Where do you live? That will makes a difference as to what people
suggest.
One possibility is Camellia - it will grow taller than you mention but it
can be kept trimmed.


Thanks everyone. I live in West Yorkshire (UK). The shrubs around the gap
are mostly the aforementioned hebees, but there's what was no doubt one
year's family Christmas tree (now about twelve feet tall) quite close too,
and a nice rosemary bush that's doing well. Also a holly.

Camellia seems to be the consensus so far!!
