“In the past, the square footage of a home was probably the single biggest factor in determining its level of comfort and livability. Today, technology and a growing trend toward informality make the size of the home less important. You can get to the same level of livability at lower cost by putting your money into room design, sound proofing, and technology. My best guess is that a technology cave could achieve the same level of livability as a McMansion, at a quarter of the price.

I predict that someday you’ll see a technology company such as Apple or Google get into the residential technology cave business. The traditional residential construction industry will never embrace smaller homes with better technology. The change will have to come from another industry.”
