Eighteen months ago this was a sketch on graph paper. Today you can buy the complete build guide and start cutting lumber this weekend.
The Whole Thiosphere Handbook is a 200+ page PDF covering every step from raw materials to a finished modular structure. Three pricing tiers, one philosophy: well-designed spaces should be accessible to everyone.
What Changed Since January
We announced the handbook on January 1st. Since then:
- The 3D Configurator launched. You can now design your layout in the browser, see the bill of materials, and even get quotes from local builders. Try it at thios.co/configurator.
- The vendor quote pipeline went live. Design your sphere, click "Get Quotes," and local suppliers receive your exact material list. No phone tag. No guessing.
- 10 languages. The entire platform now supports English, German, Spanish, French, Italian, Japanese, Dutch, Polish, Portuguese, and Swedish.
- The blog hit 37 posts. From sauna health research to first-principles design thinking. All free, all public.
None of that changes what the handbook is. It is still a PDF with plans. But it changes what the handbook means — it is your entry point into an ecosystem that did not exist six months ago.
The Three Tiers
Standard ($29) — The complete PDF. Cut lists, assembly sequence, material specs, expert tips. Everything you need to build.
Lifetime ($79) — Everything in Standard, plus lifetime updates as we improve the design, plus CAD files (STEP format) for customization. This is the one most people pick.
Founders ($299) — Everything in Lifetime, plus every future handbook we publish (Saunosphere, Ergosphere, Immosphere, Agrosphere), plus a founder badge, plus direct access to the team. This is for people who believe in what we are building.
All three tiers include community access and commercial use rights under CERN-OHL-S-2.0.
Who This Is For
DIY builders who want a backyard office, sauna, studio, or storage shed — and want to build it themselves with standard lumber from any hardware store.
Contractors and builders looking for a modular system they can manufacture and sell. The open-source license means you keep 100% of what you charge your customers.
People who want a sauna but think $80,000 is absurd. The Saunosphere variant builds for under $5,000 in materials. The handbook shows you how.
What Happens After You Buy
- Instant PDF download via email
- Discord community invite
- Access to the 3D configurator (free for everyone, but handbook buyers get the full context)
- Email support from the team
Lifetime and Founders members also get CAD files and automatic updates as the design evolves.
The Money Goes Somewhere
Every handbook sale funds the next prototype. We are a bootstrapped company with zero external funding. Your $29 literally pays for the lumber in our next test build.
This is not a side project with a donation button. It is a business model where early customers fund better products for future customers. The handbook is your angel investment into a platform that wants to make well-designed spaces accessible worldwide.
