How many front doors are in London?

It’s difficult to estimate the exact number of front doors in London, but we can try to make a rough calculation.

As of recent estimates, London has a population of around 9 million people. If we assume the average household size is around 2.5 people, that gives us approximately 3.6 million households. Since each household typically has at least one main entrance door, we would be looking at about 3.6 million front doors.

However, this doesn’t include extra doors (e.g., for backyards, garages, or multiple entrances in larger homes), so the true number could be higher.
