Just a General Question Balloon Vs. Platform Construction
balloon framing was the newest/best thing when it replaced post and beam building. however, starting in the 1930's, the combination of more uniform milling techniques, and increasing scarcity of quality length lumber made platform framing much more popular.
my current home is balloon framed, and it does present a few head scratchers every now and then (for someone who has only owned platform framed before this.)
from the standpoint of remodeling/new construction/additions, i would think that platform framing is the way to go.
