When livable space becomes scarce in densely populated cities, builders tend to move upward with high-rises and skyscrapers. But could the same concept be applied to outdoor recreational and green areas?

For the Shanghai-based firm 100architects, that’s precisely the plan. Vertical Times is a concept park that would rise six levels into the sky.

Welcoming locals and visitors, the proposed space would feature individual zones that include a carousel playground and ball pool for children, a hammock lounge and sky garden for adults seeking relaxation, and a restaurant and sky bar for those looking for a little more activity.

100architects’ proposal targets New York’s Times Square, which sees roughly 400,000 visitors every day.

Vertical Times would measure 40 feet in diameter and 180 feet tall, while each level would be 1,215 square feet. Built using a combination of concrete and steel, the structure would be reinforced with a central column, which would also hold an elevator
