Melbourne's Portable Building Manufacturer

POMO Modular is a Melbourne-based manufacturer of portable buildings and relocatable granny flats. We build using BlueScope TRUECORE® steel frames—the same structural steel used in commercial construction—rolled and formed in our own factory. This vertical integration means we control quality and cost: no imported frames, no middlemen markup, and no EPS foam insulation. Every building ships with full engineering documentation for Victorian building permits, including NatHERS 7.1-star energy assessment and structural engineering certificates signed by registered engineers. We deliver lockup-stage buildings to Victoria, Tasmania, South Australia, and New South Wales, with standard builds ready in approximately 21 days from order confirmation.

Why Choose POMO for Your Portable Building?

We manufacture portable buildings differently. While most suppliers import pre-fabricated steel frames from overseas or use cheap EPS foam panels, we roll BlueScope TRUECORE® steel in our own Melbourne factory. This Australian-made approach means:

  • No imported materials — 100% Australian steel from BlueScope
  • No EPS foam — We don't use expanded polystyrene insulation
  • No middlemen — Direct from our factory to your property
  • 50-year TRUECORE steel warranty — BlueScope warranty on the steel frame (steel only)

Every POMO building ships with complete engineering documentation: structural certificates signed by registered engineers, NatHERS 7.1-star energy assessment, and Colorbond roofing compliance certificates. This documentation package is everything your council needs for building permit approval.
