This house in Tokyo by Sou Fukimoto Architects, known as House NA, stands out with its modern and transparent style. The interior of the residence has hardly any walls. The house boasts large glass windows for plenty of daylight, but the downside is a lack of privacy.
The three-story edifice features various levels of living space within the segmented structure that's great to just hang out on, as if you were perched atop a tree branch. House NA is the modern interpretation of an adult treehouse for permanent residence.
