In 1981, a crowded hotel lobby in Kansas City became the site of a devastating structural collapse—one that killed 114 people and injured over 200. No earthquake or explosion triggered it. Instead, a single, seemingly minor design change slashed the skywalk’s capacity in half and sealed its fate. In this video, we break down the Hyatt Regency disaster from the frantic design-build process to the tragic aftermath, shedding light on the oversights, misunderstandings, and ethical lessons that reshaped engineering and architecture worldwide.

__Key Points__
1. The “J.C. Effect” Lobby – How Hyatt’s spectacular atrium design pushed the limits to impress guests.
2. Fast-Track Construction Risks – Overlapping design and building phases that left little room for error.
3. Critical Design Flaw – How splitting a steel rod into two segments transferred double the load onto a single beam.
4. Aftermath & Investigations – The massive National Bureau of Standards report, lawsuits, and changes to industry oversight.
5. Lasting Impact on Ethics & Practice – How the American Society of Civil Engineers strengthened accountability and reformed professional standards in the wake of the tragedy.

The Nakagin Capsule Tower was one of the most prominent constructions from the Metabolist movement. It was designed in 1972 by Kisho Kurokawa to serve a growing population of mobile business person in Tokyo, Japan. It was composed of 140 capsules attached to concrete towers. These 100 sf units were designed to be removable and replaceable over time. However, the building stood for 50 years without a single unit being replaced. Finally, it fell into such disrepair that it needed to be demolished. This video tells the story of the Nakagin Capsule Tower, its design, construction, life, and ultimate demise.

![Exploring a LOST Geometric Wonder [One Half House by John Hejduk]
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 focuses on a single house — the One Half House — designed by architect 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 the architect 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?
