Let us get started. Welcome, and send in your questions. The new ideas presented in your article sound interesting, but aren't people too conservative in their taste and expectations of homes to want something far out of their paradigms. During WWII fantastic innovations in building were invented, or at least widely used for the first time, but they didn't catch on because people frankly didn't want to live in Quonset huts. You raise good questions.
People do tend to be conservative when it comes to the biggest single investment they make.
My own town house is pre-World War II, and mirrors plenty of dreams now outmoded. I certainly would trade it for a Pod or Blob Colonial that would allow living to flow more freely. What you will see are more flexible floor plans and possibly temporary or movable wall systems inside. We've already seen those developments from home builders. I was glad to see discussion of energy efficiency in your article.
