So you can work from it, live in it, rent it, or build a new separate unit.

We handle everything, from permits to construction.

It comes in three sizes, with tones of design options.

How it works

Configure your Cosmic ONE

Generate more energy than Cosmic ONE requires and use it to offset the power consumption of your main home and charge your EV car.

Site visit

Run more power-hungry appliances like HVACs and induction cooktops during a grid outage or transition to completely off-grid living.

All-in contract review

Non-toxic interior materials and finishes boost indoor air quality by reducing or eliminating the off-gassing of volatile organic compounds (VOCs)

Construction

Increase the water availability in your home by recycling wastewater and reused for all non-potable needs inside the home, in the garden, or for the pool.

Move-in

Cosmic ONE is factory fabricated with robust insulation keeping our homes comfortable and quiet while reducing energy.

We believe in a future where more people have access to modern and healthy homes.

Whether you’re getting way out there in the National Forest, or sticking closer to home at your favorite campsite, we’re building products and experiences to help you get outside
