Radikalno izkoristiti potencial prostora lahko pomeni, da k vsakemu novemu projektantskemu problemu pristopamo s karseda manj vnaprej ustvarjenih predstav in izmed vsega izberemo eno rešitev, ki se bo na koncu izkazala kot pravilna in izjemna. V takšnih primerih resničnost ni nekaj, kar bi kompromitiralo idejo ali jo kontaminiralo z banalnim in vsakdanjim. Namesto tega je samo soočenje med procesom projektiranja in obstoječimi parametri tisto, kar vodi do konceptualnega pojasnjevanja, do intenziviranja in radikaliziranja arhitekturnega koncepta. Hiša z enim zidom Christiana Kereza v Zürich Witikonu kaže, kako lahko nepredvidene okoliščine izhodiščnega projekta odstopijo prostor natančnosti, kako se mora naključno umakniti pred bistvenim.

To radically exploit the potential of space can mean approaching each new design problem with as few preconceptions as possible and wrestling from it the one solution that will finally prove valid and compelling. In such cases, reality is not something that compromises the idea or contaminates it with the banal or everyday. Rather, the very confrontation between the design process and the existing parameters is what leads to conceptual clarification, to the intensification and radicalization of the architectural concept. Christian Kerez’s "House with One Wall" in Zurich’s Witikon district serves to demonstrate how the contingency of an initial design can give way to stringency, how the accidental must yield to the essential.
