Dezeen just released an article featuring the Cosmic ADU, a Silicon Valley Startup "self-powered" home designed to be self-sustaining and potentially add electricity back into your property via the attached solar panels.
Cosmic's price tag is a little heftier than Footholds, with a studio starting at $190,000 and a one-bedroom model starting at $370,000.
There are two options with the Cosmic solar panels, too: you can purchase them directly, or Cosmic can retain ownership of them (and, therefore, the power it produces.) Check with Northwestern Energy regarding their energy purchase policies before adding a solar option to your property.
This product, unlike Foothold's, does not arrive on-site constructed but instead in sections like a modular home. The total shipping weight of this home is only 600 pounds, facilitating nationwide delivery! This home-style will still require an on-site contractor to complete the build.
This home is designed to function on a pin and pier foundation, allowing the end-user the flexibility to skip a traditional foundation and expand the location installation options. Further, this product was designed to function as an ADU addition, stand-alone property, or simply a home-office extension.
