Just redid the deck and made it bigger and of Trex. Planning an attached patio with pond. See attached pics. Each square on the graph paper is two feet. Pond went from 12x5 to 12x8 (as shown in pic). Thinking of interesting to 13x9. Formal rectangular with water coming from centerof far 13 ft side towards house. Planning central Island to hold my metal Buddha in summer. Not sure if I will have fish but want to have that option available in future. Any thoughts?
