Houses like this in Austin are absolutely no surprise to me. They've been building fugly buildings in Austin for about a decade now. You have a mix of throwback 60s designs, postmodernism and McMansions. Then there's buildings clad in like squares of different materials. Bricks with corrugated tin squares then into faux wood siding, and they're all painted different colors like they ran out of materials, but it was on purpose. All of them are eye sores, especially the McMansions with huge fishbowl windows painted gaudy colors like hot pink, bright orange and white.
They don't grind them flat, they stucco over them to give a smooth surface. To grind a huge wall flat would create tons of concrete dust and weaken the structure since you'd have to remove around 50% of the material making up the wall.
I predict these houses will start falling apart in less than 10 years. Aerated 3D printed concrete is going to soak up moisture like a sponge and cause mold problems. And the first time it freezes, all of that soaked in water is going to blow the concrete apart.
For developments like this they usually grind them flat and they only print the first floor.
