The Johan Poulsen House is a three-story American Queen Anne Style mansion in Portland, Oregon's Brooklyn neighborhood.

[3] Poulsen sold the house immediately to S. B. Willey, probably either due to financial issues caused by the lead-up to the Panic of 1893 or because his wife, Dora, did not like it.

[5] It is considered a "Pacific Northwest interpretation of the Queen Anne Style", since it does not contain stone or brick.

[4] In 2017, the Poulsen House was purchased as a home for Prospect, a Portland communications, design, government relations, & digital media agency.

[3] Inman had an almost identical house at 6th and Woodward Street, which was demolished in 1958 to make room for a parking lot.

[3] The large lumber mill had a conveyor belt piling sawdust, which went to a Portland General Electric plant located next door.

[3] Poulsen built another large house on Hassalo Street in the Lloyd District, replaced by a Red Lion hotel later.
