This looks like a perfect alternative for you, if you aren't into spending time in vacation houses, but still wish to enjoy the benefit of enjoying nature and having a roof over your head at the same time.
You can set it up anywhere you like - on a lovely hillside, on an ocean beach or even in a large garden, however it's not on wheels, so you can't transport it all the time. Find a nice spot and settle down as the hut comes with a raft foundation, the same type that's used when building ordinary homes.
While minimalistic in its philosophy, it offers exactly what you need to spend the night in a pleasant way. The interior is quite compact at 9m2, but there's also the porch and the high shed roof that give plenty of comfort to even for 3–4 people. The large window at the entrance that was originally created to be a shop's sliding door now offers extra light, next to another smaller window.
All of the wood used for the hut is sourced from Japan, such as Japanese cypress veneer. Inspired by the traditional art of Japanese shipbuilding, where builders burn cedar wood to increase its strength and add an oil stain finish, the outer walls are given enhanced antiseptic properties and durability by applying burned hardwood cladding, developers wrote in the Muji Hut description. Once inside, the walls were left for you to decorate and use them they way you like it.
In Japan only, the huts will be available for purchase in autumn 2017 for ¥3,000,000 (cca $27,000).
