The Winchester House - 18

In the final show, Steve checks out the new garage storage system, including diamond-plated cabinets, toolboxes, and adaptable ""gear walls."" Window treatment specialist Kevin Murphy shows Steve the custom shades and drapes ordered by mail, and A/V expert Mike Smith shows him an ""out of the box"" media room solution that won't break the bank. Roger literally lays the groundwork for a lush new lawn next spring with a three-layer customizable grass seed mat. Norm and coppersmith Larry Stearns install a TOH weathervane atop the finished garage, while Steve test-drives some high-tech toys for the new home office. Moments before the wrap party begins, interior designer Carolina Tress-Balsbaugh reveals her multi-textured interior design for the sunroom, living room and dining room.
