Growing up, I lived in places which would make that look like the lap of luxury, so yeah, I could live in it. My house is bigger (24x 44, including the 8x24 addition) but could be described as rustic. Such a build could be constructed of foam core panels, blocks, or could be built as a timber frame with whatever infill is desired; short logs, lightweight frame, whatever. Most people today, can't fit their ego into a small house; let alone their possessions. GD
