The spacious, bungalow-style house is an excellent example of the Craftsman Movement in the design of its interior decorations. The Craftsman Movement, which became popular in the 20th century, was inspired by the English Arts and Crafts Movement of the late 19th century.
The house exists today unaltered and in exceptionally good condition, due to the excellent care taken by the previous owners and to the ongoing maintenance and restoration being done by the Stevens County Historical Society. Visitors to the Keller Estate will enjoy the interior of the house, which contains many distinctive and noteworthy features. Some of the original furniture is displayed in the dining room and the guest bedroom upstairs as well as some original wallpaper. The Society replaced some wallpaper in keeping with the style of the home. For the most part, the interior decoration is original and unaltered.
The City of Colville owns the Keller House, and the property site of the Stevens County Museum, which has a 99 yr. lease on the property commencing on July 1, 1975. By agreement, the complete facility is operated and managed by the Stevens County Historical Society. The facility is funded by donations, grants and the City of Colville.
