Princeton University has completed a transformative renovation of Prospect House, its 1852 Italianate mansion, blending historic preservation with inclusive, contemporary design. Long serving as a meeting and event space, the building’s interiors were outdated and inaccessible, prompting the university to “press the restart button,” according to architect Ron McCoy. The project focused on accessibility, modern amenities, and celebrating diverse artistic voices while honoring the building’s layered heritage.
Designed by Philadelphia architect John Notman as a private home, Prospect House was donated to Princeton in 1878 and later became the residence of university presidents, including Woodrow Wilson. Over the decades, architects including Pietro Belluschi, Warren Platner, and Robert Venturi contributed to its evolution. Verona Carpenter Architects embraced this “layered” history in a 28,270-square-foot, three-story overhaul that retained key architectural features while modernizing interiors, systems, and accessibility.
Inclusive and Accessible Design
The renovation prioritized accessibility and sensory inclusivity. The front steps were expanded to include gently sloping ramps, and a glass-paneled door replaced the original solid wood, offering transparency and views through the building. Interior spaces feature a wide palette of wall colors inspired by the building’s stained-glass dome, ranging from robin’s-egg blue to aubergine, accommodating a variety of sensory preferences. Furnishings provide options for different postures and activity levels, with rockers, low- and high-backed chairs, and backless options, reflecting the firm’s commitment to inclusivity.
Modern Technology and Facilities
State-of-the-art MEP, audiovisual, and kitchen systems were installed to support contemporary events. The Garden Room, a glass-wrapped restaurant, received acoustic insulation and custom carpet tile, merging indoor and outdoor spaces while improving the dining experience for the hard of hearing. Furniture and finishes throughout were sourced from diverse designers, including women and people of color, reflecting Princeton’s commitment to representation and equity.
Art and Cultural Integration
The renovation also emphasized contemporary art and inclusive representation. Original portraits of former presidents were replaced with artworks from students, staff, faculty, and alumni, curated by the Princeton University Art Museum. Even room names were changed—for instance, the Presidential Dining Room is now the Rose Room—to eliminate exclusivity and foster a sense of belonging.
Preserving Legacy
Despite the modernization, Prospect House retains its historic character. The stained-glass dome, two-story chandelier, and black-and-white marble floors in the rotunda were meticulously restored. Other architectural details, such as the brownstone façade, window frames, and staircases, were refurbished to maintain the building’s original charm.
Strategic Impact
The renovation demonstrates how historic buildings can meet contemporary needs while honoring legacy. By integrating accessibility, modern systems, diverse art, and inclusive furniture, Princeton has created a space that welcomes a broader range of students, faculty, and visitors, ensuring Prospect House remains relevant for the 21st century.
