UChicago Child Development Center Stony Island
A Natural Place to Begin Life Long Learning When faced with the question “How do you design a day care for the children of future Nobel laureates?”, one approach held promise. Instead of creating another place dominated by primary colors and synthetic play equipment, children could be offered an opportunity to discover natural phenomena in the natural world. There, they would discover first principles first-hand, surrounded by minimally processed natural materials.

Consequently, the Child Development Center emphasizes the natural landscape over the built-one, centered around two playcourts with a footprint larger than the building itself. The playcourts conceptually graft onto the historic Frederick Law Olmsted landscape located across the street in Jackson Park. Natural materials, constructed from either the atmosphere (trees, plants, wood) or from the earth (boulders, rocks, sand), dominate. Boulders, some weighing as much as 90,000 pounds, were imported from the glacial till of central Wisconsin to create boundaries, pathways, and age-appropriate climbing opportunities. Waving layers of three different Midwestern stones fill gabion fences that encircle the east playcourt, ensuring visual privacy without creating a fortress. Natural bark siding, harvested from Yellow Poplar trees in North Carolina, clad the east wing. The Z-shaped building’s east wing provides spaces for infants and toddlers, while the west wing is dedicated to older children. Each age group has tandem classrooms with doors that open directly onto adjacent age-appropriate outdoor play areas. Low fences subdivide the playcourts, allowing younger children to readily observe older children while ensuring the exclusivity of their own environment. The playcourts offer shapes, textures, and experiences to engage. Rainwater cascades from the folded plate roof into splash tanks. A squash house, a live willow tunnel, a trike path, and sand and water zones encourage exploration. Different surfaces invite children to crawl, roll, ride, climb and walk-to experience their bodies moving in nature. Each playcourt includes a working garden where children learn about growing and harvesting food, nutrition, and sustainability. Chimes, fashioned from bamboo and copper, await a curious thump. The playcourts are used during all four seasons.
STRATEGIC INFILL The siting of the eastern wing, situated within the shadow of the adjacent 19-story residential tower, preserves as much sun for its playcourt as possible. Conversely, west of the tower, the wing is located to the north so that its playcourt can enjoy a generous exposure to the southern sun. The 13,300 square foot facility is more “lookwithin-me” than “look-at-me.” Rather than competing with the size or glamour of the adjacent University buildings, the focus of the center remains on the child’s perspective and outdoor play. Consequently, the richness of experience hugs the ground.
COMMUNITY The purpose of the building is to build human capital and community. First, it provides the University an exceptional child care option for competitively recruited faculty, staff, and the surrounding community. Secondly, it promotes social connections among new University parents who often work in different academic disciplines. While a generous lobby overlooking the east playcourt serves as the building’s emotional center and main social hub, other spaces such as a semiprivate room for nursing mothers and wide corridors lined with benches support impromptu interactions. The site borders a major commuter rail line to the west. With multiple major bus lines stopping along Stony Island Avenue, the site is well served by public transportation. Ample bicycle parking is provided for parents able to commute from the Hyde Park neighborhood.
INTEGRATING NATURE At the facility’s emotional center, formed by the overlap of the two classroom wings, families check-in by using a touch-screen monitor and connect with care providers. From this central location, children get a preview of their day: Full-height windows reveal the east play court as the natural bark siding extends inside. The adjacent gross motor room, ďŹ lled with an array of activities, has a wall of glass revealing the west play court. The folding roof ripples over both wings, allowing natural light into the classrooms below. Unlike most green roofs, the one covering the east wing is readily visible from the ground. If children learn what they live, they will not only learn from nature here, but they will learn to value it. The center is infused with this spirit. Additionally, the curriculum of the center is fully integrated with the mission.

Bioclimatic Design The exterior wall framing was insulated behind the gypsum sheathing with spray foam to provide an air tight barrier. Furring strips for the exterior cladding, which were fabricated to minimize thermal shorts, were installed over insulating sheathing. A green roof covers the east wing, and a reflective membrane roof covers the west wing.
Water Cycle Impact of rain water falling on the site of the UChicago Child Development Center before and after the construction for both 2-year and 100-year storm events. By reducing both rain water runoff and allowing on-site ground water recharging, a site that formerly discharged 100% of its runoff to the City’s sewers will now only discharge storm water for 11% of the storms occurring during an average two-year period.
Exterior Playspace The amount of secure exterior playspace provided at the UChicago Stony Island Child Development Center exceeds code minimums and NAEYC standards for both staggered and concurrent use of the play courts.
