How much does a granny flat cost?
‘How much does a granny flat
cost?’ asked one of our best friends. ‘Between $180,000 and $260,000 depending on size’, was my well-rehearsed line, thinking it was a fairly obvious answer to an even more obvious question.
She laughed and said, ‘Oh, I thought you were going to say $20,000!!’ then we both laughed – hard!
From there we carried the jovial conversation forward imagining the humble, unapproved abode we could create for her $20,000 perceived budget – dirt floor, straw-thatched roof, beaded doorways, etc. On went the ramblings, and the laughter continued.
This conversation came back to me a few days later as I considered the misconception about what a modern-day granny flat is, and what it truly costs in today’s market; after all, if my BFF has no idea, how could we expect the general public has any idea when they begin the enquiry journey?
BCC Homes
is building quality turnkey homes that are one or two-bedroom, but due to the size, are called granny flats, a bit of an outdated term - we know!
The term ‘Tiny Homes’ has been used and refers to relocatable container homes, so that term doesn’t accurately describe what we do either.
We include ceiling fans, dishwasher, roller blinds, flyscreens, floor coverings – even a separate letterbox if/when required. It’s just like a new traditional home you would build, minus a couple of bedrooms and a garage.
There are some variables to consider with costing, such as whether the property has access to town services or is on septic, engineering requirements, bushfire ratings, and location to the main dwelling. However, here is a rough guide to some pricing:
50m2 - 59m2 granny flat will cost between $165,000 - $195,000
60m2 - 69m2 granny flat will cost between $190,000 - $225,000
70m2 - 80m2 granny flat will cost between $225,000 - $260,000
* Above pricing is based on slab-on-ground construction only.
If you've started collecting quotes for your Granny Flat, you've probably noticed prices can vary by tens of thousands of dollars. So how do you know which quote represents the best value? Here's the thing: not all quotes are built the same way. Two builders can quote the same project, but what they include can be completely different. Understanding these differences is the key to making a confident, informed decision. Let's break down what to look for. 1. Ask for a Detailed Inclusions List Some builders quote only the basic structure, while others include everything from design and approvals to quality finishes and fixtures. The difference can be significant – sometimes $20,000–$40,000 worth of items. Always ask for a detailed inclusions list so you can see exactly what's covered. If something isn't written down, make sure to ask about it. The more detail you have upfront, the easier it is to compare your options fairly. Tip: If something isn’t listed, it’s probably not included. 2. Understand Your Site Conditions Every site is unique. A flat, easily accessible block will have different requirements than one that's sloped or has access challenges. Generic quotes based on "typical conditions" might not reflect your actual situation. At BCC Homes, we never offer a fixed-price quote until Sam has assessed your site. This way, you get an accurate number based on your specific property – giving you confidence in the price from day one. 3. Clarify What's Included in Design and Approvals Some builders charge separately for design work, plan revisions, and approvals, while others include these as part of the process. At BCC Homes, we include design and approvals with 3 plan revisions built in. Understanding what's covered here not only saves you time and potential surprises later but also helps you budget accurately and ensures your design will meet all council, energy efficiency, and bushfire requirements before construction begins. 4. Look at the Builder's Track Record Beyond price, consider the builder's communication style, reviews, and completed projects. A builder who's clear and transparent during the quoting process will give you confidence throughout the entire build. Look for someone who answers your questions thoroughly and helps you understand what to expect. At BCC Homes, we’re happy to walk you through our inclusions and help you compare your quotes line by line, so you know exactly what you’re getting. The Bottom Line The goal isn't necessarily to find the cheapest quote – it's to find the best value. That means working with a builder who's transparent, includes everything you need from the start, and helps you understand every step of the process - no hidden extras, no guesswork. At BCC Homes, we're here to help you understand your quotes and make informed decisions. We're happy to walk you through our inclusions line by line, so you can compare your options with confidence.
