The Theta Xi Fraternity Chapter House, an excellent local example of the Tudor Revival architectural style in the City of Troy, is located at 1490 Sage Avenue at the northern edge of Rensselaer Polytechnic Institute. Built in 1931, the fraternity house has undergone few changes, none of which detract from its original design or its original building fabric. The Theta Xi chapter house meets the requirements of Criterion C: Architecture for listing in the National Register of Historic Places.
Characteristics of this style as expressed in the Theta Xi house include its steeply pitched slate gable roof with intersecting gables, Tudor-arched limestone entryway, grouped casement windows, and tall chimneys. The building embodies characteristic features of the fraternity house type, as expressed in its various social spaces, its industrial kitchen, and its large number of small bedrooms. The Theta Xi house's historic integrity has been maintained over the years and the building continues to look and function much the way it did when completed
