Granny Flat Experts

A granny flat is a self-contained living space, usually built on the same property as an existing home, ideal for family, guests, or rental income. CMM Builders provides professional granny flat construction across North Brisbane, Moreton Bay, and surrounding areas, delivering functional designs and quality builds.



A granny flat becomes necessary when homeowners need extra living space for elderly relatives, adult children, or rental opportunities. Many families in North Lakes, Redcliffe, and Caboolture choose granny flats to increase property value while keeping loved ones close.

Building a granny flat requires careful planning, approvals, and coordination with licensed trades. CMM Builders manages the full process, including engineering, plumbing, electrical work, and finishes, ensuring your granny flat is built safely, efficiently, and to a high standard.
