The energy of the Tate Modern sweeps over visitors the moment they walk down the ramp past the brightly-lit bookstore and ride the escalators past translucent green glass panels. Each half-floor contains up to 16 galleries with stark white walls and concrete or unfinished wood floors. The fifth floor rises two stories to a café, shop and auditorium. A lightweight luminous roof, fabricated from translucent panels, floods the galleries with light and offers breathtaking views of London.
