Located on the southwestern corner of 24th and R streets, Channel 24 is a new 42,800-SF, two-story live entertainment venue by Another Planet Entertainment, the only independent, locally owned and operated full-service concert production company in the San Francisco Bay Area and Northern California. The structure’s aesthetics call back to the site’s original industrial use, featuring large industrial sash windows facing 24th street—revealing the activity in the upper and lower lobbies— taut exterior metal cladding and a generous marquee awning over the corner entrance at R street.  The 2,150-occupancy venue features a near column-less house interior with 100-foot-long structural steel roof trusses that span across it. The tiered second-story balconies, cantilevered 35 feet into the house interior, are equipped with tuned-mass dampers (TMD) to mitigate undesirable harmonic vibrations induced by frenzied concertgoers. The design also includes 12-inch fully-grouted concrete masonry walls and nine inches of concrete fill over the roof deck to isolate concert music from the surrounding residential neighborhood. Miyamoto’s design incorporated construction phasing that was necessary to accommodate tight site constraints. We navigated these challenges, along with an aggressive schedule, with our design partners CAW Architects and Ellis Architects.
