The scheme divides the building into three parallel zones. The front zone contains all the active, information-gathering program components, including the stacks. The rear zone contains all of the meeting and program spaces, which have off-hours community use. The middle zone is very transparent, with alternating gardens and glass pavilion reading rooms. By creating several small garden spaces rather than a single large garden, each reading room is able to have a garden on both sides. This organization allows a beautiful specimen Beech tree to be preserved in one of the gardens.
