Following the success of HMFH's Elementary and Middle Schools in Chelsea, the city called on HMFH to improve its relatively new high school.

When it was originally completed in 1996, the building was designed for 1000 students in grades 9-12 and was organized around a house system. With a surge in the 9-12 population and abandonment of the house system in favor of a departmental organization of the school, the client needed a larger, more flexible facility.

HMFH's design includes a four-story addition, as well as renovation and repartitioning in the existing building to make the former house layout more responsive to the high school's program needs. The 85,000 sf addition, which increases the school to 240,000 sf and will accommodate a total population of 1,500 students, includes general classrooms, four new science laboratories, a multi-purpose room, and a relocated Main Office.
