1. 2280 Andrews Avenue

Originally known as St. Andrews Court, this building in University Heights is a bit of an enigma. In sharp contrast to the Park Plaza Apartments, architecturally 2280 Andrews Avenue is for the most part a very ordinary building one wouldn’t give a second glance. All of its aesthetic flair is devoted to this extraordinary entryway, which is set back about 20 feet from the street in a light court. As a result, it seems like a hidden gem, particularly the first time one sees it, as it is not revealed until passing directly in front of it.
