The Rockwell Group and NYC Parks unveiled their plans last week to turn a 1.5-acre section of Betsy Head Park in Brownsville into a lush and active playground. When designing Imagination Playground, the firm looked to treehouses for inspiration. The site will feature a winding ramp that snakes around London Plane trees and connects to slides and a series of jungle gyms that spill out into an open area with sand, water, benches, and plantings. In collaboration with landscape architecture firm MKW + Associates, the Rockwell Group has taken on this project pro-bono and will donate a set of Playground Blocks to the Brownsville Recreation Center. The $3.92 million playground was funded with the help of government subsidies from Mayor Bloomberg, Borough President Markowitz, and Council Member Mealy. Partner David Rockwell founded Imagination Playground in partnership with NYC Parks and KaBOOM, a non-profit organization, to encourage activity and unstructured play for children at nominal cost by providing loose building blocks in outdoor recreational spaces. Right now the project is slated to break ground in spring of 2014 and open in 2015.
