Stair Designs

Winder Stairs have pie shaped steps, not very safe (ankel breaker), and is used when there is not enough space available for "L" Stairs.
"U" Stairs have one landing, flights are parallel and have a 180 degrees turn.
Double "L" Stairs have two landings, so two turns, used when no space is available for Straight Run Stairs or "L" Stairs, also more expensive and breaks up floor plan.
Straight Run Stairs are the most commom stairs, no turns, less expensive because uses less material, and requires a long open space.
"L" Stairs have one landing, one turn at 90 degrees, and is used when space is not available for Straight Run Stairs.
Circular Stairs have a irregular curve or arc, trapiziodal shaped steps,, and most expensive to built because has to be custom built.
Spiral Stairs are used when little space is available, it is gaining in popularity, but not very safe; usually has wider steps, because always turning.
