This is probably the second most popular stairway used by architects and
designers, next to Straight stairs. These stairs can be used more
efficiently under certain circumstances than other types of stairways.
They are usually relatively inexpensive to build and usually provide people with an excellent safety use level. This is only my personal opinion, but it seems to make a lot of sense.
If some one fell down a Straight set of stairs, they could end up falling all the way down the stairway, but with a U-shaped or L-shaped stairway, there's a good chance they would only fall half the distance. This could reduce the amount of injury they might suffer and that's why I'm providing the stairway with an excellent level of safety.
The biggest problem inexperienced stair builders will face with this type of stairway is positioning the stair stringers. I can't tell you how many times I've seen these stairways sticking into a hallway or even the platform area, when they shouldn't be.
