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.

Sized to How You'll Use It

Every size, every use

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.
