OxygenHaus

What OxygenHaus does

OxygenHaus (legal name "Oxygen Haus") designs and manufactures factory-built, off-grid accessory dwelling units (ADUs) sold direct-to-consumer to US homeowners, real estate investors, and families seeking additional residential or workspace square footage. The company's product line currently consists of two SKUs: the Model O-1, a 160 sq ft studio starting at $49,997, and the Model O-2 (also branded as the OxygenHaus XL), a 320 sq ft full living studio starting at $99,997. Customers reserve build slots through oxygenhaus.com with fully refundable deposits ($99 or $199), with the balance due on delivery and installation.

The underlying technical proposition is an integrated off-grid systems stack built around a ModulBox structural core and WPC exterior panels. Each unit combines atmospheric water generation, roof-integrated solar with lithium battery storage, and incinerator plumbing designed to eliminate dependence on municipal water, sewer, and grid power. A mobile interface allows owners to control lighting, climate, security, and water production, while embedded sensors drive a self-diagnostic system that flags plumbing micro-leaks, solar voltage drops, and HEPA filter saturation via push notifications. All units are manufactured in Tucson, Arizona and shipped nationwide.

The business model is a one-time unit sale with a low-friction DTC reservation funnel. Go-to-market is exclusively through the company's own e-commerce website supported by a news/blog section, social media presence, and a marketing content partnership with Marketing Circle Stone Capital. The company has disclosed plans to grow both organically (expanded product line, industry conference participation at IMN Manufactured Housing 2026) and inorganically (an identified but unnamed acquisition target). OxygenHaus is privately held with no disclosed revenue, funding history, headcount, or institutional ownership.
