Granny Flat

What Is a Granny Flat?

A granny flat is a self-contained secondary dwelling built on the same property as an existing home. Internationally, it is also known as an accessory dwelling unit (ADU).

It typically includes a private entrance, kitchen, bathroom, sleeping area and living space. It can be used for ageing parents, adult children, guests, home offices or rental purposes where permitted.

GSMOD granny flats are manufactured in a controlled factory environment using a permanent steel modular system, helping reduce on-site construction and improve quality control. Each project requires confirmation of local approvals, engineering and certification.
