Over a decade ago Burling Slip Park in New York City inspired award-winning architect David Rockwell to conceive design and patent a large scale loose parts block system that revolutionized the way Parks engaged with their surrounding Communities. Imagination Playground was born. Imagination Playground is a breakthrough playspace designed to encourage child-directed unstructured free play. Unlike traditional hardscape playgrounds Imagination Playground is low cost requires no installation and can be used indoors or outside on a variety of surfaces. With a focus on loose parts Imagination Playground allows children to reconfigure their environment and design their own course of play building skills in creativity communication collaboration and critical thinking. The Blue Blocks come in three different sizes - Big Medium and tabletop Smalls. Made in the USA from closed cell waterproof foam the Blocks are resistant to mold mildew and microorganisms. They can be used indoors or outdoors on a variety of surfaces and are suitable for ages 2 and up. The Blue Blocks have become a beloved central feature in museums schools parks libraries and communities around the world. Today over one million children play with Imagination Playground blocks daily.
