Spotted in a Bourne back street, I suspect something bad is about to happen to this rather attractive bungalow. I'd date it as later 1930s to 1950s, and pretty much unchanged since then. The door and window look about right, even down to the colours. If that Disco wasn't in the way, the garage looks pretty typical of the period too.
My guess, and hope, is modernisation. The house opposite was also a bit of a time capsule, but has been sympathetically brought up to date. I know you can't live in a museum, but it's still nice to see unmolested buildings.
