What if we could visit any building, regardless of whether it was ever built? Or, even after it has been demolished? This video and link below focus on a single house — the One Half House — designed by John Hejduk, to resurrect and explore. It uses the program Enscape to walk through the building in order to preserve and distribute the experience of architecture that does not exist in built form. The video offers a timeline to contextualize the role of the house in John Hejduk’s career and work, an analysis of the building, and initial reactions to walking through the building for the first time. In particular, the One Half House was pivotal for thinking about how architectural volumes might relate in space without the ordering device of a grid or a wall. What magic and other lessons are lurking in the design, hidden until we could experience it?
