Following the successful Broadway run, which nabbed two Tony Awards for Best Book and Best Featured Actor, BSC made the move to a more permanent home in Pittsfield, Massachusetts.

The company which was previously housed in the Consolati Performing Arts Center at Mount Everett High School in Sheffield, Massachusetts, purchased and renovated the Berkshire Music Hall in downtown in 2005.

When Barrington Stage Company purchased the building in 2005, the venue underwent a full renovation and became a 520-seat theater, opening its doors in the summer of 2006, under the name The Boyd-Quinson Mainstage.

[4][5] The play showcased the sex therapist's life from fleeing the Nazis in the Kindertransport and joining the Haganah in Jerusalem as a scout and sniper, to her struggles to succeed as a single mother coming to America.

[7] Mark St. Germain's Ears on a Beatle, The God Committee, and Freud's Last Session, are all plays that were initially produced at BSC, which transferred to New York for Off-Broadway runs.

Past Grand Prize winners include Stacey Rose’s America v. 2.1: The Sad Demise & Eventual Extinction of the American Negro, and Daniella De Jesus's Get Your Pink Hands off Me Sucka and Give Me Back.

The Burnt Part Boys ( Chris Miller and Nathan Tyson) was produced at Playwrights Horizons, and Funked Up Fairy Tales (Krisitn Childs) continued to be developed at the Sundance Institute.

Additionally, Robert Maddock and Joe Iconis's The Black Suits received a workshop production in 2012 before its world premiere at Center Theatre Group.
