Last year, nearly 30 percent of new homes in the U.S. had partial or full basements, according to the Census Bureau’s Survey of Construction.
Tsunami House built to withstand high velocity wave action
The lower levels feature a multi-purpose "Flood Room" with breakaway walls
The Tsunami House on a coastal island in Washington State was built by Designs Northwest Architects to withstand conditions not normally faced by a residential property. The main level features a foundation capable of withstanding high velocity tsunami wave action, while the lower levels were built with walls that are able to break away in the event of a storm surge. In order to avoid the full force of a tidal wave, the architects located the main living level nine feet above grade, which left the lower level as a multi-purpose ‘Flood Room.’
