1 the pattern of Japanese old school ryokan design is
wooden floors, and panels.
at times even the ceilings are covered.
2 living rooms are covered with tatami mats.
3 technologic advancements are incorporated into the house:
robotic toilets with bides, water temperature led control panels
4 finally the house will typically have a "greenery" area with elements of
vegetation, rocks and some grass
this gives out a pleasant nature outdoorsy vibe
some limitation will be the lower durability of the floors, which IG is why Japanese take off their shoes when
entering a house.
the design is not complimented by framed pictures, but by wall scrolls or tapestries.
