I have chosen to use solar power, collect rainwater, and use reclaimed wood to lessen the impact of this sculpture on the environment. This sculpture won't use and waste excess water or power, it will only use what naturally comes from the earth.  I would build a base out of wood or concrete and then attach the support pillars. Then use thinner planks to create the roof, and make and attach wooden gutters. I would need to spray the wood with a water treatment so it can withstand being outside, and spray the wooden gutters with a water-repelling coating or insert tubing. The next thing would be to make planters and set them beside the gazebo, and purchase items for a water filtration system--aluminum barrels, piping, a pump, and hoses. The pump would go inside of the barrels on a timer or sensor, and the hosing would attach to barrel and then put on top of planted beds. The hoses should have small holes along the side--big enough to let water out but not too big to maintain pressure. when beds are being planted or if plants are not there wind up the hose and place it on top of the barrel and disable the pump. I would also like to install a tap onto one of the barrels to was fresh picked food
