The Site Development Plan advances Yerkes Observatory’s mission by uniting its rich legacy with a new era of connecting science, nature, history, and the arts. Home to the world’s largest refracting telescope, Yerkes has been a center of discovery for over 120 years. Rooted in the design legacy of the Olmsted Brothers who prepared the initial site plan in 1906, sweeping vistas and formal geometries define the site. The Site Development Plan preserves, enhances, and restores the historic site character while creating flexible spaces that support future programming, events, and experiences.
In collaboration with Yerkes Future Foundation, Saiki Design facilitated a planning workshop that informed the Observatory’s 2024–2034 Strategic Plan. This collaborative vision laid the groundwork for the Site Development Plan, which is centered around the addition of a Visitor Center, strategically placed adjacent to the historic Observatory. Reconfigured circulation improves arrival experiences while preserving the monumental Ellipse, a key part of the Olmsted Brothers plan. Clearly defined trailheads and a varied path network improve accessibility and orientation, accommodating a wide range of visitors and encouraging exploration.
As part of this transformation, Saiki Design is leading the implementation plan for Play/Space at Yerkes, a Monstrum-designed playground nestled in the former Director’s House site. Play/Space features fully accessible interconnected zones that support diverse sensory and social needs. Incorporating nature-based elements and supernova-themed play structures, Play/Space encourages imaginative exploration and inspires curiosity about astronomy in an inclusive, educational environment.
Additional flexible open spaces and gathering nodes are integrated throughout the site to support educational programs, seasonal events, and informal use. Ecological enhancements replace turf with resilient native plant communities, reducing maintenance, supporting biodiversity, and creating immersive, educational landscapes. Together, these improvements honor Yerkes’ past while shaping a sustainable and inspiring future.
