A modular wall system with an integrated pocket door includes a frame defining a wall plane and a doorway. The system also includes one or more aesthetic panels connected to at least a portion of the frame so as to cover at least a portion of the wall frame. Additionally, the system includes a support member extending above the doorway and across at least a portion of the wall plane. The support member includes an integrated track that is accessible through one or more access windows integrated into the support member. The system includes a slideable pocket door integrated into the track such that when closed, the pocket door blocks the doorway, and when open, the pocket door is at least partially enclosed behind the one or more aesthetic panels.
