I am a school librarian in the U.K. who read everything I could find when I was a kid in the 70s and 80s. I have never been able to track these down.
1. A novel I read around age 10 which I borrowed from a family up the road in 1980ish. All I can remember is the main character was female and for some reason she goes to live on her own in a small cottage in or on the edge of a forest, possibly a meadow, there is a dad at some point.
2. I am sure this one is from slightly earlier and is set in a busy American city, possibly New York. It might have been a picture book and my memory is that the main character lives with many other children (siblings) in some kind of an apartment in which they have many floor to ceiling bunk-beds, possibly several beds high which are kind of built into the walls.
First one might be ‘Mandy’ by Julie Andrews Edwards.

Came to the comments to suggest that! One of my favorites when I was young.
