I totally understand that individuals -- with expert taste and capital to apply to this taste -- will hire great architects to incorporate such Tesla advances into an individual project, but... ... what about the "...80% of the new homes built in the United States..."? Residential Building (Single and Multi-Family) Market. With all due respect - and apologies - to mass-building developers out there... Growing up in Northern Virginia, I've come to have a negative perception of residential developers (Toll Brothers, etc.) ---- believing that they are in it for a quick buck --- building crappy houses with hollow frame doors and use of other crappy materials that will last about 10 years before needing replacement. http://www.nahb.org/en/about-nahb.aspx "The National Association of Home Builders (NAHB) helps its members build communities. Each year, NAHB’s members construct about 80% of the new homes built in the United States, both single-family and multifamily. A federation of more than 700 state and local associations, NAHB represents more than 140,000 members. About one-third are home builders and remodelers. The rest work in closely related specialties such as sales and marketing, housing finance, and manufacturing and supplying building materials. NAHB is member-driven, with more than 2,200 members serving on the association’s board of directors, which elects the Senior Officers and helps set the association’s agenda. Since it was founded in the early 1940s, NAHB has served as the voice of America’s housing industry. We work to ensure that housing is a national priority and that all Americans have access to safe, decent and affordable housing, whether they choose to buy a home or rent. Achieving that goal is increasingly difficult in today’s contentious and unsettled political and financial environment, one in which the concept of homeownership as a national priority is very much under attack. We champion laws and regulations designed to reverse this dangerous course that will drive down the value of the nation’s housing stock, drive up the cost of rental housing, and threaten the economic recovery."
