The first step is always identifying a good location to install the putting green. If there is a flat spot in your backyard or near your house, that is the best possible location to place your course. The area should be away from trees, fences, rooftops and poles that might interfere with your golf game. It also makes sense to leave enough space around either side of the green for you and other players or neighbours to walk entirely around it without getting too close to any obstacles on the other side of it.
