The historic 1882 “Big Building” houses administration, weaving, clay, woodshop, art, music, Upper and Lower School music, and library. Studio spaces for math and science are located in other buildings on campus, and PE is based in our gym.

Individual classrooms surround the Big Building. The “East Side” of campus has our are Preschool through 6-7 year-old classrooms, and on the “West Side” are our 7-8 year old through 8th grade classrooms.
Younger students are free to play in their class yard, which are fenced in on the East Side, but on the West Side are defined by landmarks, providing practice in being held accountable to the agreed upon boundaries. Older students may roam and explore any part of the grounds including the popular rope swing, the tree house, playing fields, and Big Building.

The grounds are considered an essential part of the Peninsula experience. Our campus provides a sense of wonder, and students experience a strong feeling of ownership over them as they have the freedom to explore and play throughout the school property. One may witness children swinging on the rope swing, splashing through puddles, playing hide-and-seek in the thickets behind a classroom, or simply talking with friends in a tree.
