GREENWICH - After years of planning, construction is now underway on a new auditorium and music space at Greenwich High School.

School officials say the new auditorium will have about 1,300 seats.

Once the auditorium is built, the plans call for knocking down the existing auditorium and building classrooms for music programs.

Officials say the entire project is expected to cost $44 million and take up to three years to complete.
