A reconfigurable office partition includes a movable panel with a rigid frame, a core panel mounted therein, and at least one cover panel detachably mounted on the frame and enclosing an associated portion thereof. The frame has at least one vertical stile with first and second channels that extend longitudinally therealong and are shaped to receive utilities therein through outwardly opening sides. The outwardly opening sides of the channels are juxtaposed in opposite directions to facilitate routing utilities along both faces of the panel. A variable height frame support may be positioned between the top of the panel and the building ceiling for floor-to-ceiling applications.
