Abstract A recreational facility is described incorporating a plurality of tennis courts positioned in an array with the center lines or longitudinal axes of the courts emanating from a common point. The center lines of adjacent courts are positioned at an angle such that the boundary lines of the second halves of the courts overlap. An automatic ball-throwing machine is positioned in the second half of each of the courts to propel tennis balls to the first half; the second half of each of the courts is graded and provided with a trough to urge the balls to return to the machine. The recreational facility is also provided with a service area which is surround by the tennis courts; the second half of each tennis court is abutting the service area to provide the boundary of the service area.
