Built for Aaron H. Maegly (born 1854), a wealthy Portland broker, the distinctive house was completed in 1915.

[4] The house is constructed of reinforced concrete, covered by stucco, and has a red tile roof.

Among the features of the Maegly House that are often included in Prairie School-style dwellings are decorative corner brackets and ornamental friezes, above and below the second-floor windows.

One narrow frieze positioned just below the eaves encircles the entire house except where interrupted at the corners by the decorative brackets.

The home is surrounded by a garden notable for its collection of Japanese maples, planted by Aaron Maegly's wife.
