This 3,000-square-foot, ranch-style welcome center is a prototype whose earth-savvy building practices earned it a platinum LEED ranking from the U.S. Green Building Council. Sustainable features include salvaged construction-site stone for the fireplace and chimney, and ceiling trusses that were reconstructed from a dismantled pier, along with wheat-board cabinets, cork kitchen flooring, and sunflower husk countertops. More than 90 percent of construction debris was separated at the site and recycled.
