Its walls are mud-mortared adobe brick, two courses thick, finished with cement and lime plasters over a fieldstone and concrete foundation. A wide wraparound porch covers the west and north sides. Over time the original open central courtyard was roofed over, and a board-and-batten addition was added at the rear around the 1950s. Original outbuildings survive nearby: a two-story barn, three sheds and a below-grade concrete cistern, all dating to about 1910. The property has served as a house and later as part of an equestrian center. It was listed for its architecture, as an example of Victorian Adobe and Adobe Revival building, and for its potential to yield historical information. The form reports high integrity, though the northeast wall shows moisture damage.","period_of_significance":"1910","architect_builder":"Mohnike, Charles Frederick","architectural_style":"Late 19th and Early 20th Century American Movements: Victorian Adobe/Adobe Revival","criteria":["C","D"],"status_note":"Historic and current function is single dwelling.
