Three-story tiny house which fits in the footprint of a parking space. With a floor for working, another for sleeping, and a greenhouse on the top, the Tikku house is designed to replace a city’s parking spots with living space. Made of prefabricated CLT cross-laminated timber spatial modules. “This could not be done with concrete,” he says. “It would become too heavy, and it would sink.” By using cross-laminated timber, which is five times lighter than concrete, it’s possible to install the tiny house without a foundation. A sandbox on the bottom balances the building; Casagrande says that because the material is flexible, it also performs better than concrete in earthquakes. It’s possible to make even taller tiny houses if they are clustered together to provide more support.
The construction process is fast on site: The modules can be built in a factory, and the whole house can be installed in a parking lot overnight. “I would like to emphasize how easy it was,” Casagrande says. “It’s almost ridiculous. Usually, building a house is really a pain in the ass, and it takes so much effort . . . In this case, it just popped up.”
The modules can be customized for different needs; the prototype has a floor for working, another for sleeping, and a greenhouse on the top. “I want to mass-produce Tikkus in different combinations,” says Casagrande. “It’s very easy to make very different modules. You can choose what is the best combination for you: If you want two floors for living, or a kitchen unit, or a sauna, or a place for yoga or a place for a small shop downstairs, and so on.”
