How much does a spiral staircase cost?
A spiral staircase ranges from $1,000 to $20,000. Installing one averages around $10,400. The total depends on the material type plus the height and width of the stairs. The installer’s labor rate impacts into the price, too.
Can I build my own spiral staircase?
You can build your own spiral staircase with a little bit of welding skill and about $400.00 worth of steel, even at current higher steel prices. I have built 18 spiral stairways in the last 15 years, all with some wooden components (treads and handrails).
What size opening do I need for a spiral staircase?
3’6” translates to 42 total inches in diameter and therefore the MINIMUM opening size that you need MUST be 44 inches x 44 inches (44”x44”). You need at least 44”x44” opening because you’ll need two extra inches for your fingers to travel along the handrail as you walk up and down the stairs.
Do spiral staircases meet building regulations?
All building regulation spiral staircases should comply with the 100mm sphere rule, i.e there must be no gaps greater than 99mm anywhere on the spiral staircase. However, your building control surveyor may still allow these types and designs of balustrade if you ask.
How wide is a spiral staircase?
Spiral staircases generally range in size from 42″ to 76″ in diameter. The floor opening at the top of the staircase must be two-square-inches bigger than the staircase’s diameter. Spiral staircases are also measured by their floor to floor height, footprint, walking space, and landing length.
What is the smallest spiral staircase?
Because your stair’s diameter is the total width of your stair, it will also determine the footprint. The smallest spiral stair diameter that we offer is 3’6”, which translates to a 42” x 42” footprint.
Does a spiral staircase save space?
The main reason spiral stairs were invented was to save floor space. Spiral Staircases do take up less space than conventional staircases. This is because the steps are all located within the diameter of the spiral, regardless of the height.
How many square feet is needed for a spiral staircase?
A spiral staircase will save you space, with a typical 44” by 44” footprint that allows for the stairs themselves, the railing, and additional space for a hand holding the railing. By comparison, a traditional staircase requires an 88” by 36” footprint on the bottom level and a 48” x 36” footprint on the top level.
How do you calculate stairs for a spiral staircase?
The calculation of dimensions of a spiral staircase is very critical and performed with utmost care.Steps to Design a Spiral Staircase Floor height ‘h’ = 2700mm. Riser ‘r’ = 225. No of risers =2700/225 = 12. No: of Steps = 11 + 1 landing platform.
How high can a spiral staircase be?
Most straight stairs have a typical riser height between 7” – 7.5” whereas spiral stair riser height has a maximum riser height of 9.5”.
Do spiral stairs need a landing?
Landings, where required, are attached to the top of the staircase and provide the path to the upper level. Landing are required when a staircase is installed through a hole in the floor. Landings are not required if the staircase is attached to the corner of a balcony face application.

How do you secure a spiral staircase?
Or, cut a piece of colorful adhesive and stick it to the nose of each step so it catches the eye more easily. The edge of each horizontal step is also called the “nose.” The risk of taking a misstep is even higher on a spiral staircase, and illuminating each one makes your trips up and down a bit safer.
How many feet do you need for a staircase?
A standard staircase occupies 30-square-feet of space above and below the staircase. This is the most common dimension, given an 8-foot ceiling, where the staircase width measures 3-feet (36-inches) and horizontal floor space occupied measures between 9- to 10-feet.
Do you need planning permission for external spiral staircase?
The external spiral staircase is a modest structure located in the corner between the rear wall of the building and the rear extension. I consider that it has no material affect on the external appearance of the building and it is therefore not development that requires planning permission under the 1990 Act.
