According to a city architectural inventory (PDF), Hampton Hall was built in 1928, and the architect was H. G. Hodgkins, who seems to have been based in Chicago, to judge by listings in Chicago trade magazines that show up in a Google Books search.

The interior includes quite a bit of Nemadji tile, and old Pa Pitt had never heard of Nemadji tile until he found this page on Hampton Hall from a site of Historic U. S. Tile Installations. The exterior is fairy-tale Tudor, designed to make apartment dwellers feel as though they were great lords of Queen Elizabeth’s time.

The entrance is flanked by bears holding shields, as bears are wont to do.
