Harriton High School is one of two new LEED Gold certified high schools designed by KCBA for the Lower Merion School District. Located on a tight 50-acre site that contained the existing high school (a collection of nine free-standing buildings) and associated parking and athletic facilities, a six-phase, four-year construction process was planned and implemented in order to maintain safe and seamless operation of the academic program through the construction and site restoration. The new 328,000 sq. ft. school features a diverse array of learning, activity, and support spaces to accommodate an enrollment of 1,250 students. In addition to a full complement of classrooms, science labs, and arts spaces, Harriton houses a lecture hall with tiered seating to help prepare students for the college environment, a black box theater utilized by several departments as well as the drama program, and a lofty, glass-encased library that serves as the building’s exterior focal point and interior anchor. Reflecting the school district’s commitment to sustainability, the building possesses a number of state-of-the-art features such as an underground storage tank which collects water from the roof and recycles it in the building as gray water to flush toilets.
