Wondercabinet worked with staff from the Planting Fields Foundation, New York State Parks, and the project architect to convert the historic Hay Barn building into a new Visitor Center and to improve wayfinding and orientation throughout the estate.

The Visitor Center's exhibits interpret the arboretum's horticultural diversity, the estate's history, and its landscape and architectural design. A topographic map with orientation information helps visitors plan their visit, and includes peak blooming times for plantings across all seasons. Children can play with hands-on interactives while parents plan their visit. These interactives create context for a visit through the arboretum's buildings and grounds.
