The interior, however, is something special. An intricately composed Rubik's Cube of glass and concrete, it creates dozens of spaces for different kinds of activities, separated from each other with varying degrees of opacity and yet still loosely bound together with a central light well. Clear exterior walls on the main floors bring the surrounding neighborhood in, making inhabitants feel as if they're suspended in the air, while the bulbous breakout rooms provide a greater sense of enclosure. The three levels also allow more raucous activity to settle to the more community-centered ground floor—Saturday was open house day, with kids racing around yelling—while adult activities can take place in relatively tranquil top-floor study areas.
