Here is a photo of a more exciting example of a boundary going through a building, from Baarle-Nassau/Baarle-Hertog, a town which is in the Netherlands and Belgium. Some bits of Belgium are surrounded by Dutch territory and vice versa. This house has the border running through its front door.
There are similar examples on the Bangladesh-India border, some with enclaves inside enclaves, going down to individual buildings or smaller. All dating from which maharajah originally owned which land and whether they plumped for India or Pakistan back in 1947. The added excitement here is that Bangladeshis and Indians require visas to visit each other's countries. A visa can only be obtained by visiting the consulate and if the patch of India or Bangladesh you live in is only a few houses... It also plays havoc with services like water, electricity, hospitals...
The Bangladesh - India issue is almost no more. There's been a massive shuffle around and only one remains ...
