Since 2002, the campus has undergone a $20 million project involving both new construction and remodeling, funded by a county-wide sales tax.

A new 27,000-square-foot (2,500 m2) auditorium with modern band, chorus, dance and drama facilities opened in July 2003, along with a 6,000 sq ft (560 m2) multipurpose fieldhouse.

The main building remodeling includes a new media center (14,500 sq ft), CCTV studios, additional classrooms, relocation of the administration, and expanded applied technology labs.

The final phase, completed in 2006, provided practice fields and courts, parking and drainage improvements, and concession space.

Instead of having to pay for the removal, Lake Mary High School will be a “Chrysler Business Partner” and will promote the relationship.
