A recently completed expansion and renovation of Wellesley College’s science complex yielded a modernized structure for 21st century STEM education while preserving important historical features. The project represents “one of the largest and most ambitious building
projects in the college’s modern history,” according to Wellesley College and Skidmore, Owings & Merrill (SOM), the project’s architects.
The building’s signature space, the Focus, a multi-story atrium, was created by enclosing the space between an L-shaped wing and the neighboring Sage Hall. The neo-Gothic brick facade of Sage Hall forms one wall within the modernist atrium, creating an interplay between old and new. Renovation of the L-wing preserved the architectural integrity of the space, including the original brick wall, while demolishing the rest of Sage Hall to make way for the addition. With expansive laboratory spaces and exposed concrete and mechanical systems, the L-wing boldly contrasts with the more traditional architectural styles of the Wellesley campus.
The project encompasses Science Hill—the setting for multiple science facilities. It linked the existing Whitin Observatory, the Global Flora Conservatory, the arboretum, and the botanic gardens. The new complex is immersed in a reimagined landscape, which introduces new gardens that will be used for scientific and ecological pedagogy. As part of the curriculum, the landscape will be installed by students and faculty next spring.
The new structure, distinguished by a ship-lapped, zinc-paneled facade, was conceived as a series of pavilions with strong connections to the outdoors. The interior layout organizes similar fields of study together, situating classrooms, faculty offices, and laboratories according to discipline.
A central spine, the Chao Foundation Innovation Hub, connects the mix of old and new buildings and makes them intuitive to navigate. Built with mass timber, this multistory cascade of spaces offers double- and triple-height interiors with views of the landscape. Breakout areas fill the space, with windows that reveal the laboratory spaces in the surrounding buildings, putting science on display and enhancing the sense of a village atop Science Hill.
The project significantly improved the Science Complex’s sustainability performance and plays a key role in the college’s goal of carbon neutrality by 2040. Before this project, the science buildings consumed more energy than any other areas on campus. Now, the complex is among the most environmentally efficient. Design measures such as stormwater capture, new piping and mechanical systems, more natural lighting, the use of mass timber and recycled zinc, and the preservation of as much of the original structures as possible, helped the project achieve LEED Platinum certification.
