Duo-Forma is a series of pre-designed modular buildings developed as part of the Forma Series by Keep Modular. Each product is a complete, self-contained home — built in our Croydon factory and delivered to site as prefabricated modules, ready for installation in a matter of days.

Designed for compact residential lots, Duo-Forma suits a wide range of uses. As a secondary dwelling, it can house extended family, provide independent space for ageing parents or adult children, or generate long-term rental income alongside an existing home.

On larger rural or regional properties, it works equally well as a permanent residence, a caretaker dwelling, or worker accommodation. For those looking to make better use of their land, it offers a practical path to dual occupancy without the complexity of a full custom build.

Whatever the use, every Duo-Forma product delivers the same standard — a resolved, well-finished home with no structural compromises.
