Chelsea High School, originally designed by Kingscott, has experienced significant growth in extracurricular participation, particularly in athletics and the arts. As these programs expanded, so did their space and resource requirements. To support this growth, the school underwent a thoughtfully planned addition and renovation, including updates to energy-efficient mechanical systems, ensuring a modern and sustainable environment for students and staff.
