The Concourse Level sits directly below the Grand Mezzanine Banking Hall and gives 48 Wall Street a versatility that most single-floor venues cannot match. At 3,000 square feet with 14-foot ceilings, it accommodates up to 200 guests for a seated event or reception and divides into six separate breakout rooms for concurrent sessions and workshops. For full-day conferences, the Concourse handles parallel programming while the Grand Mezzanine serves the main stage. For weddings and galas, it works as a pre-function cocktail space or a private dining room. The two levels connect via the grand marble staircase, creating a natural and elegant flow for guests moving between them.
