This property is truly unique, both in its history and its luxurious features. Originally inspired by the natural beauty of the Indiana Dunes, the legacy of Senator Paul Douglas, who played a crucial role in preserving the area as a national treasure, continues to resonate. His dedication led to the establishment of the Indiana Dunes State Park, now known as the Indiana Dunes National Park. The new cabin, built in 2011 by another distinguished Illinois Senator and Judge, honors Senator Douglas's efforts with both its location and its high-end construction. Situated atop a dune with views of Lake Michigan, the cabin boasts a variety of upscale features. These include Poggenpohl cabinets, Miele appliances, an onyx main bathroom, a steam shower, a catering kitchen, a fire suppression system, geothermal HVAC, and an elevator, all contributing to a blend of luxury and structural integrity. This property invites new visionaries to continue its legacy, adding their own chapters to its storied history while enjoying the unparalleled beauty and tranquility of the Indiana Dunes.
