The SMALLHOME-70M2 is a seventy square metre (total footprint) two-bedroom home which includes a large covered deck/veranda, an open lounge/dining/kitchen area, and a separate bathroom.   With an internal floor area of 46m² it fits within the "granny flat" definition of sixty-square-metre maximum floor area (for dual occupancy dwellings on suitably sized blocks of land) which in most Australian states doesn't include external decking in the calculation.  The total materials and components cost of the SMALLHOME-70M2, including finishes and fixtures, will be around AUD$60,000 (based on current Bunnings retail prices) and it can be built in around five weeks by a small team of carpenters.
