Text in English and German. This monograph describes the construction of reality through the cognitive subject, and, associated with this, potential ways for producing space. The book studies methods for exposing, through indeterminacy, the definition of space to a larger field of possibility within personal interpretation, and thus virtually de-bordering space. Against a historical background of past attempts to de-border space visually, new possible ways of indeterminately defining space through the modulation of light are shown. The analysis of various modulation phenomena is illustrated with references to works of art, and the phenomena are studied with a view to integrating them in the actual production of space. The modulation of light has the potential of creating diffuse and ambivalent characteristics on space-defining surfaces. This fuzziness offers an opportunity for a freer interpretation of spatial definition and thus also for de-bordering space due to the process of perception. New materials and technologies can be used to create spatial worlds that open up genuine, hitherto unknown realms of cognition and experience. Based on multilayered, ambiguous spatial situations, according to the author, new open spaces of perception are possible and thus an expansion of human consciousness as well with respect to the world around us.

Situated at the intersection of public realm, urban design and site specific art, Martha Schwartz Partners has over 35 years of experience designing and implementing installations, gardens, civic plazas, parks, institutional landscapes, corporate headquarters, master plans, and urban regeneration projects. MSP works with city leaders, planners and builders at a strategic level so as to advocate for the inclusion of the public landscape as a means to achieve environmental, economic and social sustainability. With offices in London, New York and Shanghai, the practice is engaged in projects and consultation around the globe and has to date worked on projects in over 20 countries and five continents. This monograph is the first publication to document 55 built projects and a selection of master plans by this internationally acclaimed practice.
