The design of your granny flat can be fully tailored to your needs.


Whether you’re building for family use, rental income, or extra space, we work with you to create a layout that fits your property and your goals. From compact one-bedroom units to larger two-bedroom designs, there is flexibility in both size and configuration.

The final price depends on several factors, including size, layout, materials, and level of finishes. Site conditions and access can also affect the overall cost.

In terms of cost, most granny flat projects typically range between $250,000 and $300,000.

At AMGCUBE, we focus on providing clear pricing and practical solutions — helping you balance budget, functionality, and long-term value.

Our goal is not just to build, but to help you make the right decision for your situation.
