ADVANTAGES OF A STRAIGHT STAIRCASE:

Though there are so many new varieties and styles of staircases available today, the straight staircase continues to be popular because of the following advantages.

Affordability A straight staircase is cheaper than other types of staircases such as U-shaped or curved. This is because the construction process is much simpler and less time consuming.

Simplicity Some people prefer the simplicity of a straight staircase. When planned properly and built using attractive materials, a straight staircase can be simple but quite elegant.

CONTINUE:

Safety Because a straight staircase offers a clear view of the stairs, there is a lower chance of falls or misplaced steps. In contrast, curved staircases often require a lot of attention when you are going up or down one.

Ease of Construction A straight staircase is easy to plan for and construct. You can have one ready for use in much less time than it would take to construct a curved or platform staircase.

DISADVANTAGES OF A STRAIGHT STAIRCASE

Straight staircases also include a fair share of drawbacks. Some of these include a lack of privacy between two levels and the possibility of serious injuries.
