Immobile and invariably on-grid, apartments are the antithesis of a couple of cherished tiny house aspirations. What they do share is a common size range, and we’ve always thought that a well-designed apartment can teach valuable lessons on how to lay out a sub-400-square-foot interior. This one’s in Wroclaw, Poland, created by architectural firm 3XA of that city. The approximately square, 312-square-foot area has been divided into two halves, each with two sections. The more open half holds a living area in one corner and a home office space in the other. In the other half, a wall divides the kitchen/dining area from an entry hall which passes next to the bathroom and under a sleeping loft. The stairs up to the loft double as the office’s bookshelf. It’s a simple, smart way to separate functional spaces without cramping anything, and although it might not work in a more rectangular THOW it would fit just fine in a small cabin. 3XA’s white-and-waferboard interior deco gives a modern style to what’s in fact a 19th century building; if it appeals to you, be sure to check out their loftless apartment at http://3xa.pl/wroclawski-apartament/.
