Her work Dia (2006) consists of a room-like installation, which is accessible from two sides and obstructs the visitor's view into and inside the gallery. The sheetrock - that show obvious traces of the construction process - originates from three of her earlier installations:  Trockenbau. Fassadenraum (1990), GKB 250 (2005) and Trockenbau. Durch 100 x 3,3 (1989). The artist alludes to different layers of time and place entangled in her work, in order to compress the experience of time and space. Her other work, Visum (2006), a hanging installation made of shuttering plywood that swings when touched, creates a vital tension to the first one, and its white colour and vibrant surface texture.
In another work, Dresden, Neustadt (2000), Hörnschemeyer presents twelve platinum prints made in Dresden. These small photographs depict impressions of places in this East German city, which has been left untouched by the reunification process. Even here, the artist explores issues of space and architecture. The brownish platinum prints remind the viewer of sepia tinted photographs from the 19th century, in a strategy to merge various layers of time and place in a single work.  

The title of the show, "Aufenthaltswahrscheinlichkeit", which means ‘probability of finding,' refers to Quantum Physics and describes the probality to find a quantum in a specific region. In the figurative sense Hörnschemeyer expresses this unstable dimension, where something is likely to happen, but not at all certain. With her art she invites us to reconsider our idea of space and to experience a new sense of an architectural landscape.
