St. Luke's Theatre served the English and Drama subject area as both a teaching space and a venue for student and professional productions. It was centrally located on the School of Education campus of the University of Exeter. The space is currently used as a seminar room, and for rehearsal by the School of Drama and Music.

The theatre seated 100 people on tiered bleacher seating, or up to 150 in a thrust stage arrangement. The space was much like a studio, but with very high ceiling and a modest proscenium. It was fully equipped for lighting and sound, had a 10m fly tower and a mid-stage trap to the basement.

It seems likely that the theatre will be converted into office space in the near future.
