5 Types of Stairs | Types of Staircase | Types of Stairs Design
Stairs are an essential component of any structure having multiple floors. In fact, staircases and stairs have been around nearly as long as humans.
There are various types of stairs used in the home. The major function of stairs in the building is to provide ease of moving from one level to the next without much thought.
6 Types of Staircase Design
The following are different types of stairs options available for home,
1. Straight Flight Stairs
Straight flight stairs
These are continuous stairs along which there is no change in direction on any flight between two successive floors.
The stair may consist of either one single flight or more than one flight (usually two) with a landing. These types of stairs sometimes have only 1 flight of stairs.
These stairs are used for houses where there are restrictions in available width for its location, but enough length is available. As there is no change in direction, risers facing the ascending person cause uneasiness and monotony.
Straight flight stairs with a landing may further increase the length of stairs and had very little advantage.

2. Quarter Turn Stairs
When the direction of the flight is changed at right angles either to the left or to the right, quarter-turn stairs are used. The change in direction can be affected by either introducing a quarter space landing or providing winders at the junction of two flights.
Half turn stairs: Half turn stair is the one that has its direction reversed or turned through 180° by introducing a half-space landing or winders. This type of stairs is commonly used in residential buildings and public buildings.
These may be of two types:
a) Dog-legged stairs b) Open newel stairs or Open well stairs.

3. Dog-Legged Stairs
This name is given because of its appearance in sectional elevation. A dog-legged stair is called from its being bent or crooked suddenly round in fancied resemblance to a dog’s hind leg.
The dog-legged stairs consist of two flights of steps that run in opposite directions. No space is provided between the flights in the plan.
Usually, a half-space landing is placed across the two flights at the change of direction. This type to accommodate two widths of flights of the stair is useful where the width of the stair hall is just sufficient

4. Open Newel Stairs or Open Well Staircases
The open newel staircase is very similar to a doglegged stair. There is a well opening between the flights and it may be used to accommodate a lift.
The width of the stair would therefore be twice the width of the stair plus the width of the good hole or opening (1500 mm to 10,000 mm). Open newel stairs require more space than a dog-legged stair.
Open Well Staircase
At the head and foot of each flight of the stair, newel posts are placed which form a conspicuous architectural feature for the stair to be called newel stair.
5. 3 Quarter Turn Staircase
3 quarter-turn staircase type of stairs change their directions 3 times i.e., through 270° with its upper flight crossing the bottom one, In general, in this type of construction, a bigger open well is formed.
6. Circular Stairs
In these stairs, all the steps radiate from a central point of a semi-circle (in plan) in the form of winders. The circular stair is commonly provided at the entrance of a building for a better architectural appearance. These are commonly constructed in R.C.C. and brick.
7. Spiral Stairs
Spiral Stairs
These stairs consist of same-sized winders provided at a constant deflecting angle to offer a continuous change in direction along within elevation. They radiate around a central newel post and occupy the least space.
The overall diameter of such stairs (winders) may range from 1 m to 2.5 m. The stairs are not comfortable as they are full of winders and continuously change the direction.
When the available space is too small and the number of users is limited, this type of stair is constructed with cast iron or R.C.C.

8. Bifurcated Stairs
This type of stair is very common in modern aristocratic symmetric public buildings at their entrance which appears as a prominent feature.
The stair has a wide flight at the bottom, which bifurcates into two narrower flights, one turning to the left and the other to the right at the landing.
It is a combination of two quarter-turn stairs symmetrically arranged.
The most common type of stair which is provided in residential houses is the dog-legged type. Open well type and bifurcated type stairs are provided n public buildings.
Geometrical type stair is provided to give a better appearance, straight flight type stirs are most commonly used in residential buildings.
Three-quarter turn stairs are adopted in special cases as in posh hotels with a very wide staircase room incorporating reception in between. It may also be provided in palaces with more headroom to create a spacious and majestic look.
Spiral stairs are provided when space is not available for the common stairs type. It is provided at the back of the buildings for sweepers or servants for cleaning the bathroom, w. c., etc.
Features of Stairs
A continuous series of steps form a flight and there may be two or more flights between platforms called landings.
The horizontal upper portion of a step is called a Tread and the vertical or front portion of a step is called a Riser.
Proper sizes of treads, risers, newel posts, handrails, and balusters are designed for stairs to provide comfort and safety to the persons using them for easy and quick access to the various floors.
Flights of stairs and landings encased on either side by balustrade are called a staircase. The opening or space occupied by the stair is known as a stairway.
The means of communication between the various floors can be also provided by lifts, ramps, ladders, and escalators.
The materials used in the construction of stairs are stone, steel, wood, R.C, and cast iron.
Fire protection of the staircase is extremely important, particularly in multi-storeyed buildings. Staircases not only provide access and communication but also are a path for the spreading of fire from one floor to another.
Also, people on higher floors rush down the stairs during a fire hazard. Lifts are easily paralyzed then. Staircases therefore must be enclosed by fire-resistant walls, floors, ceilings, and doors. It is desirable that the linings to the walls and ceiling are non-combustible.
