Why Build Your Own Space?

Custom outbuildings cost $20,000–$60,000 from contractors. Prefab sheds are one-size-fits-all and can't be reconfigured. Converting garages reduces home value. The Flexosphere is a modular building system that adapts to any purpose — design it yourself, build it from standard lumber, and reconfigure it when your needs change.

Frequently Asked Questions

Anything — home office, art studio, music room, meditation retreat, guest house, workshop, gaming room, or whatever you need. The modular design means you can customize it for any purpose and reconfigure later.
The Flexosphere uses the same Thios modular standard as all our products, but it's not specialized for any single function. Think of it as the blank canvas — you choose the purpose and configure accordingly.
Yes. Because the modules are interchangeable, you can swap panels, add windows or doors, and reconfigure the interior. An office today can become a studio tomorrow.
Standard woodworking tools — circular saw, drill, measuring tape, level. No special skills required. The step-by-step handbook walks you through every cut and connection.
Materials typically run $3,000–$6,000 depending on your configuration, insulation choice, and local lumber prices. The build plans start at $29.

OPEN SOURCE HARDWARE


The Thiosphere™ SDK, the foundation to all our products, is open source hardware. In fact, all Thios products are. Specifically the CERN Open Hardware Licence Version 2 - Strongly Reciprocal.

That's a fancy way of saying that if you want to use our design, even for commercial purposes, you have to share your changes with everyone else.
