The Honolulu House Museum was built as a private residence for Judge Abner Pratt in 1860 when he returned from serving as US Consul in the Sandwich Islands. The house, resembling the Executive Mansion in Honolulu he lived in, boasts of a wonderful blend of Italianate, Gothic Revival and Polynesian influence, the Honolulu House is built of Marshall sandstone and faced with vertical board and battens.

After a series of owners, the property was acquired by Mr. Harold C. Brooks, who wanted to protect it. After being protected by Mr. Brooks for 11 years, the Marshall Historical Society was able to purchase it in 1962.

Today, the Honolulu House is now occupied by the Marshall Historical Society while undergoing restoration. To recreate its 1880's magnificent state, its wall and ceiling paintings, carpets and furniture were thoroughly researched. While the society maintains it as a historical museum open to the public from May to October, building repair and replacement of moldings, railings, spindles and stairs is still being done to achieve its restoration and preservation.

The building is listed on the Historical American Buildings Survey and the National Register of Historic Places.
