CONSIDERED SPACES. DESIGNED FOR REAL LIFE.
Assembly Interiors design and document enduring residential interiors across Melbourne and the Mornington Peninsula - expertly guiding your project from early ideas through to resolved concepts and build-ready outcomes.
Delivering Your Dream Home, Together
Renovating your home is an exciting journey, but it is also a significant investment of time and money. Whether you are transforming a single room or embarking on a full-scale build, the process introduces complex decisions at every turn, alongside the risk of unexpected challenges and budget strain. And then there’s navigating the myriad of tradespeople involved, which is a job unto itself.
Most renovators find the process overwhelming, not because of one single decision, but due to the hundreds of small choices that weren’t properly planned or resolved early on.
This is where Assembly Interiors steps in. We work closely with you at every stage to bridge the gap between your vision, technical design and final construction. By translating your lifestyle, priorities, and daily routines into a highly considered plan, we create interiors that feel calm, deeply functional, and enduring.
We provide complete clarity on layouts, finishes, and custom joinery, giving you total confidence in your decisions and equipping your builder with precise, construction-ready documentation.
No rushing. No trends for trend’s sake. Just good design, done properly.
From Concept to Completion
We’ll re-design your space then be with you through every step of the process, navigating your budget and approach whilst sourcing the perfect products and finishes.
With you from start to finish, I don’t just design but help support you across the construction stage with the knowledge and experience to help you focus on the end goal being the transformation of your home.
We specialise in kitchens, bathrooms & laundry and custom joinery.
We’ll provide you with mood boards, floorplans, finishes samples, beautiful 3D visualisations and all the technical detail needed, helping you visualise your home like never before.
I help you make confident decisions and manage the design details so you don’t have to.
Designed to scale, our documentation supports your build team visualise the design, allowing them to more accurately quote and build exactly what you wanted.
Your Dreams Visualised
Our designs consider every aspect of your home and lifestyle including the future needs of you and your family.
Every element is purposely selected to create a home that flows and feels like you - where storage works, materials make sense and every decision has a reason behind it.
We are committed to sustainability, and look to incorporate low impact materials and practices, ensuring that our designs are not only aesthetically pleasing but also environmentally responsible.

"The entire process of working with Courtney was seamless, impeccable, collaborative and fun!"
Engaging with Courtney from the beginning completely took decision fatigue and the technical side of the design out of my hands, making our renovation completely manageable. Courtney just "got us" from the very beginning and presented ideas that we would never have thought of. Truly taking our project to the next level and completely tailoring everything for us. We could not recommend Courtney from Assembly Interiors enough if you are thinking of tackling any sized renovation.

"Working with Courtney on our renovation project was the best decision we could have made."
We initially browsed local interior design websites and then found Assembly Interiors. Courtney’s considered designs immediately resonated with us. From the very beginning she listened carefully to our ideas and preferences, responded promptly to any questions and offered creative yet thoughtful suggestions.
Working with Courtney on our renovation project was the best decision we could have made; her detailed design specifications were certainly helpful and appreciated by our carpenter/project manager too, who was able to complete works ahead of schedule. We would highly recommend Courtney to anyone looking to elevate their home.
