The technology is here now. This house is a boring square cracker box, which you would expect from Habitat for Humanity and a proof of concept. However, the freedom of 3-D printing allows you to make almost any shape that you can imagine that is physically possible.
Modern houses are shaped the way they are because of ease of construction and cost effectiveness, mostly.
How can we use the new freedom offered by the technology to make entirely new structures that take advantage of the freedom of form and reduced waste in construction?
I’m thinking of things like amazing windows and passive climate control structures inspired by how termites manage the climate in their mounds. Does anyone have any interesting forms or shapes they’d make?
I think 3D printing walls could potentially make isolation cheaper by building it directly into the structure, similar to how wasps build their hives.
I am less convinced about funny shapes as in the end you still want your furniture etc. to fit, and I know from painful experience that renovating an old house with walls that aren’t in a 90° angle can be a real PITA.
