Students at Sarasota School of Arts and Sciences are just about to move into new digs — and finally have enough room.

The school has 750 students and has been overcrowded for some time in the old warehouse it’s currently in. Next week, students will start attending classes in a brand-new, three-story building. Space is so tight in the old building the cafeteria doubles as three classrooms. So at lunchtime, some teachers haul their teaching materials in a cart to empty classrooms; after lunch, they move back. The new 40,000-square-foot building includes 31 classrooms and a music room big enough to accommodate the school’s 72-piece band. It also includes martial arts and dance studios and a performing arts room with a stage.
