This house in Hateno Village:
has a visible niche on the left with a couple of little windows, but inside the house there is no visible access to it. Also, inside the house there is a mezzanine which works as the upper floor, but the corresponding ground floor part is inaccessible.
Notice that:
I know this house can be bought and furnished, but doing so does not (apparently) change the accessibility of these spaces.
Is there any way to access these parts of the house or at least see if there's anything inside them?

From a GameFAQs thread, which also confirmed lack of entry.
From another GameFAQs thread, where multiple players explicitly indicate the lack of ability to enter "Link's shack":
