Are they human-size nests? In 2009, New York artist and treehouse designer Roderick Romero built a two-story treehouse in a Southampton backyard that eerily emulates nature. With its interweaving recycled lumber, scavenged wood, vines and driftwood to line the open-air platforms, the result is a stunning visual feat that resembles bird nests.

Romero’s latest installation is at Brooklyn Botanic Garden. Using some of the wood from the gardens’ trees that fell during superstorm Sandy in October, he has created an open-air treehouse that is 200 square feet and 5 feet off the ground. It can hold up to 20 visitors at a time and opened to the public April 6. For more information, visit
