First Floor - Construction
The first floor isn't always going to be the lowest level of every building. Sometimes the first floor will be referred to as the floor at ground level. Most of the time, the first floor is going to be located at the same level as the main entrance to the house. However, sometimes you will enter a home, onto the middle of a stairway landing. If this is the case, usually the lower level of the home would be the first floor.
If you're building a single story home, there's a good
chance that you're not going to be installing a stairway, unless you
have a set of stairs going to the attic. This isn't uncommon, especially
in older homes with large attic areas.
If you're building a two-story home, there's a good chance that you will
need at least one set of stairs, going up to the upper level or second
floor of the house.
Don't get confused, if the house is built on the side of a mountain, you
could enter the second level of the home, in the front yard, at ground
level. Until you go down a flight of stairs and reach the first floor at
the backyard, ground level again.
If you're building a new house, each floor level should be marked
correctly, in order to eliminate any confusion.
