"The tallest residential house in North America isn’t in some big, metropolitan center. Rather, it is found at the base of Thumb Butte in Prescott, Arizona. If the looming, 6,000-foot tall volcanic plug isn’t weird enough for you, then maybe the Falcon Nest will be," the Arizona Oddities reports.

"Towering above the Prescott National Forest at 124 feet, the Falcon Nest is a postmodern conglomeration of rectangular geometry, floor-to-ceiling windows and panoramic views of northern Arizona. Boasting 10 stories and a comfortable 6,200 square footage, this is far from average — especially in Prescott.Its name pays homage to the Peregrine falcons that nest on the slopes of Thumb Butte.

"Some of its notable features include a 2,000-square foot solarium at its middle, extending out above the tops of juniper and Ponderosa pine trees below. The solarium, completely enclosed in glass panels, contains two bedrooms, two baths, the kitchen, a living room and, of course, breathtaking views. From its windows on a clear day one could easily point out the San Francisco Peaks, Bill Williams mountain, and the surrounding Sierra Prieta mountain range. Furthermore, the Falcon Nest boasts some green features like passive heating and cooling capabilities, solar technology and a hydraulic elevator that provides transport from the ground level to the sixth. What it lacks in carbon footprint, it makes up for in innovation.

"Falcon Nest is a detached residence in Prescott, Arizona, that is the tallest single family home in North America at 124 feet (38 m). Its name is attributed to its resemblance to a large mountainside bird's nest and the peregrine falcons that inhabit the area. It is located in Yavapai County, approximately a two-hour drive northwest of Arizona's capitol, Phoenix.

"The home is 6,200 square feet (580 m2) in size and was designed by Phoenix architect Sukumar Pal for himself. It was built in 1994 at a cost of approximately $3.5 million and is located on the slopes of Thumb Butte, a prominent geographical feature of the Sierra Prieta mountain range in the Prescott National Forest and a popular hiking venue with trails that ascend and encircle the butte,[4] a 6,514-foot (1,985 m) volcanic plug.

"Although the house is relatively large, its foundation is a square measuring 24 by 24 feet (7.3 m × 7.3 m); its size is spread vertically over ten stories. Much of the main floor extends out from the core of the structure similar to large fully enclosed balconies on four sides. This 2,000-square-foot (190 m2) area is built as a solarium with glass walls and roof.[9] It includes two bedrooms, two bathrooms, a kitchen, and a great room. A third bedroom and two additional bathrooms are on other levels.[10] The house is 124 feet (38 m) in height." (Wikipedia)

"Constructed at the the slope of Prescott, Arizona’s Thumb Butte, the house that Phoenix architect Sukumar Pal built for his own family soars to 124 feet and views stretching over 120 miles to mountain ranges in every direction. Also one of the most futuristic homes in the world, Pal built Falcon Crest in 1994 to be energy efficient while still maximizing views with glass walls and ceilings.

"Encompassing 10 floors at different levels and angles above a small 24’ by 24’ footprint, most of the living space is found in the home’s four wings that flare out near the upper level creating a residence of 6,200 square feet with three bedrooms, four full baths, 2,000-square-foot solarium, open kitchen and great room," the Daily Advertiser reports.

"Having won multiple awards for his specialization in designing energy-efficient homes, the Pal residence has won four residential architecture world records including top honors for its unconventional heating and cooling systems that utilize passive solar for winter heat and micro climate and convective cooling in the summer."

"There are benefits to building a tower with such a small footprint too: Taxes are considerably lower; views become more expansive across each level; and the height increases air movement from ground level up through to the top of the tower.

"With surroundings ideal for promoting holistic health, green living and mindfulness, Falcon Nest is equipped with solar panels and boasts unique and alternative power, heating and cooling sources," the House Beautiful reports.

"Phoenix architect Sukumar Pal built the energy efficient Falcon Nest property near Thumb Butte in 1994 for his own family, while making every effort to maximise views with glass walls and ceilings."
