text: i want to build an outdoor basketball court and want a how to guide? i have a space of 17 feet by 36 feet to build a court for my 12 year old son.  the backyard is not exactly level.  it slants downward about 1 or 2 degrees from where we would like to locate the basket.  i would like to know how much the concrete would cost to cover the 17x36 feet dimensions (maybe about 2 inches thick) and what is needed to create a foundation and how to level the ground. if you just want a court to shoot around and have some fun with your 12 year old son, the slant surface shouldn't be too much of a problem.  i would say the most important thing is getting the backboard/hoop set up.  i would recommend an adjustable height style hoop.  as for the surface, put the hoop up at the lowest level.  the 17x36 concrete cement can be purchased at home depot or any similar store.  i would lay just a thin layer of cement, not too deep into the grount and let it dry.  best of luck.
