Hugging the Spuyten Duyvil Creek shoreline at the northern tip of Manhattan three small buildings serve Columbia’s rowing and tennis programs: Gould-Remmer Boathouse, Shell House, and the Dick Savitt Tennis Center, built from the 1920s through the 1990s. After many years of use, these buildings no longer met the needs of the Athletics Department. Urbahn analyzed current and future needs, documented physical and code deficiencies, and developed a range of conceptual design strategies with associated implementation costs. The minimal option included expanded lockers, accessibility improvements, and code compliance within the Tennis Center and Shell House. The moderate option provided greater programmatic expansion, along with an accessible connection between the Shell and Boat Houses. The maximum option involved a replacement tennis pavilion, a dramatic addition the Shell House, and significant retrofit of the historic Boathouse.
