Details:

Currently there's a (bug? unintended feature?) that prevents furniture to get close to the wall only in houses located in The Goblet.

Using a Potted Spider Plant as example, if you try to move the potted plant close to the wall it wont let you (1, 2), the same issue can be observed by using pretty much any furniture, be it tables, chairs, bookshelves, etc.

But as you can see here the issue is absent in houses located in Lavender Beds and Mist.
