Demens-Rumbough-Crawley House, Victorian residence on Park Avenue North in Asheville, United States.

The Demens-Rumbough-Crawley House, also known as Hanger Hall, is a two-story brick Victorian dwelling on a stone foundation at 31 Park Ave. N. in Asheville. Built about 1890, it has a low hipped roof, rigid and geometrical exterior ornamentation, and a projecting three-stage tower and bay. A small frame garage stands on the property.

The house was built around 1890 by Peter Demens, a Russian-born sawmill operator who later founded St. Petersburg, Florida. It remains one of the few surviving structures from the Prospect Park development of the 1890s, a period of rapid growth in Asheville.

Ida Jolly Crawley, owner from 1919, assembled art and geological collections in the house, making it a personal museum. The rooms displayed her own interests rather than those of earlier owners, and visitors can still see how one collector turned a residence into a showcase.

The property sits on elevated ground with good views of the surrounding area and is within walking distance of the French Broad River. The location makes it easy to reach other sites in Asheville's West End while offering visitors a quieter setting away from downtown.

The house is also known as Hanger Hall, a name it carries alongside the Demens-Rumbough-Crawley designation. Peter Demens, who built it around 1890, went on to found St. Petersburg, Florida, in 1888, so the Florida city predates this Asheville house rather than following it.
