Dubbed the "Skysphere," his getaway is a stunning steel tower surrounded on all sides by glass.
The Skysphere makes an ultra-futuristic statement in a field ringed by trees. The tower's lighting and security system can be controlled using an app Williams built for Android.
"I tried to keep every aspect of the design original," Williams told Business Insider in an email. "I do live near a wind turbine farm, so maybe I got some inspiration from those?"
Williams shared some photos from the tower construction with Business Insider.
