Need room to grow?
At Katana, we understand that life changes—and often, your home needs to grow with you. Our expertly delivered Home Extensions offer the space and functionality your family needs, without leaving the place you love. Whether it’s extra room to entertain, unwind, or raise a growing family, we help you reimagine what’s possible.
With over 45 years of combined experience, our team creates extensions that blend seamlessly with your existing home—whether traditional or contemporary in style.
Understanding your lifestyle
We design and construct custom home extensions across Melbourne, from ground floor additions to second storey builds. Every home is different, so we tailor each design to suit your lifestyle, space, and personal taste. Our collaborative process ensures your ideas are brought to life with precision and care.
Ground floor extensions
A well-planned ground floor extension can completely transform your home. By reworking existing layouts and opening up internal spaces, we create functional living zones that connect beautifully to outdoor entertaining areas. The result is a more spacious, practical home filled with natural light and improved flow.
Second storey extensions
A second storey extension adds a whole new level of livability without reducing your backyard. Whether you need more bedrooms, a kids’ retreat, or a private space for parents, we design upper levels that match your home’s original character while enhancing function and value.
