First surface, not first floor.
We're the stupid ones on that score. Ground floor is idiotic, it's the 1st floor of the building.
I hate basement level numbering that is B1, B2, B3, B4 etc. -1, -2, -3 is clearly the better option.
The zero still exists whether you count it or not, just the cashier would look a bit daft handing over zero mars bars (why is zero plural?).
It would be equally daft if you went from floor 1 to floor -1 hence the existence of floor zero, aka the ground floor.
so if the ground floor is the first floor then surely the basement has to be the ground floor because its in the ground and the first floor is first so then the basement is the sub basement but how can you have a sub basement without a normal basement first?
lower ground floor
how many sub basement do you need before you get to the underground lair?
What number comes between 1 and -1?
What if you have a huge, underground, villainous complex. I really don't have the room for sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-basement on the lift control panel.
What if the building is a helix?

You're thinking it wrong:
Walk in to a shop and see a stack of 3 mars bars. Ask for all the mars bars. How many do you get?
3, of course.
Why not 4?
Because the ground isn't a mars bar.
Someone has already mentioned it but its comparable to a staircase / ladder. When you step onto a ladder / staircase, you are elevated by one rise, you are therefore on the first rung/step. You wouldn't say you were on the first rung of a ladder whilst you were stood next to it.
Someone has beaten me to it here, you can see on this detailed plan exactly what the floors should be known as.
Show me your design that shows that they are wrong.
It's funny how if you are sky diving, you hit the ground, not the first floor.
If you jump off a building, you hit the ground, not the first floor .
If you jump off outside the window from the first floor, you hit the ground.
If you jump off a floor inside the building, you hit the first floor?
WHAT ON EARTH? What kind of logic is that? You are on the first floor just because you step inside a door?
HSBC in Hong Kong has no door as such on the ground floor, the entire ground floor is wide open. Just because you are inside the footprint of the building means you are now on the 1st floor? What if I am 1 foot in it? Am I both on the ground and 1st floor?
What do you call a building with no floors?
does nothing exist?
Everyone agrees that the floor at street level is a floor. It's a surface laid on the foundations. It's a floor.
Now many people call it a ground floor because it's at ground level. However, since it's a floor it's the FIRST floor of the building.
If you live in a bungalow and fall out of bed.....where do you land? THE FLOOR
Would it be identical, or would their be better than yours and you don't want to get shown up?
