Thus, Centerbrook’s proposed building is a symmetrical but idiosyncratic complex of pavilions on two levels. These break down the scale of the large institution into residential size elements that create courtyards front and back. These buildings are all covered in white clapboard with red roofs, and are fenestrated with traditional shape windows with louvers (looking like shutters) for modern day energy savings. Several are large at appropriate locations.

The entry drive, snakes through the woods to a formal entry court facing an outer pavilion on axis. The drive court is surrounded by an arcade of arches, another bow to the original estate. Hidden above the arches is a second-floor passage between pavilions that is all glass on its far side. The arches themselves form a welcoming porch that leads into the lobby and to the large underground library vault set into the hill behind. Work and meeting spaces, on the other hand, are filled with (louver controlled) daylight on both levels.

The rear, upper court above the vault is a park, a place for outdoor meetings, reading, and celebration. In the center of that court is a skylight for the lobby disguised as an old covered estate well. Behind it is a presentation amphitheater set into the continuing hill and leading to estate walking paths.
