What fits in this room

The seats do not move, which is the whole trade. You get sightlines, acoustics and a lighting rig you would otherwise have to rent, and you give up the ability to put tables in the room. August Hall is 9th of 45 such houses mapped in San Francisco.

  • award ceremonies

    Fixed seating, sightlines and a lighting rig are the hard parts, and they are already here.

  • product launches

    A single-track room with a real stage is the right shape for a launch.

  • multi-track conferences

    Works as a plenary house with breakouts booked elsewhere in the city.
