At Katana, we take the time to truly understand your goals and how you live in your home.

From there, we explore tailored ideas for your home extension or renovation and guide you through our specialist Design and Construct process.

We also provide a clear, early-stage budget estimate based on your needs and vision.

Once you’re happy to move forward, we return to your home to take detailed measurements.

These measurements allow us to develop accurate 3D concept drawings tailored to your project.

This is the exciting moment where your home extension or renovation vision starts to take shape — and you’ll see your ideas come to life on paper for the first time.

It’s a key step in our Design and Construct process and sets the foundation for a truly customised result.

Once you’re happy with the ideas we’ve developed together, our team visits your site to prepare a detailed project specification.

This allows us to provide a clear, fixed price for your home extension or renovation.

At this stage, you’re welcome to get creatively involved — helping shape the finer details and bringing your dream home design to life.

It’s a collaborative step in our Design and Construct process that ensures your vision is fully integrated into the final plan.

Once we’ve finalised your custom design, specifications, and fixed price, we take care of all the required planning and building permits.

As your trusted home extension builder in Melbourne, Katana handles all the behind-the-scenes work — including town planning approvals — to keep your project on track.

With permits in place and your building contract signed, we’re ready to bring your home renovation or extension to life with a smooth, professional build.

With Katana’s tailored project management systems, your build is guided smoothly from start to finish by your dedicated Project Manager.

Our approach is designed specifically around your custom home extension or renovation, ensuring efficiency, clarity, and care every step of the way.

We work exclusively with trusted, high-quality tradespeople who share our commitment to craftsmanship and professionalism.

As your chosen extension builder in Melbourne, we prioritise your project and treat your home with the respect it deserves.

At Katana, we conduct regular site inspections to keep your home safe and clean throughout your home extension or renovation.

We provide weekly project updates and clear timelines to keep you fully informed.

We also encourage regular site meetings, so you always know what’s happening inside your home.

We believe the journey is just as important as the finished result — and sharing that journey together delivers the best outcomes for your Melbourne home renovation project.
