Reinvigorate Your Property or Build Fresh

At KM Custom Homes, we provide good old fashioned service with our collaborative, tailored approach.  We believe every home should reflect the unique lifestyle and taste of its owners. With a custom-built home, you control every detail, creating spaces that maximise comfort and style. Our custom homes are flexible, designed to adapt with your needs and include sustainable, energy-efficient options that add lasting value.


For those who love their current home but want an update, our renovation services can present the perfect solution. From modernising kitchens and bathrooms to refreshing living areas, renovations enhance both functionality and property value without the need to move. And when space is the priority, our extensions provide room to grow while maintaining the look and feel of your home. Whether it’s expanding living areas or adding new bedrooms or alfresco spaces, we ensure each extension blends seamlessly with your existing design.


We proudly serve clients throughout Melbourne, including Mount Eliza, Mornington Peninsula, Frankston South, Mount Martha, Mornington and Red Hill.

CREATING AN AWARD WINNING HOME

By collaborating closely with both the client and architect, we successfully brought to life an award-winning home in a breathtaking location. While the design exudes a sleek and minimalist aesthetic, the construction process was anything but simple. This project presented significant technical challenges, particularly in executing the intricate curves and bold cantilevers that define its striking form. Through expert craftsmanship and innovative problem-solving, we achieved a seamless blend of elegance and engineering, resulting in a truly exceptional home.

Who We Are

At KM Custom Homes, we design and build homes that feel calm, intentional, and uniquely yours. Every space is thoughtfully crafted to not just look beautiful but also reflect your lifestyle with balance and purpose.

Based in Mount Eliza and working across the Mornington Peninsula, we specialise in bespoke architectural builds, including new homes, renovations, and extensions. Our approach is measured and considered, giving each project the time and care it deserves.


Led by builder Karl Melkus and backed by over 30 years of experience, our team delivers lasting quality and personalised service. We take on only a select number of projects each year to maintain the high standards we’re known for. Nothing we build is ever mass-produced — every detail is intentional.



We understand that a home is more than a structure. It’s a reflection of your needs, taste, and vision. That’s why we guide you through the entire process — from initial consultation to permits and construction — ensuring every element aligns with your design, goals, and budget.
