Domus Opus Est - The Work of Shelter Never Ends.
A Most Efficient Shape
We have formatted our world for cars, yet have little else to make use of all that shed we have given over to these machines. A Thiosphere™ is created to fill that void with a purpose and beauty that defines its bold and efficient design. It is Open Source Hardware that anyone can build and modify to their own needs. Thiosphere™ - Domus Opus Est, (The Work of Shelter Never Ends).
The Fewest Parts Make the Strongest Shed
One Thiosphere™ is made from the fewest number of parts possible, yet resulting in a strong, light and roomy, modular shed that only takes up 1/2 of a parking spot. It is flat packable and can be assembled with common tools. It is modular so you can create an endless number of sheds, from a simple shelter to a complex office. It is both functional and beautiful, and designed to be a second place for life to flourish - whatever, and wherever those requirements are.

The number two in Greek is written as "δύο" and pronounced with a soft "th" sound (thío), rather than the hard "d" one might expect. This "thio" prefix perfectly describes the dual-sphere design of the Thiosphere™, a second place for life.
