What fits in this room

Smaller spaces are where most events actually happen, and The 4th Wall is one of them. A single-track day works; a programme with a trade floor attached does not.

  • networking mixers

    An independent space with its own character, which a mixer benefits from more than a conference does.

  • fundraisers and galas

    A room with a personality is worth more at a gala than square footage is.
