Three Dumbo office buildings have been updated with new rooftop amenity spaces designed by James Corner Field Operations. 45 Main Street, 55 Washington Street, and 20 Jay Street represent three anchor office buildings in Dumbo for real estate development firm Two Trees Management.

The new rooftop spaces range from 8,500 to 11,000 sf and include outdoor conference rooms, picnic and dining areas, spaces for screenings and outdoor yoga, and plenty of space for plants. Flexible seating can accommodate those looking to work, collaborate, or relax.

45 Main Street’s new 9,520-sf rooftop comprises a series of seven alcoves that line the edge of the roof, two herringbone-paved carpets with moveable furniture, a raised wooden deck that acts as a multi-purpose room, and views of the Manhattan Bridge. An abundance of planters, containing serviceberry, grey birch, flowering dogwoods, hydrangea, and witch hazel, separate the different spaces.

The rooftop at 20 Jay Street is the smallest of the three at 8,175 sf. A V-shaped raised wooden deck functions as a multi-purpose room with the Manhattan skyline as the backdrop. A custom-designed screen provides a surface for watching movies and also frames the deck. Large outdoor conference and dining tables, flexible seating with moveable tables, and chairs and chaise lounges are also included.

The 55 Washington rooftop provides 11,135 sf of space and is organized by a raised wooden promenade lined with shade trees and furnished with custom benches. The Manhattan Bridge can be viewed from one side while the Brooklyn Bridge can be viewed from the other end. A wooden ramp surrounded by plants leads to the social promenade. An additional three ‘rooms’ step off the promenade: a lounge, an outdoor conference room, and a picnic and dining area.

“Our design goal was to provide unique, lively gathering areas within lush settings in the center of a thriving urban environment while optimizing expansive views of the Brooklyn and Manhattan Bridges and the Manhattan skyline,” says Lisa Switkin, Senior Principal, James Corner Field Operations.

Each rooftop is finished and open for use.
