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 current phase of the master plan encompasses 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 will welcome students in fall 2019.


Realignment of Piper’s Pali - COMPLETE

The realignment of Piper’s Pali toward the Diamond Head edge of campus created additional space for the future grades 2 – 5 facilities. Road construction work began in late July of 2014 and was completed in spring of 2015.

Construction of First Four Classroom Studios - COMPLETE

Construction of the first four of seven total two-story studios in the new grades 2 – 5 community began in March of 2015. These four studios were built to house 16 of 28 new classrooms, and opened for the 2016 – 2017 school year. In preparation for the construction, Winne Elementary Units C and D were removed during this phase.

Here’s the culmination of Phase 1A construction completed in August 2016...

Completion of Grades 2 – 5 Community - IN PROGRESS

Following completion of the first four studios, construction began on the remaining 3 studios (12 classrooms), the K – 8 Learning Commons and the visual and performing arts building. It is anticipated that construction will be completed and ready for use in the 2019 – 2020 school year.

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.
