Cosmic Buildingsβ Cosmic One combines a compact footprint with a full kitchen, bathroom, connected home controls and roof-mounted solar and battery storage. The featured Studio layout measures 380 sq ft (35.3 sq m), but it has an open living area rather than a dedicated bedroomβa key distinction for anyone considering it as a full-time home or guest retreat.
What is the Cosmic One?
The Cosmic One is a prefabricated micro house by Cosmic Buildings. New Atlas reported on the home on July 8, 2024, describing several layouts, including the 380 sq ft Studio and a larger, two-bedroom version measuring 750 sq ft (almost 70 sq m). The report does not establish whether those configurations are still offered.
Its design pairs a wood-and-steel exterior with a distinctive roofline, integrated solar panels, a small deck and sliding glass door access. Inside, the emphasis is on recognizable residential features rather than a bare-bones shelter: cooking and cleaning appliances, a bathroom, storage and connected controls.
How the layouts differ
| Layout described | Reported area | Bedroom arrangement | What to consider |
|---|---|---|---|
| Studio | 380 sq ft (35.3 sq m), as reported by New Atlas in 2024 | Open living area and office; no dedicated bedroom in the pictured configuration | Sleeping arrangements would need to use the open space. New Atlas suggested a sofa bed or Murphy bed, but did not identify either as a supplied feature. |
| Separate-bedroom model | Not stated by New Atlas | Separate bedroom | Confirm the current floor plan and area with the manufacturer. |
| Two-bedroom version | 750 sq ft (almost 70 sq m), as reported by New Atlas in 2024 | Two bedrooms | The additional area and rooms may suit households needing more privacy; current configuration details are not established. |
These are configurations described in the July 2024 report, not a confirmation of todayβs catalog. For a construction decision, compare the current plans, usable storage, circulation space and bedroom separationβnot just the headline floor area.

What is known about the solar and battery system?
New Atlas described the roof-based solar panel and battery setup as standard. Additional batteries and greywater filtration were reported as optional upgrades for buyers seeking off-grid operation. However, the article gives no solar-panel rating, battery capacity, energy-production estimate or measured period of off-grid operation.
Those missing specifications matter: the presence of panels and batteries alone does not show whether a home can reliably run its appliances without grid power. Before evaluating off-grid suitability, ask for the systemβs rated output and usable storage, the loads it is designed to serve, and the details and capacity of any greywater treatment. Also clarify what happens during prolonged low-sun conditions and whether backup power is part of the current offering.
