The house itself might be medieval, looking at the roof structure, but otherwise that doesn't look medieval in my eyes. If we forget the girl's clothes entirely (because they belong to Akiba) and only look at the furniture, I'd have said rococo, kind of simplified like from a more rustic area, not high society.
The walls look rather Middle-ages, possibly Tudor. But given the architectural limits of the time, I doubt a common(er) house would have a ceiling this high.
It's lovely, though. Someday I want to have a manor out in the countryside - Two stories, wooden floors and clay-brick walls.
Cruck Houses could get very tall, and we could suppose that as Euro buildings lasted a long time, once past the first few centuries --- providing they weren't destroyed by stupid people ( actually I just read the 16th/17th century cottage of a vile person, the first mayor of New York, a Thomas Willett, in Barley was destroyed in 1972 ) lasted through --- the kitchen area, could have been added in the 17th century, Dutch-style --- down to this present-day girl.

Such stupidities are not the preserve of the West: despite being so old ( if not so early as they maintain ) magnificent structures in China were pulled down with each change in government/dynasty --- not even because the new dynasty told them to -- which is why there is not so much antiquity as there should be.
