The concept for the interior organization of the department store reacts to the ambition to develop a luxurious store on several floors with multiple access points. Therefore the central circulation space is designed as a continuous floor space merging in to one vertical space, the void space. The geometric principle of the vertical void space is the allocation of the elements of vertical circulation around the central zone of the store. In synchronization with the rotation of the façade geometry the sets of escalators spiral upwards to the tenth level and connect with the two basement levels. Through the vertical void customers have clear sight lines, with views of the shop facades and activities around this public void. All public circulation is arranged at different floor levels; the vertical space also acts as a way-finding instrument and as an orientation point.
