You've probably wondered about the nitty-gritty of building a duplex. Well, you're in luck, because today, we're diving deep into this topic. So, grab your hard hat, put on your high-vis vest, and let's get down to business.
Getting Started
First things first, building a duplex in Australia is no walk in the park. It takes planning, knowledge, and a bit of coin. But hey, if you're prepared, you can make it work.
Location, Location, Location
When weighing up the cost to build a duplex, considering the location plays an essential role. As we all know, Australia's a big place, and costs can vary greatly depending on where you want to build. The urban jungle of Sydney is not so complicated! If you drew a circle on a map that’s a 30 minute drive around Sydney Olympic Park, the cost to build will be very similar no matter the location. Opt for a further West or south west, and you might save some serious dough. Further East or north and you'll pay a pretty penny as the design expectations are usually costly. Some other things to consider include:
Population and density - The total population and density in that region and how it affects the sale or rental of the completed duplex.
Supply and demand - are there many duplexes for sale or rent in your location what is your point of difference and are you prepared to rent out if you cant sell or vice versa.
The infrastructure - do council have new and well maintained roads, kerbs and stormwater system. This will make the area more enticing to live in for prospecting purchasers/tenants. The infrastructure is also important to consider as it could make access for construction deliveries and contractor parking easier or more difficult.
The Land Cost to Build a Duplex
Once you've decided on the location to purchase, the next step is picking the parcel of land. You will need to study and consider the land on its merits.
Is their enough area and frontage? Is the land generally flat and only slightly sloping?
A site that’s sloping more than 1 metre will generally cost more to build.
Does the land fall to the front or rear? Will you need a stormwater easement?
Generally the more site constraints and the more difficult to build the cheaper the block (but higher construction costs).
It’s a good idea to have partnered with a building architect or designer to provide advice on this prior to purchase – they will usually help and not charge if they know they are in with a shot for the design.
Design and Size
Now, the design and size of your duplex play a massive role in the overall cost. Are you going for a basic layout or something more fancy? Consider how many bedrooms, bathrooms, and living spaces you want. The more intricate the design, and the larger the dimensions of the duplex is will determine the amount of materials you will need to purchase and ultimately the higher the cost.
Materials Matter
Being a seasoned pro, you know that the choice of materials can make or break your project. The quality of bricks, roofing, flooring, and fixtures can significantly impact your budget. Opting for high-quality materials might cost more upfront but can save you big on maintenance down the line.
The total cost of your duplex design will be affected greatly by the materials chosen to be used in the development. These must be selected with care to find the balance with high quality products and great value.
The Right Consultants / Contractors
The price of building a duplex is influenced by the consultants you choose to hire. Professionals with years of experience and professional skills often charge higher rates, Moreover, the more experienced consultants would provide the most optimum design with a perfect balance of aesthetics, value and buildability, not to mention the ongoing guidance throughout the project.
it is also worthwhile to consider if you will you be engaging all consultants yourself or will you engage a project manager to manage each consultant.
Demolition and site costs
Demolition and site costs are one of the key factors required to determine the cost of building a duplex. It is possible to purchase an existing property with a great looking house that is growing in value and decide to tear it down and rebuild it, resulting in a duplex cost that is low and a sale that is high.
Demolition costs can range from $20,000 to $50,000 depending on the site size, existing buildings size and type as well as location in proximity to tipping and access for heavy vehicles and plant both to the site and in and around the site.
Permits and Approvals
Time for some Paperwork – Before you even think about swinging a hammer, you'll need to consider council permits and approvals as well as payments for levies and fees. These can vary from council to council, so be sure to budget for those pesky fees.
Labour Costs
The labour force in Australia isn’t cheap, and rightly so. Experienced tradies deserve fair pay. Your building team's size and skill level will influence labour costs. Don't forget to include costs for plumbers, electricians, and other specialists.
Contingency Fund
Trust me on this one – always have a contingency fund. Construction is unpredictable. There might be unforeseen issues like dodgy soil, hidden asbestos, weather delays, rate rises or other surprises. They call it “Saving for a rainy-day” for a reason so having a back up fund can save your bacon.
Sustainability and Energy Efficiency
Moste prospective purchasers and tenants are cluey into the importance of sustainability and energy efficiency. Consider investing in solar panels, insulated walls and windows as well as energy-efficient appliances. It may cost more upfront, but it'll pay off in reduced utility bills and a smaller carbon footprint.
Interior Fit-Out
Now, don't skimp on the interior. Kitchens, bathrooms, and flooring can gobble up your budget quickly. Think about what will attract future tenants or buyers. You might need an additional consultant here or you may take a punt with the builder who can take on an extra hat drop his tape measure and pick up his swatches.
Landscaping
Don't forget the exterior, either. Landscaping can make your duplex stand out and add value. Budget for gardens, outdoor living spaces, and a bit of greenery. Using small pot sizes will have a lower costs upfront but larger pot sizes will provide a more luxurious feel to the landscape – a balance is essential.
Hidden Costs
Remember, there are always hidden costs. Legal fees, insurance, connection fees for utilities – they add up. Be diligent in researching and budgeting for these less obvious expenses.
