If you can, you should build about 3 or 4 of them. It all depends on how much you play. If you play alot, then you will need more than one as the grass becomes worn. I don't really know how to do it, but I would level some land out, plant whatever grass that is used, water it, cut it short then get some chalk and paint the lines. At a country club near my house they have a few grass courts. S&V domination...I can beat all of my friends on grass!
