This model of a free-form compression-only vault has been build using rapid prototyping. It stands just by gravity and friction. It is part of a research project of the BLOCK Research Group at the ETH Zurich. Two publications describe details about the structural models and the design process.

Form and force diagrams in plane, the force distribution in the network, and the form of the network in 3d.
The form-finding process is based on TNA, a method developed by Philippe Block.

This is great! thanks.
That's a really great demonstration of the physics of such surfaces. How did you go about assembling the pieces? Did you make a small formwork and build on top of it?
Indeed, we milled a formwork from foam. Check out the two papers about the design process and the model mentioned above for details.
Masonry construction can give you a n awesome looking house. It is not only decorative but also great for durability. Know more from here-

Great read on masonry! I've starting reading the other things you have been putting out on the web!
