ILA Penthouse hosts company meetings, receptions, dinners and weddings for between 10 and 225 guests across three connected spaces: the Bar Room, the Sanctuary and a 4,500 sq ft Rooftop Garden. The venue is at 253 West 28th Street in Chelsea, a block from New York City's Flower District, on the 7th floor with a penthouse level above.
Seminars and company events
The venue handles everything from cocktail hours and client receptions to full-day meetings and multi-day conferences. A meeting room seats up to 100, the Bar Room works for breakfasts, lunches and breaks, an additional green room sits in the office, and the rooftop is used for fresh-air pauses or an evening reception.
A sample conference day on the official site runs from a continental breakfast in the Bar Room, through a morning session in the Sanctuary and lunch in the Bar Room, to afternoon breakouts or panels and a rooftop cocktail reception. The Sanctuary offers multiple bars, lighting configurations, a sound system and A/V amenities, and AV packages can be added.
The venue also hosts brand activations, non-profit galas and private classes in floral design, mixology and wellness, since it is the home of FlowerSchool NY.
Weddings and receptions
Weddings and engagement parties use the combination of spaces, with in-house catering and floral design on site. The Sanctuary can take a seated dinner, a gala or a dance party, and the rooftop can be used for the ceremony or the cocktail hour. Planning support, menu creation, staffing and day-of coordination are handled by the venue team.
