  • Why Astra F20?

    Architectural Minimalism

    The flat roof design offers a more "built-in" look compared to traditional pitched-roof prefabs, ideal for high-end ADUs or boutique cabins.

    Enhanced Logistics

    Optimized for global transport, our flat-roof design ensures easier stackability and fits 2 full units in a standard 40HQ container.

    Rugged Resilience

    Hot-galvanized steel frame with electrostatic white powder coating provides a 20+ year lifespan with minimal maintenance.
