On October 1, 2007, the Shakespeare Theatre Company opened the 774-seat Sidney Harman Hall in the heart of downtown Washington, D.C. Together with the existing Lansburgh Theatre, the two venues form the Harman Center for the Arts, a 21st-century performing arts center and expanded stage for the Shakespeare Theatre Company and Washington 's performing arts community.

Sidney Harman Hall occupies the first five and one-half floors of an 11-story office tower. A three-level glass façade curtain wall is distinguished by a projected bay window, connecting the activity within to the surrounding urban street life. The new facility allows for a wide variety of staging configurations—proscenium, thrust, semi-arena or bare—as well as for the presentation of dance and music events. Acoustically, the space has been rendered for the spoken word, and also can be easily adapted for chamber music as well as live, amplified or recorded music.

The Hall provides a variety of elementary stage configurations—proscenium, thrust or semi-arena—through the use of: a removable proscenium; a series of seating units on movable wagons for three-quarter or "in-the-round" viewing; a stage floor extension over a small lowered pit to create a thrust stage; and a series of movable acoustical wall panels, arranged in a semi-circle in front of the proscenium, which renders an environment for chamber music or solo recital concerts.
