The frame work of this house is almost entirely fabricated using 2x4's. No concrete pillars or larger main beams are utilized here. The pink colour indicates the grade of the timber used which can be H1 to H6. Nails are not often used here because during a severe earthquake all the nails will pop out, causing catastrophic failure and collapse of the house. Staples and galvanized connector plates are used instead of nails, giving the butt joints flexibility and ability to withstand mild earthquakes. For the same reason, double storey houses are not so popular here.
