Structural Work
Structural changes to a home typically represent the largest expenses during a renovation. These changes include anything that impacts the foundational integrity, such as removing or repositioning load-bearing walls, foundation repairs, or underpinning work.
A. Load-Bearing Walls And Beams
Removing or altering a load-bearing wall is a common part of many renovations, especially when homeowners are trying to open up spaces or create an open-plan living area. This can be an expensive endeavour as it often requires the installation of new beams or supports to maintain the structural integrity of the house.
Engineers and architects will be required to design these changes, and you’ll also need qualified tradespeople such as carpenters and steel fabricators to do the work. Depending on the size and complexity of the project, these costs can range from several thousand to tens of thousands of dollars.
B. Foundations
Foundation repairs or alterations can also drive up costs significantly. If your home’s foundation is unstable, or if you need to change the way the house sits (such as adding a second storey or extending the footprint), the price tag can be considerable.
Foundation work often requires extensive excavation, the installation of new footings, and possibly even underpinning, which involves strengthening the current foundation. Such work often requires specialised equipment, skilled labour, and permits, all of which contribute to the overall expense.
Roofing
The roof of a house is one of the most critical elements, and replacing or repairing it is often among the most expensive aspects of a renovation. Roofs can be costly to replace or repair due to the materials, skilled labour required, and the need for scaffolding or special equipment to carry out the work safely.
A. Roof Replacement
If the roof is old, damaged, or unsuitable for your needs, replacing it can be a large expense. The type of roofing material you choose—whether it’s tiles, metal, or a more specialised option—will heavily influence the cost. Roofs made from terracotta tiles, for example, are generally more expensive to replace than a simple tin roof.
B. Repairs And Upgrades
Sometimes, instead of replacing an entire roof, it’s possible to carry out repairs or upgrades, such as fixing leaks, adding insulation, or upgrading to a more energy-efficient option. These projects still involve skilled tradespeople and materials, which can contribute to the overall cost of the renovation.
Kitchens And Bathrooms
The kitchen and bathroom are often the heart of any home renovation, and these spaces typically represent a significant portion of the overall cost. Both the kitchen and bathroom renovations involve a wide range of elements that can quickly add up, such as appliances, cabinetry, plumbing, flooring, and finishes.
A. Kitchen Renovations
A high-quality kitchen renovation is expensive because of the variety of elements involved. You will likely need to replace or upgrade major appliances such as ovens, dishwashers, and refrigerators, all of which can be costly, especially if you opt for high-end or energy-efficient models. Custom cabinetry and benchtops, particularly those made from granite, marble, or other premium materials, can be extremely expensive.
Moreover, plumbing and electrical work are often required for both kitchen and bathroom renovations. New wiring, plumbing fixtures, and gas lines can add significant costs to a kitchen renovation, particularly if the layout is being changed, which often involves running new pipes or rewiring electrical circuits.
B. Bathroom Renovations
Bathrooms are generally smaller spaces, but they can still be costly to renovate. High-end materials like marble, luxury showers, bathtubs, and custom cabinetry can drive up the price. Additionally, if any plumbing or electrical work is involved—such as moving pipes or adding new circuits for heated floors or lighting systems—the costs will rise.
Flooring
Flooring is another key element that can become quite expensive during a renovation. Whether you’re installing hardwood floors, premium tiles, or high-quality carpet, flooring costs can quickly accumulate, especially if you have a large area to cover.
A. Hardwood Floors
Hardwood flooring is one of the most popular choices in Australian homes, but it can be very costly depending on the type of timber you choose. Premium hardwood options, such as blackbutt, spotted gum, or jarrah, come with a hefty price tag due to the cost of sourcing, manufacturing, and installing these materials. Additionally, any floor preparation, such as levelling or sanding, will add to the cost.
B. Tiling
High-quality tiles, especially those made from porcelain, marble, or other luxury materials, can also be expensive. Tiling large areas, such as the floor of an open-plan living space, will increase costs, as will adding intricate patterns or specialised work, such as mosaics or feature walls. Tiling involves not only the cost of the materials themselves but also the installation labour, which is often more complex than simply laying down timber flooring.
