How to build a house alone [video]
For those considering something like this, I would recommend the book Working Alone by John Carroll.  He describes how to use clamps, ad-hoc frames and jigs to deal with sheets of plywood, roof beams, etc. without the benefit of a second pair of hands.  Using his techniques I built a stand alone 10x12 storage structure (biggest that does not require a permit) that is the driest building on my property to this day.http://www.raintreeshouse.com/ournewoldhouse/TheStorageShed....
