14. 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.

15. 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.

 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.
