We all eventually need to move into a bigger place and or/modify our dwelling to accommodate our current personal needs. It’s one thing to be in your 20s, live in central Perth, and get by with a small, one-bedroom apartment that you rented out from a friend at half the price (ask me how I know). But it’s something else entirely to now be in your mid-30s, be married, expect a new member of the family, and have new and sometimes scary opportunities for expanding on your career trajectory.
Your life probably doesn’t resemble the one you set out for yourself, ten or fifteen years ago. So why would you expect that the functionality and square footage of your current dwelling remain suitable for your needs? In truth, like the majority of Australian homeowners, at some point you too will start considering the prospects of moving into a bigger place. But the real estate market, at least in central locations suitable for commuting, is in a bad place right now, and the majority of families are simply unable to afford moving, at least for the foreseeable future.
Things could change, sure. But as of 2026, the best option on the market, for most of us, is to just invest in 2-bedroom granny flats developed by a professional house and granny flat builder in Sydney. Accessory dwelling units are flexible constructions that usually can be completed only by making use of a CDC. They are relatively cheap to build, they can potentially significantly enhance the valuation of your primary dwelling, and they can be rented out. So, they are all the rage right now.
When Should You Go for Them?
Most people invest in 2-bedroom granny flats because they either want a building that can produce a constant, reliable secondary income, or they want to expand on the usable square footage of their primary dwelling. In my case, the main reason why we needed the services of a house and granny flat builder was because of space constraints and a need to accommodate visiting relatives.
Our three-bedroom dwelling got a bit cramped after the birth of our second child, and after a few stressful months at work, it became apparent to us that we couldn’t take any more time off in order to deal with family emergencies. We needed a nanny, but there was no one around who would fit our budget and demands. My family wanted to help; after all, both of our parents were retired and would gladly come here to occasionally help with their grandchildren. But where could we house them?
For us, 2-bedroom granny flats represented a cost-effective way to keep our family close, support the growth of our children and also expand on the property’s usable space. Now that our kids are grown up, and their grandparents are not visiting as often as before, the ADU is available as a potential rental for students or small families. We are slowly getting our money back, one month at a time, and if we ever decide to sell, the investment we made in the granny flat will likely reflect in the price we could ask for our property.
Your Situation Might Be Different
In our case, we considered investing in 2-bedroom granny flats in order to keep our parents around and let our children grow up in the company of their extended family. It was probably the best decision we ever made. But the benefits of granny flats don’t just stop at accommodating family members.
ADUs represent an investment characterised by a positive ROI that eventually, in the right set of circumstances, will likely start to make a profit. Weekly rent in Sydney, for suburbs such as Parramatta, is currently hovering around A$750 and climbing. Unlike house prices, which are down almost 10% in the last 12 months, rent is still going up, slowly but steadily. And for a good reason, really. Whether the current housing crisis continues or not, Australian cities are still expanding and people still have a need for cost-effective accommodation.
Let’s say you don’t want to rent out your granny flat at current market prices. Maybe you want to accommodate long-term tenants, so you offer a good deal at A$600 per week for 2-bedroom granny flats, with year-round occupancy, which will put your yearly rent revenue at A$31,200 per year. Sure, you will still need to account for expenses and taxes. But even so, realistically, you will eventually recoup your money and then some.
Are There Instances in Which 2-Bedroom Granny Flats Are Not Suitable?
Yes, of course. Each situation is different, and the characteristics of your dwelling could have a direct effect on the feasibility of a house and granny flat builder in Sydney. An ADU might not be appropriate if:
-
You need extra space immediately and you don’t want to wait for months at a time till the paperwork is ready and construction is complete
-
Your dwelling is built on a lot with significant drainage or setback constraints
-
You are not looking for an independent property, adjacent to your main dwelling
For most people, the services of a house and granny flat builder will be more than worth it, but ADUs are not the only option you have available for expanding on your property’s usable space.
-
Home extensions, for instance, can be a way to build additional living areas to your existing house.
-
Basement conversions are becoming a popular choice for transforming unused spaces into usable living containments
-
Garage conversions can often be cheaper than ADUs, as they already have the foundational structural elements required for in-depth modifications.
But all these alternatives have one issue. They need to meet Sydney’s residential building requirements, and in some cases (as is the case with home extensions) they might require council approval. ADUs are fast to build, cheap, require less paperwork than other alternatives, and are sought-after by potential real estate buyers. So, they are one of the best investments available right now for the average Aussie family.
