Why This Matters
🔓
Fork it, Hack it, Sell it
Open Source means you can use it commercially, modify it freely, and share your improvements.
🛠️
Hardware-store Parts Only
Built from standard lumber and hardware. No exotic materials or special tools required.
💰
Your $29 Funds Prototypes
When you buy a handbook, you're literally funding the next open-source prototype we build.
📐
Full CAD + Cut Lists Included
Every handbook includes complete 3D models, 2D drawings, and precise cut lists for zero waste.

We're Sequencing From Simple to Complex
🏕️
Why Sauna First
Fewest parts, rustic aesthetic, forgiving construction. Perfect for learning manufacturing without needing precision. Your handbook purchase funds us getting good enough to build the complex stuff right.
🏃♂️
Crawl → Walk → Run
Sauna (crawl): Basic structure, forgiving tolerances
Greenhouse (walk): More complex, tighter fits
Office/Other (run): Full complexity, zero margin for error
🌱
Why Greenhouse Last
Most parts, tightest tolerances, zero margin for error. Water leaks destroy everything. We're building capability first before tackling the most demanding builds.
🎯
Current Focus: Saunosphere
We're building the simplest, most forgiving structure first. This gets us good at manufacturing while giving you something valuable to build.
