The part with the newer façade is actually two buildings that were remodeled/refaced into one façade somewhere around the 1930's. The corner building was originally called the Noyes Block and was built in 1866. The next building east was a grocery store owned by the Milnes family. The old hotel rooms on the upper floors formed the annex of the old Arlington Hotel, which stood on the north-west corner of North Hanchett Street and West Chicago Street and was demolished in the mid-1970's during Urban Renewal. There used to be an enclosed 2nd floor walkway linking that building to the Arlington Hotel. Some people colloquially refer to it as the Taylor's building, as Howard and Lola Taylor used to run a bookstore/stationery store in that building. Here's a picture c. 1890 of what the front façade used to look like prior to the remodel.
