19th December 2024

Building a dual occupancy home is a smart choice for many Australians, offering opportunities for multi-generational living or rental income while maximising land use.

However, understanding the costs involved is crucial to ensuring your project stays within budget. From land preparation to construction and council fees, there are many factors to consider.

In this guide, we’ll explore the key components that influence the cost of building a dual occupancy home and share practical tips to help you budget effectively.


Factors influencing the cost of building a dual occupancy home

Land preparation & site conditions

Preparing your land is one of the first expenses to consider. Its cost depends on factors like:

  • Soil quality: Poor soil may require additional excavation or reinforcement

  • Site accessibility: Hard-to-reach sites or sloping blocks can incur additional preparation costs

  • Demolition: If there’s an existing structure on the property, you’ll need to budget for demolition and waste removal.

Construction costs

Construction costs should form the largest portion of your budget, so be aware and plan accordingly. These costs depend on:

  • Size and complexity: Larger homes with intricate designs are more expensive to build

  • Materials: Premium materials add aesthetic appeal but come at a higher price

  • Labour: The level of expertise required can influence labour costs.

If you’re wondering, “how much does it cost to build a dual occupancy home?”, the answer depends on a variety of factors, including the specifications, finishes, and overall design choices.


Utility connections & infrastructure

Dual occupancy homes require independent connections for utilities like water, electricity, and gas, which can increase costs. Additional infrastructure expenses may include:

  • Stormwater and sewerage upgrades

  • Driveway construction

  • Fencing and landscaping

Working with an experienced builder like Marque ensures all these details are accounted for early in the process.


How much does it cost to make a dual occupancy home in Melbourne?

The cost of building a dual occupancy home in Melbourne can vary significantly depending on factors such as location and design choices. Understanding these variables is key to creating a realistic budget and planning your build effectively.

Base construction expenses are influenced by the size and specifications of your home. Homes with custom designs typically require additional investment to accommodate bespoke features and personalised layouts, which add both functionality and aesthetic appeal.

Additionally, costs can fluctuate based on your specific preferences, the characteristics of your land, such as soil quality and slope, and local market conditions. By factoring in these elements early, you can ensure your project aligns with your vision while staying within budget.


Hidden costs to watch out for

Hidden costs can catch homeowners off guard. To avoid surprises, consider:

  • Soil testing and surveys

  • Landscaping and fencing

  • Legal fees

  • GST and taxes

Working with a trusted builder ensures transparency, helping you prepare for any hidden expenses while saving both time and money.
