Campus Master Plan

Integrating and unifying the campus. Punahou School has developed a master plan that contemplates the 76-acre campus in its entirety and takes an integrated approach to the evolution of built and open spaces. The Campus Master Plan was endorsed by the Board of Trustees in 2013 and is guided by key principles such as the reaffirmation of Ka Punahou as the School’s geographical, historic and spiritual center; increasing open and green spaces; making a large school feel intimate and nurturing; and reinforcing the arts as a core element in the learning journey of each child.

Sidney and Minnie Kosasa Community for Grades 2 – 5

The most recent phase of the master plan encompassed the redevelopment of the grades 2 – 5 community and creation of a Junior School Learning Commons, following the successful experience of Case Middle School and Omidyar K – 1 Neighborhood, where programs have inspired facility design that is flexible and student-centered.

The architectural firm Design Partners Incorporated was selected to work with the School on this project. Phase 1a of Kosasa Community welcomed students in fall 2016, and phase 1b welcomed students in fall 2019.


Education by Design

In 2018, Punahou School published "Education by Design," an 88-page publication showcasing the transformation of Punahou School's campus during the tenure of its president Jim Scott, who arrived in 1994 and will be retiring in June 2019. During this 25-year period, the school shifted from having mostly functional facilities to creating inspiring, student-centered learning environments. View the publication online below, and get a glimpse into the vision, planning details, fundraising efforts and careful execution of various capital projects Punahou School took on in the last quarter century.
