US-based designers Yitan Sun and Jianshi Wu have proposed converting Central Park in Manhattan into a sunken area encircled by houses, offices, cultural and retail space.
Named New York Horizon, the proposal won eVolo’s annual skyscraper competition, in which architects and designers had to provide their ideas for futuristic towers.
In their design, Sun and Wu suggested building 1,000ft-high glass walls around the excavated Central Park, reported Designboom.
The re-imagined park would feature hills, meadows and lakes, while excavated soil would be moved to various nearby localities.
Sun and Wu were quoted by Dezeen as saying: "The ambition is to reverse the traditional relationship between landscape and architecture, in a way that every occupiable space has direct connection to the nature."
They also added: "This creates a new urban condition, where landscape can serve as an inherent part of the city.
"With its highly reflective glass cover on all sides, the landscape inside the new park can reach beyond physical boundaries, creating an illusion of infinity.
Once excavated, the 100ft deep structure will have a floor area that is 80 times bigger than the Empire State Building, reported Lost At E Minor.
