Building a granny flat in Melbourne can be an excellent way to add extra living space, create rental income, or accommodate family members. But while the benefits are clear, the costs can quickly add up if you’re not careful. From council approvals and design choices to materials and construction techniques, there are many opportunities to cut costs without compromising on quality. Whether you’re thinking of a basic design or something more high-end, this guide will walk you through practical tips to keep your budget in check when creating your perfect secondary dwelling.
Start with Smart Design Choices
One of the biggest ways to save from the outset is by choosing a compact, efficient layout. If you’re considering a tiny home in Melbourne, think carefully about your floor plan and how every square metre is used. Open-plan designs help save on walls and materials, while built-in storage and multi-purpose furniture can free up valuable space.
Avoid overly complex designs with multiple corners or varying roof heights. These elements may look good on paper but increase labour and material costs significantly. A simpler structure can be just as stylish and far more cost-effective.
Also, consider standardising window and door sizes. Custom features tend to cost more, while standard fittings are generally more affordable and readily available, helping you stay within budget.
Choose the Right Type of Build
Opting for pre-fabricated or modular studio cabins can dramatically lower construction costs and build times. These builds are designed for efficiency and often require less on-site labour, which reduces the overall project cost.
Prefab options also reduce waste and are produced in controlled environments, leading to better quality control. Plus, installation is usually faster, meaning you can move in or start earning rental income sooner.
Whether you’re after a single-room setup or something more versatile, there’s a prefab design to suit a variety of needs – all while saving money on build time and tradespeople.
Plan for an Essential Granny Flat, Not a Luxury Build
It’s easy to get carried away with the latest finishes and luxury fittings, but sticking to an essential granny flat layout can be your biggest money-saver. Focus on what you truly need—bedroom, bathroom, kitchenette, and a small living area—rather than extra rooms or expensive upgrades.
Pick cost-effective, durable materials that provide long-term value. For example, vinyl flooring or laminate benchtops offer aesthetic appeal at a fraction of the cost of hardwood or stone.
Remember, your goal is functionality first. You can always upgrade or personalise interiors later when your budget allows.
Think About Long-Term Savings
It’s not just about building cheap—it’s about building smart. Investing in insulation, energy-efficient windows, and LED lighting might cost a bit more upfront but will save significantly on energy bills in the long run. Many lifestyle cabins come with these features pre-installed, offering great long-term value.
Also consider water-saving fixtures like dual-flush toilets and low-flow showerheads. These additions are affordable and help keep utility bills down month after month.
And if you’re looking to rent the flat out, low ongoing maintenance means less hassle and cost over time, making the entire investment more profitable.
Keep the Size Within Permitted Development Limits
In Victoria, granny flats (or secondary dwellings) often come under specific size and planning regulations. By keeping your structure within the permitted limits, you could avoid the cost and time of applying for planning permits.
A deluxe cabin might be tempting, but going just a few square metres over the limit can create complications. Work with a provider that understands the regulations in your local council and can help you navigate them to save on unnecessary application costs.
Choosing a provider that offers ready-to-install cabins within these guidelines will save you a lot of time, money, and potential frustration.
Consider Multi-Purpose Use for Greater Value
Want to make your investment work harder? Think about building a family cabin that serves more than one purpose. A space that doubles as a home office, guest house, or teenage retreat adds greater value and flexibility, especially if your circumstances change down the track.
Dual-use designs are becoming more popular in Melbourne, and with smart planning, you can adapt your cabin to meet lifestyle changes or rental demand.
Multi-functional builds are especially useful if you’re planning to rent on Airbnb or need occasional extra accommodation for family. Getting more use out of the same space increases return on investment.
