House K may look small from the street, but this intelligent design is large enough to house two families. With a maximum width of a mere seven feet, House K stretches into the sky to create additional square footage. Designed by Hiroyuki Shinozaki Architects, this home achieves a comfortable living space by utilizing towers and space-saving staircases. Two thirty foot towers are connected by a central hall. Each tower holds the living areas for one family, allowing for privacy as well as connectivity.

I appreciate this housing concept: two distinct but coupled spaces allow for an extended family to live in sync. The combination of wood and concrete is also lovely: the wood evokes the memory of traditional Japanese homes, while the concrete is distinctly modern. House K's thoughtful design is a solution I hope we can see more of in multi-family housing.
