Some houses are designed to be smart. Others have smart designs. An example of the second type of house won an Award of Excellence from the American Institute of Architects.
Located on the shore of Sullivan’s Island off the coast of South Carolina, the award-winning cube-shaped beach house was built to replace one smashed to pieces by Hurricane (飓风) Hugo 10 years ago. In September 1989, Hugo struck South Carolina, killing 18 people and damaging or destroying 36,000 homes in the state.
Before Hugo, many new houses built along South Carolina’s shoreline were poorly constructed, and enforcement of building codes wasn’t strict, according to architect Ray Huff, who created the cleverly-designed beach house. In Hugo’s wake, all new shoreline houses are required to meet stricter, better-enforced codes. The new beach house on Sullivan’s Island should be able to withstand a Category 3 hurricane with peak winds of 179 to 209 kilometers per hour
A. withstand peak winds of about 200 km / hr
B. anchor stronger pilings deep in the sand
C. break huge sea waves into smaller ones
D. prevent water from rushing into the house
