Big U by Bjarke Ingels Group

The Big U is a protective system around Manhattan in New York City, designed by Bjarke Ingels Group, driven by the needs and concerns of its communities. Stretching from West 57th street south to The Battery and up to East 42th street, the Big U protects 10 continuous miles of low-lying geography that comprise an incredibly dense, vibrant, and vulnerable urban area.

The proposal consists of separate but coordinated plans for three contiguous regions of the waterfront and associated communities, regions dubbed compartments.

The compartments work in concert to protect and enhance the city, but each compartment’s proposal is designed to stand on its own.

The Berm also offers pleasant, accessible routes into the park, with many  unprogrammed spots for resting, socializing, and enjoying views of the park and river.

Between the Manhattan Bridge and Montgomery Street, deployable walls are attached to the underside of the FDR Drive, ready to flip down to prepare for flood events.

At night, lighting integrated into the panels transforms a currently menacing area into a safe destination. Panels can also be flipped down to protect from the elements, creating a seasonal market during the winter.

Enhancing the public realm while protecting the Financial District and critical transportation infrastructure beyond, the Battery Berm weaves an elevated path through the park. Along this berm, a series of upland knolls form unique landscapes where people farm, sunbathe, eat and engage with world class gardens.

This signature building features a “Reverse Aquarium” which enables visitors to observe tidal variations and sea level rise while providing a flood barrier. Text by Rebuild by Design.
