Joseph Kennard, Boston
How He Did It: Architect Joseph Kennard wasn't yet sure where he wanted to mount items like wire shelving or a light over the sink when he was renovating his kitchen, so he needed a wall covering that was sturdy and inexpensive and would allow him to experiment. He opted for oriented strand board, a sheathing product with a textured-looking surface that's made from wood chips bound by adhesives. It's typically used beneath finished walls or floors, like plywood is. Using drywall screws, he mounted ½-inch-thick 4-by-8-foot sheets to the walls behind his sink and cooktop. "The material camouflages nail and screw holes, so I can relocate things without having to patch it up," he says.
