A special balustrade of stainless steel cables and steel balusters make the Kloe one of the most stylish spiral staircase kits around. It is made by an Italian company called Arke and is a re-design of their classic Klan spiral staircase – (the original model has been in production for well over a decade and is proven to be one of the most reliable spiral staircase kits on the market today). The Kloe spiral staircase is easy to assemble and most people manage to do this in a single day using standard tools for everything except cutting the cables – for which we sell special cutters if you need them.
The Kloe comes in different sizes and can be adjusted to suit most houses. For more information please read the height and layout tab. Otherwise the most common queries about the Kloe spiral staircase kit are:
What comes in the box?
A landing plate and brackets to fix it to the upper floor
A centre pole and base plate
Treads
Tread spacers
Balusters
Cables
Handrail
Two wall brackets
Written installation instructions and a DVD
What are the main parts made from?
The landing plate and treads are made from beech (a good quality hardwood). They come with a primer coat of either clear varnish or varnish mixed with a dark stain.
The balusters and tread spacers are made from steel tubes. They are powder coated and coloured either white, grey or black.
The handrail is made from polyurethane (a type of plastic) and has a wood effect finish to match the treads.
The cables are made from stainless steel.
How is the delivery made?
The Kloe spiral staircase is supplied in kit form. It is shipped in a large plywood box on a wooden pallet and depending on the number of treads ordered there may be a few smaller cardboard boxes as well. The delivery is made using a large vehicle with a tail lift and a pump truck because the main box is too heavy to be lifted by hand. The driver will take the goods off the lorry and deliver them to the roadside outside your property, or as close as possible if you live on an unmade road. From there you will need to provide the means of bringing them into the building. If you need to do this by hand you can do so only by opening the box and carrying in the pieces inside. It is not possible to move the complete box by hand as it will weigh at least 150kg.
How can I tell if it will fit my house?
You need to take a few measurements and then carefully read the information we give on heights and layout and fixings. If you have any questions please do not hesitate to call our technical sales team on 0800 098 8778. We're here to help!
Will my new staircase meet building regulations?
Approved Document K from the Building Regulations refers to British Standard 5395 1984 part 2 for guidance on the design of spiral staircases. Essentially the standard gives different requirements depending on where a spiral staircase is going to be used. For example the requirements for a staircase in a private house are different to those for a staircase in a public place. Even within a house the requirements can change because a staircase up to a small loft conversion can be smaller and steeper than a staircase going from ground to first floor in a family house. If your installation needs to comply with building regulations then you need to find out which category of spiral staircase is right for your situation (ask Building Control). Providing you buy the 1600mm diameter model, and you assemble it so that the rise per step is less than 220mm the Kloe will meet the requirements of a category A or "Small Private" stair. It is your responsibility to determine whether or not this will meet your requirements. Please note that the type of cable balustrade system used by the Kloe is not acceptable for use under the Building Regulations where children under the age of 5 are likely to have access to the stair.
Accessories for the Kloe spiral staircase
In addition to the Kloe spiral staircase kit there are some accessories available which you might need to finish your job. They are:
Riser bars for the Kloe spiral staircase kit by Arkè
Riser bars are horizontal steel tubes which fit between the treads for the safety of small children. You should fit them if children under the age of five are likely to have access to the staircase.

Landing balustrade kit for the Kloe spiral staircase kit by Arkè
The Kloe spiral staircase kit comes with enough handrail and balusters to go on the staircase and landing plate only. It does not come with any balustrade to sit on the upper floor. The collective name for the handrails, spindles etc that sit on top of the upper floor is landing balustrade. If you need landing balustrade you must buy it separately. It is sold in kits 1200mm long.

Staircase Height
At the bottom of the Kloe kit spiral staircase there is a steel base plate which sits on top of the lower floor. At the top there is a wooden landing plate which fits level with the upper floor. The height between those two points is known as the floor to floor height. Different buildings have different floor to floor heights and so the Kloe spiral staircase kit is adjustable so that it can fit the exact floor to floor height on your site.
What is the floor to floor height?
The floor to floor height should be measured vertically from the top of one floor to the next.
Floor to floor table
This table allows you to work out how many treads and risers you will need to be able to reach your floor to floor height. The term “riser” refers to the height of each step and the tread is the surface you stand on. There is always one more riser than there are treads because the last riser is the step up from the top tread to the landing plate.
| Floor to floor | No. of risers | No. of treads |
|---|---|---|
| 2100 - 2350mm | 10 | 9 |
| 2310 - 2580mm | 11 | 10 |
| 2530 - 2820mm | 12 | 11 |
| 2740 - 3060mm | 13 | 12 |
| 2960 - 3300mm | 14 | 13 |
| 3170 - 3530mm | 15 | 14 |
| 3380 - 3770mm | 16 | 15 |
Staircase Layout
Once you have determined the number of treads that will be in your staircase you also need to check whether or not the layout of the stair will be appropriate for your site. The drawings below show the typical layout of a 12 tread (13 riser) staircase. Of course your installation may well need more or fewer treads than this so if you want us to make a specific drawing for you please call our technical sales team on 0800 098 8778. Please bear in mind that the staircase must positioned so that it is at least 25mm clear of any surrounding walls.
