PurposeAssessing performance art has shifted toward an audience-centric approach, with various factors impacting audiences’ holistic experiences in a theater. Existing theater marketing research has predominantly focused on servicescapes, leaving a research gap regarding audiences’ spatial experience within theater buildings.Design/methodology/approachTo address this gap, this case study collected crowdsourced data from mainstream social media platforms, including rating scores, textual reviews and reviewer-uploaded photos. The aim was to explore to what extent the theater architecture design impacted audiences’ theatrical experience. The old and new facilities of the case study theater were compared, and a series of quantitative and qualitative techniques were applied for data analysis, including statistics, content analysis, sentiment analysis and thematic analysis.FindingsThe study identified five major themes in social media review: the show, architectural design and attributes, staff and service, neighborhood and amenities, and financial consideration. Comments about theater architecture constituted a substantial portion of reviews, with seating comfort, intimacy and stage visibility being frequently discussed features. Seven subthemes related to architectural design emerged as key contributors to audiences’ spatial experiences, including aesthetics, design and spatial configuration; the bar and lobby; the new facility; seats; sets and stage; acoustics; and intimacy and atmosphere.Originality/valueThe study places the individual experiences of audience members as central and uses an inductive approach to analyze their self-generated data. The research results offer valuable insights into theater design and confirm the belief that architectural design has a significant impact on the overall theatrical experience of audiences.
