Roberta replaced an old chain-link fence with a wooden one and built a gently curved bridge to help define specific areas within the fenced walls, areas inspired by another Asian tradition. "I've followed slightly the feng shui principles of where to put water, wood, earth, fire and metal." The Japanese tea house doors were handcrafted by Roberta and her father, Robert. Other cost-saving measures included hauling in rocks herself and reclaiming old bricks to construct the entryway and bench area. "It has grown to be an enchanting garden. I love the flow I've obtained and the peacefulness that I feel when I'm out here."
