Granny flats aren’t just for your grandparents anymore.

They have been increasing in popularity in recent years due to their stylish design, quick build times, affordable pricing, and efficient use of available space. On top of the advantages offered in terms of space, these flats represent prime investment opportunities.

With Sydney rental prices consistently leading the country’s averages, using it as a second source of income isn’t just possible, it’s profitable.

What are the benefits?

Any Sydneysider knows the challenges of space in the harbour city. With demand for living spaces at all-time highs and a willing rental market, there’s never been a better time to utilise the excess space in your yard.

If you’re unsure whether your property is suited for this type of structure, consider the following 3 scenarios:

  1. It becomes a rental property and/or long-term investment.
  2. It can be used to house elderly parents and promote healthy living.
  3. It can be used to house your children as they save for their homes.

Of course, the flat can be used to care for family members and also serve as a rental property, to serve as a long-term investment, with the versatility of your own standalone dwelling a hallmark of this affordable construction project.

Accessory Dwelling Units (ADU) is the definition of investing in affordable living.

What are the advantages?

If you’re looking for an investment with almost zero disadvantages, the granny flat comes as close as you’ll find. The benefits include:

  • Low Cost Build
  • Rapid Construction
  • Increase Land Value
  • Brilliant Return on Investment
  • Extra Tenant for Safety & Socialising
  • Usually No Council Approval Required
  • Increased Control Due to Close Proximity
  • Less Complexity & Stress Compared to New Home Builds

Will it add value to my Sydney property?

If you’ve got excess space in your yard, it’s natural to consider ways to utilise it more effectively. If your children have grown up and the backyard is quieter than it used to be, or you’re looking for a way to cultivate a low-maintenance yard, using your unwanted space to build is ideal.

Naturally, you’ll only want to make changes to your property if it benefits you both now and in the future.

That’s where this option offers unrivalled advantages.

Did you know a granny flat can boost a Sydney property’s value by up to 30% and increase rental yields by up to 27%?

Not only are you generating a stream of revenue today, but when it comes time to sell, your land may be worth more too.

Are there any drawbacks to constructing this type of flat in Sydney?

It’s natural to wonder what downsides come with construction, and any builder who tells you there are none is usually an example of the primary disadvantages, and that is the homework required to find the best builder for you.

Working with a reputable builder that offers fully featured flats and is licenced and insured, offers peace of mind from project inception to completion.

However, the wrong builder can leave you in a $100,000 hole, paying for a granny that’s poorly designed, without the right inclusions. You’d then have to pay another $30,000 to $50,000 to fix everything up again, with added stress. If something is not done right initially, it will continually take its toll due to inferior quality - every single day.

It’s also worth noting that you can’t subdivide a property in NSW if it contains this type of flat. If you’re considering subdividing your land in the future, it’s worth speaking to your local construction team to make sure you’re making the right choice.

As a bonus, these buildings offer a built-in income source, so your land is generating revenue even if you can’t subdivide down the line.

Win-win!

Do I need council approval to build this type of flat in NSW?

Let’s be honest, red tape can quickly turn an exciting building project into a nightmare.

Thankfully, in NSW, the Affordable Housing State Environment Planning Policy (SEPP) permits all Sydney homeowners meeting certain criteria to build a flat on their property.

If your property is larger than 450 square metres, has at least 12 metres of road frontage, and is located in a residential zone, then you’re good to go with no paperwork or messy Sydney council loopholes to jump through.

That means you can build a stylish two-bedroom flat in your yard without council approval. You can also convert a garage or another area, and there are many creative ways around planning obstructions.

In less than 14 weeks, you could have a high-quality rental property attached to your current abode.

How much does a granny flat cost to build?

That’s the million dollar question - thankfully, they are much cheaper than that.

We offer a range of designs to suit any living requirements, across 1-bedroom, 2-bedroom and 3-bedroom dwellings. At Bellcast Granny Flats we offer a range of designs to suit any living requirements, across 1-bedroom, 2-bedroom and 3-bedroom dwellings.

The average cost will set you back between $1,600 to $2,000 per square metre, with typical sizes ranging from 35m2 to 45m2 in Sydney.

Compare these prices to a traditional new home build which will set you back between $1,300 to $4,000 per square metre. Not only will you pay more for a traditional home, but the difference in size means your costs are significantly less.

As an added bonus, it can start generating income and paying itself off.

How long does it take to build this type of flat?

Design, form submission, and construction can all be done within 14 weeks (3.5 months).

In contrast, the design, submission, and construction of a regular house can take closer to 12 months, provided you already have a plot of land to build on! The time for completion will also be affected by the size and scope, and whether you opt for a 1, 2, or 3 bedroom.

Factors that impact build time include:

  • Land accessibility (slope or incline)
  • Size of dwelling
  • Sewage placement
  • Stormwater drainage
  • Title restrictions
  • Electrical connections
  • Surrounding neighbour impact

But don’t stress if these sound like massive delays in waiting. These flats are increasingly popular because they’re significantly faster to build than a traditional home which requires vastly more paperwork and council approval, as well as more resources and materials.

We pride ourselves on quick and disruption-free projects, delivering your own modern flat in as little as 14 weeks.
