Interior angle formed by two walls meeting (4)

I believe the answer is:

nook

(Other definitions for nook that I've seen before include "Corner - narrow recess" , "shady retreat" , "Sheltered corner" , "Recess offering seclusion" , "Corner or small recess" .)

I've seen this clue in The Guardian.
