Gowanus Event Venue With Covered Atrium and Skylit Main Hall

501 Union is a restored 1916 building in Gowanus with three connected environments that guide guests naturally through an event. The covered atrium creates an inviting arrival and ceremony setting with the feel of an outdoor courtyard protected from the weather. A cocktail lounge with a marble bar, vintage details, and comfortable seating gives guests a separate place to gather before entering the skylit main hall. Exposed brick, signature chandeliers, high ceilings, and flexible floor plans allow the main room to support weddings, dinners, dancing, corporate events, holiday parties, launches, and creative productions without losing the building's industrial Brooklyn character.

A private getting-ready suite, catering support, eight accessible restrooms, climate control, tables, chairs, lounge furniture, sound and projection options, Wi-Fi, and wheelchair access help events operate smoothly. Outside caterers are welcome, while alcoholic beverages and bar service are handled exclusively through the venue. DJs and enclosed candles are permitted, and approved pets may participate in ceremonies. The property does not allow indoor smoking or independently supplied alcohol. With a legal capacity just under 300, 501 Union offers enough scale for a substantial guest list while keeping ceremonies, cocktails, dining, and dancing connected inside one thoughtfully organized venue. The sequence of atrium, lounge, and hall gives the venue a strong natural timeline, allowing each portion of the event to feel intentional while keeping all guests within the same accessible property.
