Casagrande Laboratory, a multidisciplinary architecture practice based in Helsinki, Finland, has completed Tikku, a three-story micro-apartment building, in a square there. With a footprint of just 8.2 inches by 16.4 inches, or about the size of a single parking space, Tikku is a bare-bones sustainable building constructed from cross-laminated timber (CLT) “spatial modules” that can be erected overnight. Touted as a “safe-house for neo-archaic biourbanism,” Tikku offers a minimum of creatures comforts… Everything else—showers, laundry, and food, to name a few—can be found outside the home, eliminating the need for plumbing and a kitchen. Still, Tikku acts as a private refuge in the middle of any city. And because it’s made from a material, CLT, that is five times lighter than reinforced concrete, it can be upped and moved at a moment’s notice.
