An architect has revealed the design for the fourth and final tower at the World Trade Centre in New York City.
Danish architect Bjarke Ingels said 2 World Trade Centre will be 80 storeys high and appear as seven separate boxes stacked together.
At 1,330ft, it will be shorter than One World Trade Centre and will be New York City's third tallest building.
The tower is scheduled to open in 2020.
In a statement, Mr Ingels said the design will unite the streetscapes of Tribeca with the downtown towers.
From Tribeca, 2 World Trade Centre will appear as a vertical village of singular buildings on top of each other. From the trade centre, the stepped-back design will appear unified.
News Corp and 21st Century Fox have signed tentative leases for the building.
