When the historic 19th century First Baptist Church of Dallas building burned down after Christmas 2002, the church decided to rebuild a much larger sanctuary building, with balcony seating, an administrative level, a two-story-high welcome center, and connector between the church and the existing fellowship hall next door.

The new, 600-seat sanctuary includes many of the historic details derived from photographs of the original building. The expanded sanctuary space features exterior and interior backlit stained glass windows, a raised stage platform with sprung hardwood floor, theatrical sound and lighting systems, and a retractable projection screen concealed over the Baptistery.  The baptistery is raised above the stage, with adjoining dressing rooms.

The bell tower houses a computerized carillon system.  Church administrative offices are on the lower level, together with choir practice rooms and several classrooms.

The Sanctuary Building is part of a master plan for the Church which includes Life Center, Fellowship Hall, and Education expansion.
