A multi-activity complex incorporates a plurality of activity floors, each of which has an associated playing surface and is selectively movable between a storage position, located below an event staging or activity area, and an in-use position located in the activity area. A system is provided for alternatively shifting the activity floors between the respective storage and in-use positions. The shifting system includes a lift assembly for vertically moving the activity floors into and out of the activity area and a second mechanism for laterally shifti...


A method of alternating the playing surface in an activity area of an multi-activity complex comprising: storing a plurality of activity floors, each of which has an associated playing surface, at vertically spaced intervals below and laterally outwardly of the activity area; providing a lift assembly, having a support structure, below the activity area; sectioning at least one of said plurality of activity floors and storing at least one of said plurality of activity floors in sections; and providing a locking mechanism for fixedly securing the sections...
