The Thios Construction System
One standardized panel geometry. Every module connects to every other. One system, infinite configurations.
Modular Geometry
Every panel follows the same connection standard — swap, stack, and reconfigure freely. Design once, build anything.
Hardware-Store Lumber
Standard 2×4s from any hardware store. No exotic materials, no proprietary parts, no vendor lock-in.
CERN Open Hardware v2
The same license CERN uses for particle detectors. Modify, share, sell — no permission needed.
3 Basic Tools
Circular saw, drill, measuring tape. If you can build a bookshelf, you can build a Thiosphere.
How It Works
Design Your Space
Use the free 3D configurator to pick a structure type and customize your layout. Get your exact bill of materials.
Get Quotes
