pattern language: unprogrammed space

I was thinking about the wardrobe in our bedroom the other day, and wondered if the preference for storage furniture over storage architecture (closets) points to any truths about the way Thai people think about space. Generally, it seems that traditional (excepting temple) spaces are multi-functional, and many times portable. (think houseboats, floating houses, pre-fab buildings on stilts.) Electrical and plumbing is often exposed, and easily modified---creating spaces perfectly suited for today's needs, but not "set in stone." Another thought on this: I think a lot of Thai people are more likely to bring the dinner table into their favorite room just for a meal, than have a separate space just for dining.
