Geodesic Dome Kit Sizes and Dimensions
Five standard sizes, two kit systems. Every size below is available as a Tetra Glass or Tetra Hybrid build — same frame geometry, your choice of full glass or glass plus insulated panels. Custom sizes are available on request.
Five standard sizes
| Size | Diameter | Height | Floor Area | Sleeps |
|---|---|---|---|---|
| 16 ft | 16.4 ft | 10.5 ft | 215 ft² | 4–8 people |
| 20 ft | 19.7 ft | 11.5 ft | 312 ft² | 4–8 people |
| 23 ft | 23.0 ft | 13.8 ft | 420 ft² | 4–8 people |
| 26 ft | 26.25 ft | 14.5 ft | 541 ft² | 4–10 people |
| 30 ft | 29.5 ft | 19.7 ft | 689 ft² | 4–8 people |
Both kit systems share these dimensions. Heights are catalog values for planning; interior program — lofts, kitchens, bathrooms — foundation footprint, and materials are confirmed against your location and engineering during quoting.
Every size, every use
Sized to How You'll Use It
The same frame geometry runs from a single guest suite to a full-time home. What each size holds — sleeping, living, kitchen, bath — depends on your layout, site, and local rules, so we size it with you rather than by rule of thumb.
- Luxury rentals and glamping units
- Dome homes and modern living pods
- Backyard sanctuaries — garden office, spa, reading room
- Showrooms and event spaces
- Wellness and creative studios
- Off-grid and eco-resort units
