This is Snuff Cottage in the historic village of Culross in Fife. It was actually the window that caught my attention. Around the top of the window it reads "Wha wad ha thoct it", which is Scots for "Who would have thought it", and the date 1673.
Now, I'm not tall (5'8" ish), but this door, like most of the cottages in Culross, is absolutely tiny. I would have had to duck to get through it for sure.
Incidentally, Culross is pronounced "Kooh-riss"
