As 3D printing homes becomes more common, could we finally see residential architectures break out of the same old box shapes" If the Fibonacci House by Twente Additive Manufacturing is any indication, this technology could open up a whole new world of organic architecture, introducing cool and creative new designs.

The Fibonacci House is a tiny 3D-printed house that gets its name by following the famous Fibonacci sequence in its spiral form. Currently in progress near the company’s headquarters in British Columbia, Canada, the house was built with their Laticrete 3D Printing Mortar M68 concrete printers, boasting both a compact footprint and enough head room for a loft in order to sleep four people.

To build it, the company used two main classes of printing mortar: a slow-drying one that’s strong enough to support subsequent layers above it before fully curing, and another one with a drying accelerant added so it can dry faster. The second type is kind of like a concrete-based glue, allowing Twente to print overhanging structures and bridge gaps between parts, all of which were printed off-site in a controlled environment where the printers can be protected and work 24/7. The house was divided into 20 parts and shipped to the location, where the pieces were assembled. The walls aren’t load-bearing in their own right, but the system includes columns and shear walls to hold up the exterior. Each piece is dual-layered for thermal insulation. The house...
