Located in the deserts of the Coachella Valley near Palm Springs, California, this massive modern mansion was originally constructed by developer Duane Hagadone. Built on a grand scale with a plethora of technological bells and whistles, the home has been recently listed for $49.5 million.
Duane Hagadone purchased the California property in 2007, having made a fortune in real estate development and newspaper publishing. Hagadone is most well known for building the Coeur d’Alene Golf & Spa Resort in Coeur d’Alene, Idaho, which quickly became a tourism hotspot.

The home is built on a ridge at the center of a nearly 8 acre property. The home itself is absolutely massive, coming in at around 32,000 square feet with seven bedrooms and twelve bathrooms.

The home was designed by architect Guy Dreier and has a unique, sculptured look. The walls are highly asymmetrical, as if they were rough hewn out of the desert stone. Complementing this is the Indian panther slate that covers much of the exterior of the home.

By contrast to the cavernous, sculptured design of the walls, the home also features many glass and metal elements. There are 16 fully retractable glass walls throughout the home. The design also incorporates a huge amount of metal finishes, such as a number of titanium fireplaces. The roof was made using around 55,000 pounds of copper.

On top of all this, the home is replete with amenities. There is a shark tank, as well as several large fish tanks. There is a separate office and garage apart from the main residence. Much of the home’s lighting and other features are operated automatically via smart-home technology.
