  1. ArchUp: Material & Programmatic Analysis of the Tang Wing at the American Historical Association

    This article examines the new Tang Wing (71,000 square feet) in New York as a case study in expanding conservative cultural institutions. To enhance its archival value, we present the following key technical and material data:

    The design features a granite facade sourced from the same Deer Isle quarry used in the original building (1908), achieving a 95% textural match to preserve visual continuity. The wing rises 8 stories, adding 6,600 m² of new space including flexible galleries (2,500 m²), a conservation laboratory (800 m²), and 10 classrooms with a capacity of 30 students each.

    Functional performance is distinguished by allocating 40% of the space to educational programs, including the American Academy of Democracy, which will host 30,000 students annually. The design achieves full spatial integration with the historic building through 3 transverse connecting corridors, a 1,200 m² green courtyard, and a rooftop terrace overlooking Central Park.

    In terms of museum integration, the wing will host the American LGBTQ+ Museum starting in late 2027, with climate-controlled archival spaces maintaining a temperature of 18°C and 50% humidity. The total investment amounts to $150 million, with an expected opening in June 2026, representing the largest expansion of the institution since its founding.
