Salt Castles

Could you live in a house made entirely of salt? In an increasingly hot, dry world, salt could very well become the building material we need to address climate challenges.

Salt Castles imagines a future in which technology helps instead of harms. When drinking water becomes scarce and desalination common, 3D printing with the extracted minerals could forge a new connection between excess and care. Salt structures, born from crisis, could store energy like simple sodium batteries.

By combining 3D printing with the hidden potential of waste minerals, Salt Castles challenges architects to see raw materials and waste as equally valuable. Living in a Salt Castle doesn’t mean hiding from the world. It means living with change, the passage of time, energy alternatives, and the present moment on earth.
