All stairs are built on the same concept of a set of steps that lead from one floor of a building to another but not all stairs are the same. There are different types and designs for each set of stairs with each providing different benefits and disadvantages. When constructing a staircase there are factors that should always be put into consideration.

Below are some of the types of staircases and differences in each of them.

Straight Stairs


Straight staircases are the most common type of stairs they are found almost everywhere.

Some of the distinctive perks of straight stairs include:

  • All steps go in one direction
  • Simplest form of stair arrangement
  • Less complex railings and handrails
  • They work well even with minimal space
  • Change of direction can be easily done
  • Landings are not required in most designs
  • The staircase does not need intermediate support
  • Building rails for this straight staircase is easy compared to the rest.

Disadvantages of straight stairs

  • Lack of privacy between floors unlike the l-shaped staircase which creates privacy.
  • Most common type of stairs so they won’t stand out as much

L-Shaped Stairs

This is a combination of two or more straight staircases with a landing. They are also basically a straight staircase with a turn.


Some of the distinctive advantages of L-shaped stairs include

  • They are attractive and take up less space
  • Can be used in a corner of a room and they are also easy to navigate because of the landing width
  • The landing provides a rest area
  • Design is sometimes safer than the straight staircase because the landing provides a base that reduces the chances of a fall
  • The l-shape acts as a sound breaker

The l-shaped staircase also has some disadvantages

  • Complex to build
  • Costly to construct
  • Require a landing for the turn to be in place
  • Handrails for these staircases need expertise in construction.

U-Shaped Stairs

This is a combination of two flights of stairs going different directions with a rest landing of 90 degrees. Some of the distinctive perks of U-shaped stairs include:


  • Seem more interesting than the straight stairs
  • The landing offers a resting base
  • Uses less floor space
  • Ideal for a corner design.

Disadvantages of u-shaped stairs

  • The shape makes it difficult when moving large furniture because of the turn
  • Difficult to construct.

Spiral Stairs

These type of stairs are mostly confused with curved stairs because of the design. It is considered a novelty by most people. They are mostly found in beach houses because of their contact nature


Advantages of Spiral Staircase

  • These staircases have one central post where all the steps are attached
  • Take up less space
  • More attractive in appearance since they create some sense of style
  • Don’t require extra support structure making installation easier.

Disadvantages of spiral stairs

  • Only one person at a time can use the stairs and requires care because the inner of the step is narrow
  • Unlike straight staircases they are difficult to maneuver especially when moving large items up and down the stairway
  • Difficult to plan.
