Called "Keret House," the home was designed by Jakub Szczęsny and is under construction in Warsaw, Poland. At its narrowest point the house will only be 28 inches wide, which as Fast Code Design notes, "is skinner than the average doorway." In fact, the home is so narrow that it is officially classifed as an "art installation" because it doesn't meet Polish building codes.
The home is slated for completion in December and will function both as Keret's work and living space. In addition to be incredibly narrow, the home will also include off-the-grid plumbing and entry stairs that fold inside the home to become part of the first floor.
Could you live in a home this narrow? While impressed by this feat of modern architecture, living in such a small space would drive me nuts.
