Ahmed and the twins get a helping hand from everyone's favorite Australian builder and Wasted Spaces guru, Karl Champley. As the floors go down throughout the house, including a tiled entryway and hardwoods in all the rooms, Karl makes use of the less visible areas. He outfits the pantry, handles some outdoor storage for the hot tub steps, and even finds a home for a hidden safe. It's all about flooring — and storing.
