Harvard’s American Repertory Theater has about two years left in Cambridge before productions moves to a campus recently cleared for construction in Allston. Work will begin next year for an opening in 2026, according to the A.R.T. The scheduling was announced after unanimous approval of the plans Nov. 16 by the Boston Planning and Development Agency.

The A.R.T. – gearing up for “Real Women Have Curves: The Musical,” opening Dec. 6 – has been at the Loeb Drama Center on Brattle Street in Harvard Square since its opening in 1960. The last improvements it saw was in 2014 – but that was focused on restrooms.

“For the last four decades, A.R.T. has had a beautiful home at the Loeb Drama Center, but over time our vision has expanded and so has our work,” A.R.T. artistic director Diane Paulus said in a theater press release. “The intentional architecture of A.R.T.’s new home will galvanize creativity and collaboration and fuel our mission to expand the boundaries of theater for decades to come.”

The 70,000 square-foot center David E. and Stacey L. Goel Center for Creativity and Performance will include two flexible performance venues, rehearsal studios, teaching spaces, a spacious lobby and an outdoor performance yard designed to host ticketed and free programming at 175 N. Harvard St., Allston, the school said.

It will include 276 apartments for around 500 Harvard affiliates. “The creation of significant new university housing might reduce pressure on a stressed local housing market and create further opportunities for the Harvard community to more deeply engage in Allston’s creative and distinct neighborhood culture,” Harvard executive vice president Meredith Weenick said.

The school has not said what will replace the A.R.T. or Loeb Drama Center on Brattle Street.
