Floor numbering conventions

One of the things that is common in Europe is that building floors often start with zero for the ground floor and then go both up and down from there.

This is different than most of North America where the ground floor is usually floor number 1 (regardless of what it might be called) and then the floors go up from there.

Using the pictured example (above), the key difference is that, with the ground floor as zero, you end up with the above-grade floors being off by 1 and the top floor being 6 instead of 7.

There is a certain rationality to the European approach that I like, but I am curious how suites on ground floors get typically numbered. I will seek this out and report back.

At Junction House, our ground floor residences follow 101, 102, 103, etc. Following the exact same logic, the European equivalent would be 001, 002, 003, etc. This, admittedly, feels a bit odd.

Which floor convention do you find more intuitive?

Either way, I’m thinking about adopting the European approach for no other reason than that height is a sensitive topic in the world of development, so one less “headline” floor could be helpful. (Half-joking)
