This outdoor room looks expensive. but that's just what the homeowner wants you to think. Inexpensive building materials such as gravel, cinder blocks, and pressure-treated wood form the backbone of the design. Tile backboard and salvaged plywood, stained a soft blue and attached to a custom frame, give the tiny yard privacy.
Concrete spheres bring lasting beauty to any garden. Cast a half sphere at a time, using 10-, 12-, or 15-inch-diameter molds. Sandwich two halves to make a round with a spread of mortar holding the pieces together. Dabs of outdoor acrylic paint add a mossy appearance that becomes even more realistic with weather and age.
