re 'drywall on sticks' - not only does this construction technique provide for a huge amount of flexibility in interior layout, it's by far the most earthquake friendly construction for single family homes.

It wouldn't be at all surprising to see a home built with such 'toy' materials require nothing more than some stucco repair and drywall patching, with a brick house right next door literally falling apart.

I realize not every region has earthquakes to worry about, but it is a factor in some areas.
