An architectural landmark of downtown New Haven, the historic Ralph Ingersoll House (143 Elm Street) is currently the subject of a demolition delay, which will expire on June 10th.
The house was built in 1829 to designs by the celebrated architects Ithiel Town and Alexander Jackson Davis. A superb example of Greek Revival residential architecture, it is one of only a handful of surviving residential works by two of the most important American architects of the early nineteenth century. It stands just a stone’s throw from Town’s most iconic New Haven buildings, Centre Church and Trinity Church on the Green, which were constructed between 1812 and 1816.
In 1919, Harriet Williams donated the house to Yale as a memorial to her son, Earl Trumbull Williams, of the class of 1910, who died in 1918. The building was renovated by Delano & Aldrich (architects of several other Yale buildings, including the Divinity School, William Harkness Hall, and Sterling Chemistry Laboratory) and became the home of the Yale University Press.
Yale now seeks to demolish the 1-story rear porch of the building and construct a 3-story glass and timber structure with elevator to serve as an accessible entrance. While the New Haven Preservation Trust supports the goal of making buildings more accessible, we are concerned by the proposed project’s disregard for the architectural significance of the rear porch, which all evidence suggests is an original feature of the house.
Beyond the loss of the historic porch, we find the proposed 3-story glass addition to be visually incompatible with the historic building (and the streetscape as a whole), in its scale, materials, and detailing. The addition would be visible from the Lower Green, and its glass facade would be a source of light pollution at night.
The building’s inclusion in the Elm Street State Historic District and Historic Resources Inventory triggered the demolition delay, issued by the City, to allow time to discuss alternatives. The NHPT has has urged Yale to seek an architectural solution that would provide accessibility while respecting the historic structure, however to date the university has not expressed an interest in exploring alternatives to their original proposal.
