How to Design Spiral Staircases Step by Step

The spiral staircase used to follow a helical architecture, in which the treads of the spiral staircase radiate around the central pole. The spiral staircases have often been found in industrial contexts. The reduced tread width of the spiral staircases allows for a very compact design of the staircase. For this reason, this type of staircase can be very steep.

There is a handrail on the outer side of the spiral staircase, and on the inner side of the spiral staircase, there is a central pole. The central pole of the spiral staircase helps to provide structural support to the entire staircase structure. Due to the presence of a central pole in the spiral staircase, there is no need for additional support structures. This feature helps to make the installation procedure of the spiral staircase easier, rather than the other types of staircases.

Discuss different types of Spiral Staircases

The spiral staircases are available in different types, which are as follows:

Spiral Concrete Staircases

The spiral staircases have been made with concrete, which helps to provide an ultra-modern appearance. The natural concrete used in this type of staircase is very cold. In this context, the mixture of natural concrete along with marble dust helps to create a warm impression, and it can also be adjusted to all types of floors and houses.

Spiral Glass Staircases

The central column of the spiral staircase can also be finished with the glass treads. In this case, the glass treads are either round at the side or angular in shape, which can be adjusted according to the wall shape of the building structure. Generally, the railing of the spiral glass staircase is made with curved glass and hung from the ceiling of the building structure.

Spiral Wood Staircases

The sky-screw of the spiral staircase can also be made with wood. The spiral wood staircase has the nativeness, which can not be reached by any other material. The spiral wood staircase helps to create innovative and new designs in modern architecture.

Learn about Spiral Staircase Dimensions

• The spiral staircase has been designed with specific dimensions. While considering the size of the spiral staircases, it needs to be ensured that the size of the spiral staircase fits the building’s space. This should be done in a way to make the best use of the building’s space, thus reducing the space wastage possibilities and also does not limit the desired functionalities of the building’s space.
• The height of the spiral staircase is another important dimension, which should be measured from floor to floor height. In this context, while installing the spiral staircase on a deck, the floor-to-floor measurement should be done from the length between the ground level and the finished deck flooring. The installation of the spiral staircase has been done in two ways, for example, the spiral stairs have been installed coming off a loft, deck or through a hole in the building’s floor.
• The diameter of the spiral staircase is another important factor that needs to be kept in mind while planning to install the spiral staircase. The wall of the building's structure may limit the diameter of the spiral staircase. The diameter of the spiral staircase refers to the width of the stair or the space that is taken up by the staircase. The builder can use the duct tape to mark the space for the stairs on the floor.
• Due to the space-saving feature of the spiral staircase, users think that it is too narrow for regular use. In this context, the user has to measure the walking path to achieve comfortable walking up and down the staircase.
• The platform size of the spiral staircase is another key dimension of the staircase. The platform size of the spiral staircase refers to the entry and exit point for the staircase. The size of the platform has been determined with the help of the spiral staircase diameter.

Learn about the Spiral Staircase Plan

To design a spiral staircase, proper planning is necessary. In this context, several steps have to be followed by the makers to complete the design of the spiral staircase.

• At first, the ceiling openings should be measured by the builders. In this context, it needs to be ensured that the diameter of the spiral staircase is 100 mm less than the ceiling opening of the building.
• In the next step, the number of steps of the staircase should be measured as per a turn of 360 degrees.
• After calculating the steps of the staircases, the builder also has to check the floor-to-floor measures as well as the floor plan for the spiral staircase.
• In the next step, the location of the top landing platform needs to be determined, which helps to allow for a comfortable exit from the staircase.
• The builders have to draw a rough sketch of the spiral staircase to see where the entry step of the staircase will be.
• In the next step, the builders have to check how the landing balustrade or guard-rail of the spiral staircase is required to protect the ceiling opening.

• The height under the landing platform, called headroom, should be a minimum of 2000 mm, which helps to avoid head bumping on the edge of the landing platform.
• At the final step, the builders have to ensure that all measures comply with the regulations of the building’s staircase.
