier to design if you want them to stand out. For instance, you may opt for more complex architecture with more expensive materials and design elements like high-end kitchens and bathrooms, fancy tiles, and other cost-intensive features.

The Cost of Labor

If you decide to hire a contractor for your project, it will add costs to your final price as the cost of labor can be pretty pricey. Normally, the cost to build a townhouse in Melbourne for a 100 square meter project could cost you about $25,000 -$50,000.

Development Site Cost

The cost of buying a development site for building two townhouses in Melbourne will affect building them. It is recommended to hire town planners prior to the purchase as they can advise buyers which developments are allowed.

You can save on costs by buying an existing house for redevelopment. For example, the price to purchase and redevelop an existing house in Melbourne is estimated at around $100 per square meter whereas the cost to build new townhouses is estimated at around $150 per square meter.

The Cost of Land

The cost of land is another major cost when building two dwellings. So how much does it cost to acquire land in Melbourne? The price of land fluctuates depending on many factors, mainly location and availability. The price ranges between $150,000 and $875,000.

Keep in mind you will be charged an extra cost if you plan to build a new house or multiple buildings in a more popular area with high demand for housing projects. However, if you go for less popular areas (for example flood-prone areas), you will pay less for the land

As with any construction project in Australia, you'll need to check local planning laws when buying land for two units and ensure appropriate planning permits.

Other Costs

In addition to construction costs and the cost of the land, you need to take into account several other factors that will affect the final price, such as:

  • Land tax
  • Town planning permit
  • Goods and service tax
  • Legal cost
  • Site management

The Hidden Cost of Building a Duplex or Multiple Townhouses

When building a duplex, multiple townhouses, and multi-unit buildings, there are some hidden costs people tend to forget about, such as

  • The cost of demolishing an existing house before building a new one.
  • The cost of making infrastructure improvements. This may include upgrading public services like power, water supply, etc.
  • The cost of property advertisements for selling or leasing out your properties.

Another important cost that is peculiar for this type of property only is the subdivision of a property.

Property Subdivision Cost

Subdivision of a property isn't straightforward and includes multiple costs such as consulting fees and town planners.

In order to subdivide a property, you need to pay an application fee and have it approved. After that, you will have to hire a surveyor who will cost you about $2,000 -$3,500. Then comes the cost of land division itself at approximately $5 per square meter followed by a cost of land survey (if the surveyor didn't do it).

How to Reduce Costs When Building Townhouses, Melbourne?

When it comes to the build price of two or more townhouses or multi-unit buildings, you should keep in mind that there are several ways you can reduce your construction cost.

First, you can choose to build townhouses instead of units. Townhouses are larger than units and cost less per square metre because the cost is divided between two properties.

You can also opt for modular construction instead of the traditional brick-by-brick building, which reduces cost. Modular home builders in Melbourne use prefabricated construction to keep costs low.

You can also save on the cost by building dual occupancy homes instead of two separate properties. Of course, this will depend on your requirements and living arrangements.

Finally, you can choose to build smaller dwellings that cost less than large properties.

Materials, Furnishings, and Appliances

You can also save a significant amount of money if you purchase all materials yourself. Materials manufacturers offer volume discounts when you buy in bulk, significantly reducing the final purchase price.

The cost of furnishing and appliances vary greatly depending on whether you purchase them one by one or in bulk. For example, suppose you need to buy kitchen cabinets and appliances for two townhouses. In that case, cost savings are maximized if you purchase these items simultaneously, which directly impacts the final purchase price.

How to Make Sure Your Townhouse or Duplex Development Project Pays Off?

If you're wondering whether your investment will pay off, contact a respected company in the construction industry. From cost estimation to cost control and even a feasibility report, they will take care of every aspect of the construction process from start to finish.

In addition, cost consultants can give you valuable advice on reducing costs when building multiple units and townhouses and ensure cost savings, which can be used to attract potential buyers.

If you want to sell your development as soon as possible and avoid huge losses, cost consultants will help you achieve the best price for your property by offering cost-effective building solutions.

With their assistance, you should easily overcome any difficulties during cost estimation and cost control.
