A strange place for a bust

I was in Berkhamsted at the chiropractor's again today and spotted this on my post-treatment walk. The building (this is a side of it) is at the far end of the High Street and houses a veterinary surgery. Not the sort of place you'd expect to find this terracotta bust. The more I look, the more the set-up puzzles me. The windows have been added at a later date, the roof seems to have been changed and the bust's niche looks like a bricked up window. Intriguing.

Curious, it looks like the building as seen a few changes. That bust does look a little out of place there.

That is, but it makes for a very interesting facade. :D

it seems the original window is right in the chimney !? That is odd but yeah the bust is a little out of place there.
