Sustainable Living Innovations, a Seattle tech firm, is constructing a 15-story, 112-unit house tower with factory-made panels preloaded with plumbing, electrical wiring and mechanical programs.

A prefabricated strategy is getting used on a a lot smaller scale elsewhere in Seattle: The Block Project is constructing micro photo voltaic houses for the homeless.

The hassle, by the nonprofit group Going through Homelessness, crafts panels in a workshop after which assembles them within the yards of house owners who’ve agreed to show over a part of their property to a 230-square-foot residence for somebody in want.
