The Henry Weis House is a historic building located in Waterloo, Iowa, United States.
 Weis was a factory owner that produced egg case fillers, which were used to protect eggs during shipping.
 He engaged the local architectural firm of Murphy & Ralston to design this house, which was completed in 1902.
 Architecturally, the two-story frame structure is "transitional" in its design, featuring elements of the Queen Anne and the Colonial Revival styles.
 The Queen Anne is found in its irregular plan, wraparound porch, full-height bays, small second floor porch, and the small screened porch.
 The Colonial Revival is found in the Ionic fluted porch columns, and the consoles with a row of dentils located along the cornice.
 The house also features foliated designs on the gable ends.
 It remained in the Weis family into the 1930s when it was converted into apartments.
 It has subsequently been converted into a bed and breakfast.
 The house was listed on the National Register of Historic Places in 1989.
The Benjamin Franklin Coppess House, built in 1882, is a historic Queen Anne and Stick-Eastlake style house located at 209 Washington Street in Greenville, Ohio, United States.
 Featuring an unusually detailed Stick-Eastlake brick facade, the Coppess House is a T-shaped building that is supported by a stone foundation; the roof is asphalt, and minor elements of stone are also visible.
 A large enclosed porch and a veranda wrap around the "lower" portion of the "T", which faces the street, while above and behind the porch, placed at the base of the "T", sits a large bay window.
 The porch is among the most significant components of the building, due to elements such as exquisitely detailed arches formed of tiny spindles, which sprout from columns meant to resemble massive table legs; one must walk under one such arch to use the porch's main entrance, located on one of its corners, and three more such arches are placed on the front and on the side to either side of the entrance.
 Small gables are placed over the porch's main entrance and a subsidiary one, decorated with small sculptures, both carven and molded.

 The structure was built by local masons George Brooks and Ira McMullin of local red sandstone, with finished ashlar masonry by Brooks in the front and coursed rubble stone by McMullin on the other three sides.
 A parapet surrounds the single-slope roof on the front and sides.
 The main level is divided into two equal-sized rooms, each with two front entrances and a rear entrance, with a vault on one side.

 The Wells Fargo building was used as a mine supply store in the late 19th century, then for a time as the residence of the Colbath family.
