tailored granny flat solutions

a versatile way to increase your living space

If you have the land size to do it, granny flats are a fantastic way to accommodate additional family members for long-term stays while still allowing you to live separately. This solution is perfect for interstate guests, older parents, or grown children who haven’t yet moved out. 

Granny flats can also provide the extra space needed for new hobbies or side hustles, giving you room to store supplies and expand your projects.

Three Stems offer custom-designed granny flat plans that are tailored to your block size and desired use. Get in touch to explore your possibilities!

  • About Three Stems

    Hi there, I’m Stella! I’m an experienced residential building designer with a passion for helping Brisbane families make the most of their homes.

    If you’re considering extending your living space via a granny flat, I’m here to guide you every step of the way, ensuring the residential building design process is smooth, enjoyable, and tailored to your needs.

    Building a granny flat can be an excellent way to increase your property’s worth, and I’ll help you do just that.

    In most cases, there is no need for an architect and a draftsperson to draw up your granny flat designs – I can offer compliant building plans tailored to your lifestyle and design preferences.

    If you’re also looking to extend, raise and build under or renovate your main dwelling, I can assist with that too!

    The initial draft will be sent through to you with options, based on the onsite consultation.

    The first plan will provide the layout as discussed and an alternative option as applicable. You then have 2 opportunities to make changes to your selected layout.

    Sometimes. This will depend on who owns the easement, and what the easement is for. The certifier will do an application either to the Brisbane or Ipswich City Council, or to Urban Utilities. To find out who owns the easement, a titles search maybe required, which for Queensland properties can be done at this link:  https://www.titlesqld.com.au/title-searches/ 

    Absolutely! As part of the pre-site package, a 90-minute onsite colour consultation is included free of charge with my Interior Designer Stephanie from Margaux Interiors. If you need further support we can arrange a price for a full specification document to be provided. 

    Yes! In the first revision I generally provide 2 floor plan options, and sometimes a few different alternative layouts for say the bathroom or kitchen. 

    The process will get your ideas from your head, onto building design plans, which are then approved by a certifier, meaning you end up with plans that are ready to hand to a builder for construction.

    In short, generally 3-4 months from our first site visit to gaining approvals for the build.

    The timeline depends on factors like how quickly you make decisions, as well as any site-specific applications or restrictions, such as town planning, relaxations, and BOS applications. Here’s a typical timeline:

    • Surveyor: Provides the survey within 2 weeks of the initial site visit.

    Once I receive her plans and conduct my site measure, whichever comes last,

    • First Draft: Sent within 2 weeks after receiving the survey plans and completing the site measure.
    • Subsequent Drafts: Turnaround is significantly quicker.
    • Engineer: Takes 2 weeks to complete their part.
    • Final Plans: Provided within 1 week after the engineer’s work is done.
    • Builder Contract: Now is the time to get your builder to provide the contract.
    • Certifier Approval: Takes up to 1 month, depending on the involved applications.
