👋 New to Thiosphere™?
Welcome! We are building an open-source, modular shelter system that anyone can build.
But we're doing it differently. We are Building in Public using a strategic "Crawl, Walk, Run" roadmap. Instead of selling you a finished prefab box, we give you the plans (The Handbook) to build it yourself, locally.
✓ Open Source | ✓ Educational | ✓ Community Owned
🚀 The Strategy: Crawl, Walk, Run
We are sequencing our products to fund development and build capability step-by-step:
CRAWL
Saunosphere™
Rustic designs, fewer parts
WALK
Ergo/Immosphere™
Tight integration, refined
finishes
RUN
Agrosphere™
Precision & high complexity
Your purchase of a handbook today funds the next prototype tomorrow.

100% Open Source
All designs are open. Modify them. Improve them. Share them. Sell what you build. Full commercial rights.
Modular System
Start with one module. Add more later. Mix and match. Build exactly what you need, when you need it.
Actually Affordable
No markup for "assembly required." You do the work, you save the money. Typical build: $2,000-$5,000 in materials.
Sustainable
Designed for longevity. Repairable. Recyclable. No planned obsolescence. Built to last decades.
🎯 Which Product Is Right for You?
Answer these quick questions to find your perfect match:
What's your primary use case?
❓ Quick Answers
Do I need construction experience?
No. If you can follow IKEA instructions and use basic tools (drill, saw, level), you can build this.
How long does it take to build?
Most builds take 2-4 weekends for one person. Faster with help. Take your time—there's no rush.
What if I get stuck?
Join our Discord community. Ask questions. Share photos. Get help from builders who've been there.
Can I customize the design?
Absolutely. That's the whole point. Licensed under CERN-OHL-S-2.0 (strong reciprocity), you're free to modify, improve, and even sell what you build—as long as you share improvements back. Make it yours.
Do you ship materials?
We now offer precision MDF templates that ship to you! For raw materials, you source locally (lumber yard, hardware store) to keep costs down and support local businesses. Order templates here →
