Ferrous slate from Brazil, which was supplied and installed by Diniz Design of Baton Rouge, LA, was used as 16- x 16-inch tiles for the interior flooring throughout the building. A total of 4,300 square feet of slate was used for the first floor, which includes the lunchroom, breakroom, vestibules, waiting room, stair corridor, elevator, bathroom walls (wainscots), baseboard, handicapped restroom and mop rooms.
The stone was also used for the design of the porch and the plaza which leads into the building, tying together the interior and the exterior, according to Harvey. Slate tiles measuring 12 x 12 inches were used for the front entrance of the porch, with larger 24- x 24-inch tiles for the entrance walkways. "The slate used for the plaza ties into the concrete sidewalk, which brings you into the space," said Harvey. A total of 1,600 square feet of slate was used for the porch and the walkways.
