Why Choose Extensions Unlimited for Your Home Renovation?

For 25 years, the building team behind Extensions Unlimited has endeavoured to provide high-quality house renovations across Melbourne – particularly in the south east suburbs. With so many years of experience using renovations and extensions to help clients turn their family home into the home of their dreams, Extensions Unlimited will guide you through the entire process of adding a 2nd floor from design through to handover. You don’t have to worry about a thing.

Our vision is to deliver cost-effective and highly efficient house renovation and extension services for property owners in Melbourne and surrounding areas. We aim to be completely transparent in our communications, so when we tell you the bathroom renovation cost, that is what you will pay − no hidden charges are added to the cost unless we discuss it with you first.
