“After researching a number of granny flat builders on the Central Coast and Newcastle, Acrow Investments were flexible with our requests and were able to negotiate professionally about inclusions and price. Being from Sydney we wanted the construction process to be quick and easy as we were unable to travel often.”



“I would highly recommend the Acrow team, who have been professional, easy to deal with and offered help throughout the whole process above and beyond just building a Granny Flat. Thanks to all the team.”

“Very professional team, delivered on time and on budget, which is a rarity in the building industry. It took approximately 3 months from start to finish to build the granny flat under difficult circumstances. They only use quality appliances and materials. Highly recommended, I will definitely use Acrow again as it is a company you can trust.”

Why invest in Lake Macquarie?

A hidden investors gem, Lake Macquarie is becoming one of NSW hottest destinations and fastest growing regions (in fact, the third largest regional city in NSW by population). For investors, choosing Lake Macquarie over Sydney is a no-brainer. Property prices in Sydney are increasingly becoming unaffordable, but Lake Macquarie offers the chance of generating an additional source of income with potential 10-15% ROI* (and growing).

Lake Macquarie has a thriving, diverse community – over 20,000 residents were born overseas. It is anticipated there will be a demand for 13,500 new dwellings by 2036 as the city’s population grows by an additional 28,000 people. 

A short 10 minute journey to Newcastle, and 35 minutes to the Hunter Valley wine region, Lake Macquarie is a perfect blend of city, regional and beach lifestyle. With over 12,000 active businesses and 1.3 million international and domestic tourists visiting every year, Lake Macquarie is the perfect place to invest.

Have a question?

We have been leading the local building industry for many years and our experts get asked questions every day. See below some of our most frequently asked questions. Have some more questions? Feel free to get in touch with one of our experts today!

What is Acrow Investments’ experience in building granny flats in the Lake Macquarie area?

We were among the first to build granny flats during the Lake Macquarie region’s recent growth surge. It’s just part of our 20-year career building granny flats across the area, including Morisset, Cooranbong and Bonnels Bay, to name a few. As trusted local builders, Acrow Investments understands how the local councils regulate and govern new granny flats and home projects in this region. We combine our knowledge of the local landscape and site conditions with our build expertise to provide you with a free site inspection and no-obligation quote.

How much does it cost to build a granny flat in the Lake Macquarie area?

Our standard two-bedroom granny flat in the Lake Macquarie area – from start to turn-key – starts at $99,000 (inc. GST). We provide premium inclusions in our standard builds; however, some additional costs will apply. These can include external works, council approval fees and land prep. The important factors here are your suburb, size of block and site conditions. Contact us to arrange a consultation where we can conduct a free site inspection and provide an obligation-free quote.

What is the average rental return of a granny flat in the Lake Macquarie area?

If you’re adding an Acrow Investments granny flat to your property as an investment, you’ll value our free rental return report. As a guideline, the average weekly rent for granny flats in the Lake Macquarie area can range from $350 to $450. If you’re planning to finance your build, a standard interest-only mortgage repayment will return gross profit averages around $250 to $300 per week. To obtain a free rental report of your own, give us a call to arrange your no-cost, no-obligation site inspection and quote.

Do I need planning permission to build a granny flat in the Lake Macquarie region?

With the State Environmental Planning Policy (SEPP) covering granny flat builds in the Lake Macquarie area, your project will not require council approval or planning permission. Still, general NSW zoning rules and legislation do put controls on front and rear setback requirements: your new granny flat build must satisfy these. The good news is that with almost 20 years of experience, we’re well across all the conditions and contingencies – so, give us a call to discuss your project. No obligation, just information.
