An 80,000 lb. concrete monolith portion of a home developed by Jacksonville, Florida-based Montenero U. S. has been installed in Moore, Oklahoma, the site of a devastating tornado May 20, 2013. Comprising almost a third of the 1,885 square-foot house’s structural support, newsok.com informs MHProNews.com the shell will provide an EF5 tornado and hurricane-resistant space in the otherwise normal-looking home. Jay London, builder and founder of Jay London Homes LLC in Moore, says the nearly 600 square-feet shell, manufactured with openings for impact-resistant windows and hurricane shutters, includes two bedrooms and a bath. The exterior siding, interior drywall and traditional roofline hides what London calls “one big safe room.”
