Architecture Lecture Hall

A lecture hall where my design history class meets was designed in the 1970s as a fan-shaped auditorium with stepped seating that angles down toward a stage. Acoustics are good enough that the professor doesn't need a microphone even with 150 students in the room. Sight lines work from every seat because the fan shape means nobody is directly behind the person in front of them. Desk surfaces are wide enough for a laptop and a notebook side by side. Natural light comes from clerestory windows along the back wall, falling on the audience rather than on the projection screen — solving the common problem of having to darken a room completely to show slides. I've spent more hours in this room than any other space on campus, and I've started noticing details that I missed in my first year. The ceiling is angled to reflect sound from the stage upward and outward, the carpet in the aisles absorbs footstep noise from latecomers. Seats are spaced far enough apart that you can get to the middle of a row without making everyone stand up. These are solved problems in auditorium design, but experiencing a well-designed lecture hall makes you realize how many poorly designed ones you have sat in without thinking about why they felt wrong.
