This style of home is quite popular in the UK. Many of the townhomes, or terraced buildings as they're known there, were built in the 19th and 20th centuries.
It was easier to make sure such homes had enough structural integrity, in part, by having smaller-than-expected doors.
Why do they open onto the pavement (or sidewalk, as Americans call it)? Well, these terraced houses were pretty humble abodes when built, with plot sizes to match. They weren't entirely without outdoor space either - with yards common in the rear.
UK users quickly flooded the comments to inform the confused American that these homes were quite typical for the UK - while hitting back with some good-natured mockery.

One person, @sjtrainsyt_alex22195, said not to worry - pointing out that the doors open inward, so no pedestrians are going to be toppled over by a sudden door opening.
Others joked that the homes in the UK were safer than most things Americans deem safe, like schools.

Some users have speculated the account is satire due to the "obvious" questions the user asks.
