My best guess at this stage would be a country rectory, or possibly a schoolmaster's house. A bit big for a village school, though, and no sign of it being attached to the school (which was common), but I could imagine it as a standalone master's house at a public school.
It looks to have been built all of a piece, and the creepers and mature trees suggest it's been there a while. The stone looks clean, so probably not in an industrial area.
