There are four historic buildings plus one other historic structure located in the property. The historic buildings are located on a parcel within the larger ranch property. The historic ranch complex includes a house, barn, pump house,
privy, and
corrals. All of the structures on the ranch except the original barn were built by the Roba family using logs, lumber, hand-cut shingles, bricks, and locally quarried
tuff stone. • The
ranch house was built in 1910. It is a -story rustic
Victorian style building. The building's
foundation is tuff-stone. The same stone was used to construct the first story structure. The upper level and
roof are wood framed. The house has a high
gabled roof with two brick chimneys and six gable
dormers, three on the front and three on the back. The center dormers on the front and back of the house are larger than the outer dormers. The front porch runs the length of the building and is supported by square wooden posts. There is a second-story balcony above the porch. The dormers and the top portions of the main gable ends of the house are finished with fishscale wood shingles. There are Victorian style details on the second-story frieze, fascia boards, and support brackets around the dormers. The windows on the main level of the house are double-hung wood windows. The front dormers have tall, double-hung, two-over-two wood sash windows, while the rear dormers have simple casement windows. In the 1950s, a one-story addition was built onto northeast corner of the house. The addition has a gabled roof with board-and-batten siding. The main entrance to the ranch house is at the north end of the addition. Inside, on the first floor of the original house, there is a large
living room,
kitchen,
dining room, and
bathroom. The one-story addition houses a
sun porch, walk-in cooler,
mud-room, and a small bathroom. Upstairs there are four
bedrooms and a bathroom. • The original
barn, built sometime around 1888–1889, is the oldest structure on the ranch. The barn's footprint is by . It has a log-frame with a gable roof. The roof was originally covered with wood shingles, but at some point the shingles were replaced with
corrugated metal. The structure has vertical siding made up of random-width boards. The south side of the barn has a lean-to shed attached. The barn interior is open space with a dirt floor. The building is supported by by timber posts, resting on tuff-stone blocks. There are built-in
chicken coops and a storage area at the north end of the barn. The south end has a feed troughs and area for
saddles and
tack. • The
pump house was built next to Roba Creek about 1900. The footprint of the pump house is by . It is a simple wooden structure with wood framing, wood-plank floor, vertical wooden siding, and a gable roof covered with wooden shingles. • The
privy is located in the corral area, near the barn. It was built sometime around 1900. It is a simple by wooden structure with by rough-sawn vertical siding. It has a gable roof with a south facing door. • The historic
corrals and fences are located at the top of a hill, north of the ranch house and barn. The corral area includes wooden fences and
cattle chutes built in the late 1890s. Most fence posts are peeled juniper logs, approximately in diameter. The fences have four rough-sawn pine cross-rails, each wide. Rock cribs made of rough-cut logs filled with rocks are used to anchor and support fence lines. The ranch complex also includes three non-historic buildings: a vehicle and equipment storage building, a machine shop, and a new barn. All of these buildings were constructed in the 1980s. The vehicle and equipment storage building has a wood-frame sheathed in board-and-batten siding. It has a shallow gable roof covered wooden shingle. The machine shop is a wood-frame building with corrugated metal walls and sheet metal roof. Half of the front side of the building is open while the other half is enclosed with a roll-up door. The new barn is a long, gable-roof building with a wood-frame, vertical wooden siding, and corrugated metal roof. One of the barn's gable ends has large doors for easy access. == Location ==
