An international tech entrepreneur purchases an impossibly narrow piece of steep mountain slope in Austria, where he grew up. The building site will only allow for a 4-meter-wide house. This challenge sparks the interest of well-known architect Rem Koolhaas, but Rem has not built a private house since his acclaimed House in Bordeaux over 20 years ago. The process was captured by photographer and filmmaker Frans Parthesius, using primarily a simple static security camera. Slowly, the house reveals itself as the film reveals clues about Koolhaas's process.
