What Is a Straight Staircase?
A straight staircase is a type of staircase that extends in a straight line from the lower floor to the upper floor without any change in direction.
These staircases are commonly installed along walls and are frequently found in Japanese houses. Unlike L-shaped or U-shaped staircases, a straight staircase offers a simple and direct ascent. However, it’s important to note that there is a risk of falling all the way down to the bottom in case of a stumble, especially at the top.
These dimensions serve as minimum requirements, but they are often adjusted for enhanced usability. Many homeowners refer to the Housing Performance Indication Standards, which provide criteria for gradients, risers, and dimensions of curved parts. These standards take into consideration the needs of the elderly and establish different levels of specifications to ensure safety and accessibility.
