Considering an affordable Granny Flat?

Only deal direct with the builders before signing anything:

Over the past decade, affordable housing has become a rising challenge for all Australians, regardless of their age group. First-time buyers, investors, and even retirees are having a hard time finding housing solutions that do not compromise their quality of life. In dense metropolitan areas, such as New South Wales, housing costs can become quite unaffordable for most people. These prices lead them to believe that the only viable option is moving further and further away from such areas, to settle with an outback lifestyle.

Fortunately, there is a solution that meets both affordability and quality of life, even in densely populated cities – such as Newcastle. This housing alternative is what we call a granny flat. At Grouse House Homes, we specialize in independent and affordable housing, without compromising on quality.

Here’s how we can help you:

  • What is a Granny Flat?

    In simple terms, a granny flat is an independent, detached housing unit, usually located on the grounds of a single-family home, designed to house one or two people. They got their name because they are quite a popular choice for Australian families to accommodate their golden-year members.

  • Granny Flats and their Rise in Popularity

    As we mentioned before, housing in Australia is currently facing some challenging times. According to the latest 2019 ABS (Australian Bureau of Statistics) reports, homeownership, with or without a mortgage, is down at 66%. When compared to previous reports, we can see a decrease in household ownership, given that in 2015, 68% of households owned their homes – and in 1998, this number was up at 70%.

    If household ownership is down, then that must mean that another index is up, correct? Absolutely! Those same ABS reports show an increase in renting. Taking those same readings, we find that in 1998, renting was down at 27%. In 2015, it went up to 30%. Currently, renting in Australia represents 32% of Australian households – and that number tends to keep increasing

  • Granny Flats represent a win-win scenario for everyone

    If you already own your home, regardless of mortgage, you could be sitting on a pot of gold without even knowing it. According to a combined analysis by Archistar and CoreLogic, building a granny flat on your premises can increase your weekly rental profits by up to 27%. Their last report found that over half a million Australian households could build a granny flat of at least 60 square meters on their terrains.

    Those of you looking for affordable housing can rest easily. Granny flats typically rent for much less than standard apartments, and you won’t even have to leave your desired area. However, don’t let the name confuse you. Although they’re preferred by senior citizens, granny flats are an excellent alternative for young married couples, first-time homebuyers, and young investors, as well.

    What does it mean for the economy, though? Well, if you hop on this wagon, you could be a part of the booming housing development industry. According to Robert Coorey, Archistar cofounder, banking on granny flats can be worth up to $87.5 billion to the construction and development industry.

Granny Flats in New South Wales

Why Build One?

Here’s why:

According to the latest 2018 Housing Industry Association report, New South Wales is currently Australia’s granny flat capital. With more than 6,000 units built, they boast more than double the number found in the runner-up state, Queensland. From that same report, we can see that Victoria is sunk at the bottom position, with just a bit more than 150 units built.

What is the reason behind these numbers? Well, the most relevant player in this housing game is called regulation. In New South Wales, housing regulation is much more flexible than in other states. For example, if your residence meets some specific requirements, you can apply for a complying development certificate. There’s no need to lodge a development application, making it easier and quicker to build a granny flat.

Regulatory issues are not the only factor involved, of course. Larger land sizes and multiculturalism are also huge variables that make the New South Wales state so prone to the granny flat success. In NSW, you can find the largest new lot sizes in the entire country. Also, being home to so many different cultures for whom the multi-family living concept is so common, the idea of a granny flat will appeal to a broader target market. All these factors make it that much faster to find a return on your investment while having a positive social and economic impact on your area.

  • Who is s Granny Flat Ideal For?

    Like we said before, granny flats are not just for our beloved golden-year family members. They represent affordable opportunities for all generations to live both comfortably and independently, without having to become estranged from their family ties.

  • Young Married Couples

    As long as we’re being honest, we all know that owning your first house is not as easy as it was over the past decades. After you and your spouse have said your vows, you might find it hard to find affordable housing close to the areas of your choosing. Apartment rentals are rapidly increasing, and you might have to settle for a tiny shoebox flat that will fit within your budget.

    Unless, of course, you’re looking for a granny flat. You can save a lot of money with this housing alternative since granny flats are considerably cheaper than regular apartments. You also have the advantage of sharing the same yard as the main building, making it ideal for raising your small children or have pets.

  • Established Families Looking for an Investment Opportunity

    For households that already own their houses, granny flats represent an excellent investment opportunity for the years to come. Depending on size and amenities, a granny flat might cost right under a couple hundred of thousands to build. The building adds value to your home, making it possible to earn rental profits of up to 27% more per week.

    In Newcastle, thanks to the multicultural population, it’s also an attractive opportunity to expand horizons and learn more about these cultures. Granny flats are independent and detached buildings, but there will always be room for some socialization.

  • Retirees Looking to Save Some Money (And Help Their Kids)

    Recent studies show that 1 out of 4 Australians feel uneasy when thinking about their retirements. It comes as no surprise, given that on average, retirement costs about $300,000 to $400,000. Now more than ever, retirees are choosing granny flats to save money themselves, while helping their children make an additional income.

    Money is not everything, though. By choosing to live in a granny flat, you and your family can experience the best that these golden years have to offer. Enjoy some quality time together with your kids without losing your hard-fought independence and personal space. Financially speaking, is a win-win scenario for everyone.

    After building your granny flat, your lot becomes more valued. How so? You can expect an increase of about 30% of the land value, not to mention the 27% profit margin per week this building will give you. Considering that the investment is minimal, it’s safe to consider granny flats as literal pots of gold.

  • It’s Profitable

    After your granny flat is ready, you can expect a rental income similar to that of an Airbnb unit. Granted, it’s less than a commercial apartment, but so has been your building investment. With a granny flat, your ROI comes around much faster than with ordinary real estate.

  • It Serves as Added Value

    After building your granny flat, your lot becomes more valued. How so? You can expect an increase of about 30% of the land value, not to mention the 27% profit margin per week this building will give you. Considering that the investment is minimal, it’s safe to consider granny flats as literal pots of gold.

  • It Serves as a Home Office

    After the most recent pandemic outbreak of the new COVID-19 from earlier this year, several business owners and independent professionals have had to shut doors to their offices and practices. If you’re working remotely, you must know for sure that being at home while taking care of business can bring you mixed feelings.

    Several studies have shown that if you want to become successful while working at the home office, you need a dedicated space you can call yours. A granny flat can serve as a detached office, within your house. You will be able to focus entirely on business, all while being a few steps away from the comfort of your own home.

  • It Enables You to Take Care of Your Elderly Parents

    The original purpose of granny flats is to provide a safe space for your elderly parents to live in, while you take care of them. At Grouse House Homes, we understand this prerogative and we can deliver a fitting solution for you and your loved ones.

  • It Helps your Children to Prepare Better for Their Lives

    Times are changing, and the younger generation is living with their parents for longer periods. Of course, with age comes a sense of responsibility and independence. After your kids have graduated from college or right after they get married, they will need stability and comfort before they can face the brave new world.

    A granny flat will enable them to save some money, learn all the tricks about what it means to live by themselves, while still having you around when the rough times come.

  • It Serves as a Crafts Room or Hobby Space

    Just like with people working in the home office, craftsmen and artists need a personal space, an atelier, to work their magic. Especially if you have small children, a granny flat can serve as a personal studio, away from the noise and the distractions of your daily routine. Because we all know you can’t really combine those two scenarios and still be a successful artist.
