The architects Ana Dzokic and Marc Neelen have been collaborating since 2000 as STEALTH.unlimited between Rotterdam and Belgrade on projects concerned with the complexity and inconsistency of today's cities. STEALTH's projects grasp the city as a research laboratory: for instance they have developed a method to read a city and its underlying unauthorized processes such as black markets, illegal construction, etc. and to analyze their inherent potential. Applied as a matrix to other cities, architects and urban planners can use this tool to describe spatial and organisational changes that are taking place. Other projects that STEALTH has developed deal with the dynamics of today's cities through specific interventions in physical spaces, like one in which specifically required ›rooms‹ can be simply cut out of a 1100 m³ grid structure of larger-than-man size cardboard sheets, as well as the design of a research and discussion platform as co-curators of the Dutch Pavilion at the Venice Biennale of Architecture 2008. A central aspect of their work is the constant change in perspective – between visual culture, urban research and spatial interventions up to cultural activism.
