10 Ways to Take Your Backyard to the Next Level
A pond for ornamental Koi fish can be customized, and illuminated with energy-efficient LED lights, which are also available in a variety of colors. (Today, you can even program them to turn on and off with your smart phone!) A small waterfall and rock outcroppings can also be added, and the water can efficiently recirculate. A three-foot-deep Koi pond, roughly 300 square feet and built from concrete, might cost $40,000; going with a thick rubber liner will lower the cost to between $10,000 and $15,000.
