The L-shaped stair has a 90-degree turn at the landing. Depending on the space you’re working with, this shape could use long or short legs, and occupies about the same amount of space as a curved staircase. A variation of this type is the L-Shape with winders which when short on space takes the typical landing area and adds angled treads to ascend in a shorter run. (Make sure these winders comply with local building codes).
