I live in the tennis wasteland of the world and am trying to get tennis going here. A fair number of people play recreationally in the summer but there are no indoor courts within 50 miles - the closest are over a mountain pass that can be treacherous in the winter. So, I have thought about building some indoor courts. One way to make them profitable (or at least break even) would be to make them useable for other activities - volleyball, soccer and basketball come to mind. Does anyone have any suggestions about court surfaces that would work? I remember back in my early days of playing (the 1970s), many indoor clubs had a carpet surface. It was really fast but I could see it being useable for soccer, basketball and volleyball. Does anyone know of a source for that surface?
