These stairs have no new posts and are geometric in shape. The change of direction in these stairs is achieved by wind. Stairs require more skill to build and are weaker than open new stairs. These stairs have an open well curved between the front and back flights.

These stairs, when viewed from above, appear to follow a curve with two or more centers of curvature, like an ellipse.

These stairs are similar to circular stairs except that the radius of curvature is smaller and the stairs can be supported by a center post. The overall diameter of such stairs can range from 1 to 2.5 meters.

These stairs, when viewed from above, appear to follow a circle with a center of curvature and a large radius. These stairs are generally provided at the rear of the building to provide service access to different floors. All steps originate from a new post in the form of a wonder. These stairs can be…

This type of staircase changes its direction by 270°. In other words, the direction is reversed three times and its upper flats cross the lower ones. An open well is formed in this type of construction.

These stairs change their direction by 180°. It can be either ‘dog-legged’ or ‘open navel type’. In the case of dog-legged stairs, the flights are in opposite directions and no space is provided between the flights in the plan. Open staircases, on the other hand, have a well or opening between flights and can be…

They are provided when the direction of flight has to be changed by 90°. The change in direction can be effected either by introducing a landing at a quarter space or by providing a winder at the junctions.

These are stairs with no change of direction in any flight between two consecutive floors. Straight stairs can be: Run straight between destinations with a single flight.Run straight with a series of flights without changing direction.Parallel stairsAngle stairsScissor stairsStraight stairs may change direction at the middle landing. In the case of parallel stairs, the stairs…

It should have adequate lighting and adequate ventilationIt should have stairs of sufficient width to allow adequate access by persons due to excessive time or conditions. In general, the clear width for internal stairs should be at least 50 cm in one and two-family houses, 90 cm in hotels, motels, energy buildings and industrial buildings…
