The Paulsen Building is a historic seventeen story building on Riverside. It has a beautifully decorated exterior and the lobby (which is accessible to the public!) has a painted ceiling, ornamentation above every door, and a display of old elevator mechanics. The Paulsen Penthouse used to be owned by Helen Paulsen and her husband started living there in 1957, according to a Spokesman Review article. Helen lived there in the '80's, even after her husband died, but currently the space is used by Bozzi Media as an event space.
The lobby with it's painted ceiling and multiple friezes and carved ornaments are open to the public. If you're ever walking by on Riverside, you should definitely stop in!
