New York-based DFA Studio has unveiled plans for a soaring wooden tower in Central Park that could actually purify the heavily contaminated Jacqueline Kennedy Onassis Reservoir. The proposed tower measures 712 feet tall with a 112-foot-tall spire – and if it comes to fruition, it will be the world’s tallest timber tower.

The tower’s helix structure is wrapped with a lattice of curved timber beams. The building would be anchored securely to a pre-cast concrete base with tensile steel cables. A transparent material covers the tower’s exterior, providing 360-degree views as visitors climb up to the top.

The Jacqueline Kennedy Onassis Reservoir currently contains an estimated one billion gallons of stagnant, contaminated water. The tower’s filtration system could potentially convert the body of water into a clean pond.
“Aside from supplying water to the pool and Harlem Meer, the Reservoir sits stagnant and fenced off due to its current state as a health threat to millions of New Yorkers, tourists and animals,” said DFA studio founder Laith Sayigh. “DFA envisions a temporary landmark that is remarkably of its time to creatively transform the reservoir into one of New York’s boldest urban amenities.”
The tower’s integrated filtration system (as well as the elevators) would be powered by a wind turbine installed at the top of the tower. Sayigh believes that the NYC project would serve as an example for urban design around the world, “The Central Park Tower has the potential to be a model project for other cities aiming to fix existing infrastructure, build tall to capture views and elevate the urban public realm.”
