The Adobe Stairs is an inclined ramp that can be used to overcome heights. An Adobe Stairs is 1 foundation wide, 1 foundation long and 1.5 walls tall, which sometimes makes planning structures difficult.
It's often easier to build a stairs from the top down, as the excess stairs will usually extend through the floor. Building it from the bottom up will cause it to protrude over the surface you're trying to connect it to.
