The Nakagin Capsule Hotel Tower in Shimbashi was the first of its kind in the world; a wholly modular building comprised of a concrete stack with latch-points for pre-fabricated one-piece rooms to bolt on to, with a built-in life cycle for obsolescence and upgrade. The work was the real-life embodiment of master architect Howard Roark's vision, a character from Ayn Rand's seminal Objectivist book The Fountainhead- a building so perfectly self-contained, ergonomic, and integrated that it would allow the whole of humanity to live in ultimate comfort with maximum efficiency- the true victory of function over form.
