Border Conditions is an academic and hypothetical project by Manuel Torres, Dimitrie Stefanescun that utilizes parametric folding to achieve complex form in an urban housing project for Utrecht, Netherlands. This project, ‘embodies a virtual study of the process of folding with its conjectural actions (re-folding, unfolding);’ creating architecture from a meta-analysis of the folding technique.  
Here, form is achieved through the interrelation and formalization of different variables, labeled as: ‘horizontal fragmentation,’ ‘proportion blurring,’ ‘vertical fragmentation,’ and ‘plane abstraction.’ These variables are mapped across the site to create points of reference which are then extrapolated into lines and planes. These planes, when merged with circulation routes, generate form and space. The resulting spaces are then further manipulated by varying the points of connections between planes with regards to connection degree, length, and overall number of connections. This form is then deconstructed; unfolded, laid out, and related to the urban site. 
This project focuses on the digital manifestations- parametric form- that result from an analog process- folding and unfolding- and hows these opposing approaches to making can result in varied architectural space. Through  a process of iteration dependent of parametric values, the designers are able to achieve an architectural complexity based on physical variables that is then overlayed on an existing urban fabric.
