How Do You Draw a Spiral Staircase in Plan
Spiral Staircases Design
Custom Spiral Staircases are a unique design feature in whatsoever business firm or commercial space. They are oftentimes fitted in houses where the space available is an event and a conventional staircase would non exist possible. With special shapes and designs, they oftentimes become a featured interior design object in many projects.
With our expertise even an ordinary tiny spiral staircase tin become a Screw Staircase Yard Blueprint.
The well-nigh popular choice is the screw staircase architecture with round base of operations, but the square base screw staircase is a good option too if you want to have a comfortable staircase with a modern design.
In terms of design, there are a number of technical issues yous need to take into account when designing a spiral staircase. In that location are indeed some geometrical rules you need to follow and take into account to design a spiral staircase in the correct mode and with the right dimensions.
Also with this screw staircase pattern guide you will learn how to design (and build) a perfect spiral staircase step by step. Let's start!
- Stride one. Ceiling opening measures. Spiral Staircase Opening.
- Step ii. Number of steps per 360 degrees.
- Step 3. Floor to Flooring measure out. Footstep 4. Determine the location of the top landing platform.
- Stride five. Draw the spiral staircase.
- Footstep half-dozen. Depict the landing balustrade.
- Footstep seven. Check the head clearance (head room).
- Stride 8. Bank check Building Regulations.
The number of steps is in fact limited by the flooring to floor superlative (staircase summit) just too past the geometry of the round shape itself. In this article nosotros are explaining how the round screw staircases work. Square staircases are in fact a piffling bit different, we will deal with this in other article.
Here beneath you find some useful indications to determine how many steps you lot need on your spiral staircase plan. The number of steps per turn (360 degrees circle) depends on the spiral staircase diameter you lot need.
Step 1. Ceiling Opening Measures
Firstly bank check the measures of the ceiling opening (stairwell opening) you take.
If the arrival floor of the staircase is a mezzanine and not a spiral staircase opening, you do not demand to check this.
Remember that the spiral staircase diameter will have to be 100 mm smaller than the ceiling opening. This is to be able to fit the staircase in an piece of cake fashion and to allow for the paw to catch the handrail without touching the slab.
If your stairwell square opening is for example 1600 ten 1600 mm (or round bore 1600 mm) the diameter of your staircase will be 1500 x 1500 mm (or 1500 mm diameter).
Footstep two. Number of steps per 360 degrees.
At present that you know the spiral staircase diameter, you lot have to detect out how many steps you need per plow of 360 degrees (the total degrees of a circumvolve).
This chart will help yous.
On a spiral staircase cartoon with a diameter of 1500 mm this chart is saying that we can accept 12 or 13 steps per circle. We will go for 12 as this will give the states a wider center going (stride of 30 degrees).
Step iii. How to blueprint a Spiral Staircase. Floor to Flooring measure out.
Secondly, check the flooring to floor measure and Spiral Staircase floor plan.
Nosotros have every bit example the floor to floor height of 2700 mm. For instance, this value has to exist divided for the advised ascent value which is between 220 and 240 mm.
We can therefore have 12 risers of 225 mm each. The number of steps will be then 11 + ane landing platform.
The value of risers and going have to be checked co-ordinate to the edifice regulations of your area. In addition, we give you lot here beneath a reference table listing UK Building regulations.
The landing platform can be round, trapezoidal or square. We normally recommend avoiding square platforms as they may reduce the caput clearance (see Step 6).
Step 4: Determine the location of the tiptop landing platform.
Depending on the space you have at staircase get out, you certainly at present need to observe out the best position where to put the landing platform (staircase exit).
On a custom screw staircase you tin can have the elevation landing in unlike shapes or larger to permit for a conformable staircase exit. Check this spiral staircase drawings as instance.
Step 5: Draw the screw staircase plan – Screw Staircase Blueprint Calculation
Draw a crude sketch to see where the entry step will be. If y'all exercise it manually, y'all need to showtime from landing platform coming downwardly. Otherwise, a simple fashion is to utilise a stair calculator you discover on the web.
Here beneath an example of a popular Screw Staircase Design.
Staircase: diameter 1500 mm, floor to floor acme 2700 mm, 12 risers of 225 mm, eleven steps +i landing platform
Hither is how the staircase will look:
Spiral Staircase Outdoor
The chief rules to draw an exterior spiral staircase are similar. The external screw staircase normally serve to reach a balcony, terrace or to enter a door at first floor. There are no major obstructions or walls, therefore you may be able to design a spiral staircase plan with a broad diameter.
Being the external spiral staircase exposed to weather atmospheric condition which may be severe in some areas you certainly need to pay attending that all the screw staircase parts are properly treated and suitable for their apply. The steel must be in fact hot galvanized, the stainless steel AISI316, the wood parts suitable for external use. For outdoor we also recommend a woods spiral staircase made of teak, iroko or whatever other difficult wood non sensitive to humidity, cold and hot temperatures.
Step 6: Describe the landing balustrade
Depending on the position of the landing and of the wall you lot have at first floor you demand to check how much landing balustrade or guard-runway you need to protect your ceiling opening. If your spiral staircase opening is round then yous need a round landing balcony. If it is square you lot will need a directly landing balustrade design.
Footstep 7: Check the head clearance (headroom).
The clear height nether the landing platform is chosen headroom and information technology is important to take minimum of 2000 mm, to avoid your caput bumping on the landing platform edge. For instance If yous use a staircase calculator it will calculate this measure for yous. A minimum of 2000 mm is also required past building regulations.
Step 8: Check Building Regulations on how to design a Spiral Staircase.
At last, bank check that all measures are complying to the staircases edifice regulations in your area and you are done! Good Job!
For England and Scotland you can download the complete Spiral Staircase Building Code on the uk planning portal website.

As for the materials used in the manufacturing, the selection is huge. For example if you like the classic manner you lot tin choose amid different types of woods as oak, beech, walnut and others. On the other paw of you prefer the modern staircase look, you tin can go for a combination of glass and painted steel or stainless steel staircase.
In conclusion, Screw Staircase Prices will vary depending on the material yous cull, a metal staircase will be the virtually toll-effective, whereas the drinking glass spiral staircase will be the most expensive. For case, this is due non only to the cost of glass itself, only also to the engineering involved in manufacturing curved drinking glass panels for railings.