Windows And Doors
Windows and doors play a major role in the aesthetics and energy efficiency of a home. Replacing or upgrading these elements can be quite costly, especially if you choose high-end, energy-efficient options.
A. Windows
Windows are often replaced during renovations to enhance energy efficiency or improve aesthetics. Double-glazed windows, for example, are more expensive than standard single-glazed windows, but they provide better insulation, which can result in long-term savings on heating and cooling costs. Installation, including the removal of old windows and any necessary structural modifications, adds to the cost of this upgrade.
B. Doors
Similarly, replacing doors—whether they’re internal or external—can add significant costs to a renovation. High-quality external doors made from materials such as solid timber or steel can be particularly expensive. Additionally, if you’re expanding the size of doorways or adding new doors to create a larger open-plan living space, you’ll need to factor in the cost of construction work as well as the materials.
Landscaping
Renovating the exterior of a home, including the landscaping, is another major expense. Whether you’re adding a new driveway, building a deck, or creating a garden, these projects can quickly escalate in price due to the need for materials, skilled tradespeople, and possibly permits, depending on the scope of the work.
A. Landscaping Design
Hiring a professional landscaper to design your garden or outdoor space can be expensive, particularly if you want something unique or complex. Landscaping includes the cost of plants, hardscaping (such as paving or decking), irrigation systems, and outdoor lighting, all of which add to the total cost.
B. Outdoor Structures
Building outdoor structures such as pergolas, decks, or retaining walls can be pricey. Custom-built solutions often require skilled carpenters, landscapers, and even engineers to ensure the final result is both functional and safe.
Labour Costs
While the cost of materials is often at the forefront of people’s minds during a renovation, labour costs should not be underestimated. Skilled tradespeople such as carpenters, electricians, plumbers, and builders all need to be compensated for their time and expertise. The cost of these professionals varies depending on their qualifications, experience, and the complexity of the work involved.
A. Hourly Rates
In Australia, labour rates for tradespeople can be quite high. For example, electricians and plumbers often charge upwards of $100 per hour, while carpenters or builders might charge between $50 and $100 per hour, depending on the job. Keep in mind that if the project requires multiple tradespeople working simultaneously or over an extended period, the costs can add up quickly.
B. Project Management
If you choose to hire a project manager to oversee the renovation, this will be an additional cost. A project manager coordinates all aspects of the renovation, ensuring timelines are met, budgets are adhered to, and work is completed to standard.
While a project manager can often save money in the long run by reducing delays or mistakes, their services come at an additional expense, typically around 10-20% of the total project cost.
Conclusion
Renovating a house in Australia can be an expensive undertaking, with several factors contributing to the overall cost. While the specific costs of your renovation will depend on your plans and choices, some of the most significant expenses generally come from structural work, roofing, kitchen and bathroom renovations, flooring, windows and doors, landscaping, and labour.
Understanding these costs in advance can help you plan your budget more effectively and avoid any surprises along the way. By choosing materials carefully, working with reputable contractors, and managing your budget effectively, you can ensure that your renovation is both cost-effective and successful.
Frequently Ask Question
How Does The Choice Of Materials Impact Renovation Expenses?
The choice of materials can have a huge impact on renovation expenses. High-quality materials like granite countertops, custom cabinetry, or premium flooring can be costly, while more affordable options like laminate or engineered wood can keep costs down. The aesthetic you’re aiming for, such as a luxurious or eco-friendly home, will guide your material choices, directly influencing the budget.
Is It More Expensive To Renovate Or Build A New House?
It can often be more expensive to renovate, especially if the home requires major structural repairs or if you’re altering the layout significantly. New construction allows for better control of costs, and modern homes may meet energy efficiency standards, lowering future costs.
However, in some cases, a renovation is more cost-effective than building a new home, particularly if the structure is solid and the changes are cosmetic.
Do Labor Costs Increase The Price Of Renovation?
Labour costs can make up a large portion of the renovation budget. Skilled tradespeople, such as electricians, plumbers, and carpenters, often charge high hourly rates. If your renovation requires a team of workers for specialised tasks, such as custom cabinetry or intricate tile work, the costs can rise significantly.
Labour costs also depend on the region, with some areas having a higher cost of living, which translates into higher wages.
