It has two stages: the 824-seat Main Stage, which is similar to a Greek amphitheatre without aisles, balconies, pillars or boxes, and the Door: a flexible black box that can seat between 140 and 190.
 
The Main Stage tends to present a contemporary programme that focuses on new writing, cultural diversity and productions for families and young people; the Door specialises in new writing and experimental productions.

The Rep is subsidised by Birmingham City Council.

The Rep closed for building work in January 2011; it will be linked to the new City of Birmingham Library by a joint foyer; both buildings will share a bar, restaurant, studio theatre and external amphitheatre; completion is scheduled for 2013 (News Archive 10/01/11).

It has two stages: (1) the Main House which can be arranged traverse-style (capacity 360) or as a traditional proscenium arch (capacity 342) and which contains traps, an orchestra pit and full-height fly tower; and (2) the Ron Barber Studio (capacity 120) which is a flexible performance space without fixed seating.

The resident company, which employs a professional management team, has an unpaid membership of around 250 technicians, actors and set designers. It includes a youth section that has nurtured several stars.

The resident company hosts around 15 productions annually. The theatre also stages plays by visiting companies, both amateur and professional.

The facilities include a licensed bar and coffee lounge.
