Mr. Kammerer was a media executive and founder of the television advertising company ITN Networks. He was also an avid fan of the Old West, as imagined by novelists like Louis L'Amour and Zane Grey, according to his son. The property replicates many of the features of a frontier town you might see John Wayne mosey through. There is a building designed like a chapel, horse stalls and a riding ring--and even a space meant to look like general store.
The inspiration for the compound, known as 'Rancho Alegre,' came when Mr. Kammerer found the remains of an old chapel on the property, according to his son. Though the building was beyond repair, Mr. Kammerer used the idea of having a chapel-like structure on the property to anchor the 'town.' A view of the new building is shown. It serves as a media room and entertaining space.
The main home on the property is roughly 13,400 square feet. It has five bedroom suites, five full bathrooms and two half baths. Across all buildings on the property, there is more than 24,600 square feet of space, 13 bedrooms, 11 full bathrooms and four partial baths, according to the listing. The living room, with a 20-foot-tall ceiling, and wide-plank oak flooring, is shown.
Mr. Kammerer was an avid collector of art and memorabilia. His study, shown here, included a collection of cowboy riding chaps. Most of his personal items will not convey in the sale, his son said, but many of the furnishings will stay with the home.
The conference room, shown here, was designed in part by artist Cathy Smith, who created the costumes for the film 'Dances with Wolves.' The room is adorned with re-creations of Plains Indian garb and quotes from Native American chiefs Mr. Kammerer admired are written on the walls.
The compound features several hallmarks of traditional Pueblo-style homes, like adobe walls and boveda-style ceilings, an arched structure made with brick. The flooring in the sunroom, shown here, is tumbled travertine and features a black granite inset with a pattern of American eagle feathers.
La tinaja de Miguel, or 'Michael's watering hole' is the name Mr. Kammerer's family has given this indoor bar , which features a kiva fireplace and a leather-covered countertop.
The master bathroom is inspired by the architecture of Chaco Canyon. Located in northwestern New Mexico, the area is a significant cultural site for the ancestral Pueblo peoples who populated the American Southwest, according to the National Park Service. The stonework disguises two matching shower heads, shown at center. The room measures 20 feet by 15 feet, according to the listing agents' website.
The 'Chaco shower' also includes a kiva fireplace and bathtub.
The kitchen, with boveda ceiling, is shown. The home also includes a wine cellar, a library and 18 fireplaces in total.
The property also includes a large stone watchtower that overlooks the grounds. It measures about 700 feet, Mr. Kammerer's son said, and was nicknamed the 'margarita deck,' because guests would often sit at the top for cocktails. But at that height, 'you don't want to have more than one,' he joked.
Mr. Kammerer was an amateur team roper. The rodeo event involves two 'ropers' attempting to lasso a steer. A riding area and some of the horse facilities on the property are shown. There are six 'casita' horse sheds and a total of 12 horse stalls with paddocks.
The home was listed for $12.9 million in March 2008. In December 2011 the price was lowered to $9.9 million. It is currently listed for $7.5 million. 'We're trying to listen to what the market is telling us,' the younger Mr. Kammerer said about the new price. Ray Rush and Tim Van Camp of Sotheby's International Realty share the listing.
