I am looking for one word (ideally, a noun) to describe 'not enough space in a building', 'a lack of space'. Could I use 'narrowness' or is there a better word?
According to the Oxford Dictionary, 'narrowness' means:
the fact of measuring a short distance from one side to the other, especially in relation to length (one of the meanings)
Is 'narrowness' only about the relation to length or could it be used in general about the space being too small?
