In Japan, room sizes are not measured in feet or meters, but in mats, based on multiples of the standardized tatami mats that were traditionally used to cover floors. They have fallen out of favour, but designer Shin Yamashita has reinvented them in a modern version that might just bring them back. Think Tatami meets Dror Benshetrit meets IKEA flatpack.
Cliff Kuang at Fast Company calls them "almost genius" but I would lose the "almost."
Imagine the minimalist interior; nothing but a series of mats that you fold up into tables, backrests, work surfaces and more. There is even wiring built in.
