A 1930s art-deco building that originally was a dormitory for nurses will reopen in 2019 as affordable apartment housing for seniors priced out of their downtown Denver neighborhood. Tammen Hall, an eight-story, blond-brick beauty with gargoyles, terrazzo floors, a marble fireplace and vaulted ceilings in its grand entryway, will have 49 one- and two-bedroom apartments for people who are at least 62 and qualify based on income. The hall sits next to Saint Joseph Hospital, near 19th Avenue and Ogden Street in Denver, and is within walking distance to grocery shopping, public transportation and restaurants.
