It’s important to remember that while your quote will be as accurate and inclusive as possible, there may be additional costs outside the scope of just building the granny flat that are required to create a functional building on your property. Some extras to consider that may not be included in your quote are:
Before you can build you need to have your site prepared and ready. While it seems a simple idea it often a cost that is overlooked. Be sure to account for any land clearing, removing of trees, rubbish or other obstructions and the removal of any of these.
Any existing structures that stand where you want your granny flat will need to be demolished and removed. While not necessarily part of the cost of your granny flat this will be a cost that needs to be considered to complete the project.
If the preparation of your site and removal of existing structures generates excessive waste, you should account for extra waste removal costs.
These could include developer contributions, water applications and works fees, council administration fees and government levies. Depending on your council area and requirements of your site these can range from $9,000 to over $20,000
Your granny flat will look great, but the yard and surrounding property will be quite bare and take time to recover after clearing and construction. If you’re planning on Gardening, footpaths, garden beds, new lawns, and plants these will be an additional cost beyond your quote.
Don’t overlook the cost of furnishing your granny flat. Backyard Granny’s will deliver a granny flat that is move-in-ready but if you need to bring any new furniture with you to move in this can again be an additional cost to consider before.
It’s frequent for the quote to include items that you may have not considered that will add costs to your quote. These often-necessary additions ensure your Granny Flat is safely built to the highest quality standards and compliant with all local regulations. Some of these unexpected additions include:
The modification of a granny flat design to suit either your selected upgrades or your specific site requirements will require the work of a draftsman and design team. Getting this step right can set expectations and save blowing out in costs down the road. However, there will be a cost associated with detailed design alterations. This will be in addition to standard document preparation and administration for compliance documents and detailed plans.
Your engineering reports may indicate the need for sound or fire compliance. This could look like enclosing under decks or porches, upgraded glazing or upgrades to hardwood that will all add cost to your project. Such adjustments typically cost between $500 and $5000
There is a fee associated with BASIX assessment which is a requirement of any building. This assessment may reveal the need for modifications to your design to accommodate for your site or combination of granny flat selections. These may include extra or higher rated insulation, upgraded glazing or design alteration and can sometimes cost tens of thousands of dollars.
If the transport and delivery of your granny flat materials requires the stopping of traffic your builder will need to submit a traffic management plan to council and pay for traffic management. These costs will vary depending on your property’s location and access but occasionally these costs can become quite substantial up to $10,000 or more.
Your quote will likely include standard connection costs. However, if there are any upgrades to existing connections, or any special site requirements these connections may become more expensive. For example if water requires a pump, or electricity needs to be run a long distance or NBN requires an additional installation. There may be a need to modify the metering on the property, all of these could add costs.
It’s important to discuss with your sales team any special selections you may want to include in your granny flat. While our standard pricing includes everything you need to build a beautiful and functional granny flat you may request additional upgrades that will add to the cost.

Some fees on your quote may appear as provisional or dependant on site circumstance. Check your quote for provisional fees and the conditions they dependant on.
Be sure that your standard inclusions are listed on your quote and there are no surprise omissions or items you expected as inclusions listed as upgrades. This list will be extensive so be thorough to ensure nothing is missing.
When everything goes as expected your quote should be ready in about 2 to 3 days after your initial consultation. While you may see instant quotes or same day quotes from other builders, these could only possibly be an estimate as there are a number of processes involved in building an accurate quote. From contacting councils, to ordering engineering and compliance reports and researching under and over ground connections and adjusting your design and quote accordingly – many of these processes not only take the time of your granny flat builder but rely on the fast communication of third parties.
Don’t be alarmed though if your quote takes longer. Your builder is likely working hard behind the scenes to research and build an thorough and accurate quote that will save you surprises and delays in the long run.
When you build with Backyard Grannys our sales team will take the time to build you a thorough and accurate quote. You can build with confidence knowing your granny flat will be built to your budget.
