The Qualities of a Good Staircase

 

Good Staircase

A good staircase is an essential part of a building–be it for a residence, community, or business. It is a series of steps arranged in a fashion that allows people to go from one floor to another with ease. It must be built in such a way that avoids inconvenience and accidents for users. 

Even if there are elevators in the building, stairs must be present for exiting during calamities or emergencies.

Stairs also make it possible to create multiple story buildings that save horizontal space. This is particularly the case for commercial building stairs — vertically expanding a business is more cost-efficient than expanding it horizontally. But a staircase's functionality is only as good as its design.

Some Staircase Design Principles

Staircases may be circular, straight, spiral, or flared, but generally, a good staircase must follow certain principles to ensure optimal convenience and safety. 

Firstly, the location of the staircase is preferably central. This is to provide sufficient light and ventilation, and easy access for everyone in the building.

A flight of stairs is usually limited to 12 steps and has a minimum of three. To avoid accidents, open-well stairs must have balustrades, and wide stairs must have hand rails on both sides. 

The materials used to make the stairs should also be sufficiently strong to resist impact. Ideally, the material should also be fire-resisting.

The distance from a step to the flight directly above it must not be less than 2.3 metres. This is to ensure that a tall person may use the staircase with some headroom. 

The width of the stairs is also important. For public buildings, it must be at least 1.8 metres and at least 0.9 for residential buildings. The landing's width should also not be less than the width of the stair. The inclination of a staircase should be about 30 to 45 degrees. 

 

Take these principles into account when designing the stairs for your building project.
