Engineered for Strength, Designed for Immersion
The Tetra Dome Series utilizes a geodesic triangular framework to create a resilient, self-supporting structure. Unlike conventional buildings that rely on vertical walls and right angles, this shape distributes weight evenly across the frame. Wind, snow, and seismic loads are addressed in the engineering for your site, with stamped documentation available for permitting—offering a space built to endure while embracing breathtaking surroundings.

- Maximizes structural integrity while using minimal materials.
- Eliminates weak points by ensuring even weight distribution.
- Engineered for the wind, snow, and seismic loads at your site with ease.

Our clients say
“After years of dreaming about a tiny home, we finally pulled the trigger on a 30′ dome from The Dome House. We went with the hybrid model so we could have views and privacy where we wanted them. … Every time someone visits, they say, ‘I had no idea a dome could feel like this!’ We love it.”

FAQs
How big is the 26 ft Tetra Hybrid dome?
It measures 26.25 ft across and 14.5 ft high, with about 541 ft² of floor area. The listed capacity is 4–10 people.
What sizes does the Tetra Hybrid dome kit come in?
5 sizes: 16, 20, 23, 26, and 30 ft. Each size has its own page with its full specifications, and every kit is made to order.
What makes the Tetra Hybrid Dome different from other dome kits?
The Tetra Hybrid Dome lets you combine tempered glass panels with wood-grade aluminum insulated panels, giving you the best of both worlds—panoramic views where you want them, and privacy or thermal control where you need it.
Can I choose where the glass and aluminum panels go?
Yes. At The Dome House, we build each Tetra Hybrid Dome to order. You can pick which parts of the dome stay fully transparent and which are solid. Want privacy in the back and views up front? Easy. Need more insulation on the north side? We can make that happen.
What materials are used in the Tetra Hybrid Dome?
The frame is made from aluminum structural struts, not PVC or wood. Panels are a mix of double-pane tempered glass and insulated aluminum composite. These aren’t tent materials—they’re chosen for a permanent structure and look great doing it.
Is insulation included?
We offer rigid insulation panel upgrades for the aluminum sections, which most customers choose. These panels help regulate indoor temperature and make the dome comfortable for year-round use—even in colder climates.
What sizes does the Tetra Hybrid Dome come in?
Five standard sizes from 16 ft to 30 ft in diameter, with custom sizes on request. Common picks include 20 ft, 23 ft, and 30 ft—especially for short-term rentals, backyard studios, or tiny homes. We’ll help you size it based on your intended use.
Is the dome weatherproof?
Panels are sealed into the frame with gaskets and fasteners, and the kit is four-seasons ready. Wind and snow loads are addressed in the engineering for your site, with stamped engineering documents available for permitting.
Can I use this dome as a tiny home or Airbnb?
Absolutely. In fact, that’s one of the most popular uses for the Tetra Hybrid Dome. Many clients build them out with plumbing, electricity, and finishes for glamping stays, tiny homes, or eco resort units.
What kind of foundation does this dome require?
Most customers choose a pier foundation with a raised wood deck. It’s simple, clean, and works great for insulation and water runoff. Concrete slabs are also possible if preferred. We’ll include foundation guidelines and can provide stamped engineering docs on request.
How long does it take to build?
With a local crew or contractor, the dome shell typically goes up in 3–5 days. Interior finish-out varies depending on how detailed you go. All panels arrive pre-cut, numbered, and ready to install with our guide.
Can I add ventilation or HVAC?
Yes. We offer ventilation upgrades, including operable windows, exhaust fan cutouts, and HVAC prep options. Many customers also install mini splits, solar-powered fans, or wood stoves depending on their climate and power setup.
What colors or finishes can I choose for the solid panels?
The wood-grade aluminum panels come in a range of finish options—wood tones, matte black, or neutral hues. If you’re looking to match the environment or brand your dome for a resort, we can work with you on color selection.
How is the Tetra Hybrid Dome shipped?
The entire kit ships flat-packed on a pallet or crate and includes all necessary framing components, panels, and fasteners. You’ll also receive a detailed instruction guide. Free shipping to the contiguous U.S.: freight is included in the kit price. Alaska, Hawaii, and international delivery are quoted separately.
