Adding a Spiral Staircase

Spiral Stairs, Stairs May 7, 2019 Sonia



From kit-built to custom-made, adding a spiral staircase is easier than ever.

Spiral stairs boast the unmistakable design of having treads wind around a central pole, and typically have a handrail on the outer side only. This design is usually employed because a tight spiral stair with a central pole is a highly efficient use of floor space. Although planning and constructing a  spiral staircase traditionally has been a difficult feat, developments in manufacturing have led to the introduction of modular spiral stairs. Steps and handrails can be bolted together on-site to form a complete unit, and the stairs can be made from steel, timber concrete or a combination of materials.

Although a spiral staircase can’t be used as the main access to your home (per building code requirements), it can be a convenient way to get from one level to another and will occupy half the space. Are you planning an addition and need a convenient way to access the new area? Have you built a deck and need quick access to another level? This article explores some of the modern spiral staircase options available to homeowners in need of such a solution. Note that building codes impose restrictions on the use of spiral stairs, so check with your local inspector for guidelines.

Spiral Stairs in a Kit

Spiral and modular staircase kits from Arké can be built in a day by the average DIY home enthusiast. Arké is the U.S.-based subsidiary of Italian spiral stair company Fontanot. Arké spiral stair kits come in a variety of setups and materials, such as wood, metal and steel. The kits require no special tools or skills for assembly. The all-in-one kits include treads, landing, balusters, handrails, hardware and accessories. There is nothing to paint, weld, stain or seal, and the kits are in stock for immediate delivery.

A tight spiral stair with a central pole is a highly efficient use of floor space.

The homeowner designs the Arké spiral stair online with a simple step-by-step website tool at Arkéstairs.com. Once you’ve determined your staircase style, your exact height measurement, the directional turn of the spiral, and the size/type of your landing, Arké assembles a kit to fit your needs and ships it to arrive within seven working days, ready for installation even by a do-it- yourselfer.

The all-in-one kits from Arke include treads, landing balusters, handrails hardware and accessories.

When ordering a staircase kit, the first step is to decide whether or not it’s an indoor or outdoor installation. Step Two is to measure from the finished floor on the top level to the finished floor on the bottom level of the proposed stair location. This determines the exact height required for the installation.

Next, measure your total amount of available space to determine the correct diameter of the stair. The finished space should be at least two inches larger than the total staircase diameter. (Note: If the installation must meet the IRC Building Code, the homeowner will need to choose the largest of Arké’s three sizes—63-in. diameter—which is designed to meet the code requirement.)

With the Arke spiral staircase kit, height is adjustable with the use of a patented space system.

The Arké staircase kits are  available in three different colors with your choice of wood or metal treads. Each model contains all  the necessary components and detailed assembly instructions as well as a DVD.

Arke premier interior kits offer a patented universal landing as a standard feature, which provides greater flexibility and easier installation.

When it comes time for installation, the Arké kits offer three unique design features that address  common problems.  First, the system’s height is adjustable with the use of a patented spacer system. Rather than rely on an exact height measurement, the standard  spiral kit is adjustable in height from approximately 8 ft.-3in. to  10 feet. (For heights above 10  feet, additional risers and center pole extensions are available.)

Assembly of the Arke kit begins with installation of the base-plate and the center pole.

The treads and spacers slide over the pole.

Another key Arké feature is the option for directional turn of the spiral. Most manufacturers produce a specific unit based on  the rotational turn (clockwise or counterclockwise) of the spiral for specific installation. This requires careful planning and measurement to avoid a restricted or blocked floor exit. The standard Arké kits are designed to make a complete 360-degree turn. Therefore, the first step will be directly underneath the landing. However, by adding or subtracting risers the rotation will change by approx. 30 degrees per riser. Furthermore, Arké spiral stairs can be turned in either clockwise or counterclockwise, which greatly minimizes the chance of error in the order and installation.

Add the second section to extend the height.

The staircase shown has a mezzanine landing.

Finally, Arké offers options in landing size and type. For the landing at the top of the stairs, most manufacturers produce a specific design for the planned installation, either a mezzanine, round or square landing area. Arké’s premiere interior kits offer a patented universal landing as a standard feature, which provides greater flexibility and easier installation. Learn more at www.arkestairs.com.
