  • 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 a house extension, 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.

    You have options to increase your living space without completely redesigning your house. My residential building design services can help you with everything from redesigning your living space to an open plan for improved flow, to creating that extra bathroom, laundry and carport, to raising and building under to suit your growing family.

    I’ll collaborate with you to craft a tailored floor plan layout that not only adds square footage but truly enhances how you live. The end result of your house extension will be a home you and your family will love for years.

    Extending your home may involve navigating various building codes and restrictions.

    Here is some suggested reading if you are interested in learning more about the history and architectural features of Queenslander homes:

    Bulkhead – The part of the wall above an opening. It might be used to hide a beam. Or it might be more decorative and used to separate different spaces whilst still providing an open plan.

    Load bearing wall – A wall that supports the weight from above. To remove this type of wall, an engineer is required to specify a beam to suit. This beam may be located below the ceiling and therefore be visible.

    Pitching point – The pitching point is where the roof comes down and meets the wall. The weight of the roof therefore is loaded on that wall. This wall would then be a load bearing wall. This is important to understand, in Queenslanders in particular, due to their articulated roofs.

    A specification document lists the fixtures and finishes specified for the build. Builders love being provided with a colour specification. Having this document before the build commences means a smoother process as the builders have all the information upfront.

    Yes. If you have your own engineer or are a surveyor, or would like to organise your own external consultants, then I am able to provide a tailored quote to suit your individual requirements.

    Nearly 20 years in the building industry! I started my first real job as a draftee at a project homes company, where I learned a hell of a lot about construction and processes, but I also learned that I would rather talk to the clients myself so I can understand what they are trying to achieve rather than guessing via 3rd person paperwork.

    10 years later I upgraded my education from a diploma to a degree. Whilst on maternity leave I took a leap and became a licensed building designer.
