Okay, I'll try to word the question better.

In the 1930s, Sigma Alpha Iota began securing "National Houses" in area hotels to serve as a space for all local chapters to hold business meetings, musicales, pledge services, initiations, parties, etc. The first one, called Chicago House, was at the Allerton Hotel on Michigan Ave. in Chicago. The second one, New York House, was established at the Tudor Tower on Prospect Place in New York. Where were two other SAI houses established?