Typical layout drawings - Clockwise rotation
Clockwise rotation refers to the direction in which that treads turn if you start from the bottom of the stair
Typical layout drawings - Anticlockwise rotation
Anticlockwise rotation refers to the direction in which that treads turn if you start from the bottom of the stair
The Landing Plate
The landing plate supplied with the Kloe kit spiral staircase can be used to fit round or square openings, or to fit against the side of mezzanines. As standard it has a triangular shape to suit a straight floor edge but since it is a wooden board you may cut it to suit a curved floor edge if you need to. Please note that finished openings/ stairwells must be at least 50mm bigger than the staircase diameter and ideally 100mm bigger.
As you might expect the Kloe kit spiral staircase needs to be securely fixed in a few key places. Before you buy a Kloe spiral staircase kit you need to take a close look at your site to see whether or not secure fixings can be achieved. The different types of fixing are:
Staircase plans and instructions
Here you can download drawings and installation instructions for the Kloe spiral staircase kit:
Base Plate
At the centre of the stair there is a galvanised steel tube attached to a steel base plate, which needs to be bolted to the lower floor. You need to make sure that when you erect the centre pole it is perfectly vertical. If the floor isn't level then put some packers underneath the base plate to compensate. Below are a few common types of floor and ways of fixing to them. Please bear in mind that if there is an under floor heating system present then you will need to be sure that the area is clear of pipes before you start drilling holes:
Concrete
Drill holes as required and bolt the fixing plate down with the standard expansion bolts supplied.
Concrete under insulation and screed
In this situation there is a danger that the weight of the stair could cause the insulation to compress and damage the screed and floor covering. One solution is to chemically fix threaded rods into the concrete slab and then fit some locking nuts so that the base plate is held just fractionally above the floor. You need to be sure that the threaded rods connect solidly onto the concrete and that you fill the shaft with the resin. The idea is that the load is imposed onto the concrete and not the insulation or screed.
Concrete floors under floating wooden floorboards
You can generally drill some clearance holes in the wooden floor board and then just fix into the concrete using expansion bolts. The only danger is whether or not your floorboards need space to expand and contract. If you are in doubt check with the flooring supplier. In most cases, and especially with laminates and engineered floor boards, they just tell you to leave some clearance around the holes in the wood.
Wooden joists
Replace the expansion bolts with some M10 coach screws and washers so that you can screw straight through the floor board and into the joists beneath. If there are no joists in the required spot lift the floor boards and put some in place.
Landing Plate Fixing Brackets
At the top of the stair there is a wooden landing plate which fits flush with the upper floor. It is bracketed on the underside to the apron of the upper floor. The brackets are typically fixed as follows:
Concrete
Drill clearance holes in the apron and then drill into the concrete and fix the brackets with the expansion bolts supplied. Screw the landing plate down onto the bracket so that the top of it is flush with the floor. Remember to drill a small pilot hole in the wood first to avoid splitting.
Wood
Replace the expansion bolts supplied with some M10 coach screws and washers. Screw the brackets in place and then put the landing on top and screw that down too. Remember to drill small pilot holes first to avoid splitting.
Baluster Fixing Cup
The first baluster is fixed to the floor to prevent the tread from bouncing when you walk on it (all the treads are connected together by balusters for the same reason). The way it does this is with the use of a special metal cup. The cup gets screwed to the floor first then the baluster sits in the cup and a grub screw holds it firmly in place. The exact type of fixing to the floor varies depending on the type of floor. Here are a few examples:
Concrete floor
Drill into the concrete or screed, fit the plastic plug supplied and then screw the cup to the floor.
Wooden floor
Screw the cup directly onto the floor (preferably over a joist). Remember to drill a pilot hold first to avoid splitting.
Wall Brackets
The Kloe kit spiral staircase can be freestanding. That is to say that it isn't essential for you to fix it to surrounding walls. However, if there is a wall very near to the staircase then you should bracket the stair to it to help reduce movement when you walk up and down. The positive effect of fitting wall brackets becomes more apparent with bigger staircases (i.e. lots of steps or a big diameter), where movement is most likely to occur. Brackets are most effective if evenly spread. Either find a spot approximately halfway up the stair, or two spots at a third and two thirds of the way up.
Solid walls
Find a position between two treads where the bracket can grasp the baluster and still reach the wall. Drill into the wall, fit the plastic plugs supplied and then screw on the bracket.
Stud walls
Prepare the wall to receive the bracket. Either fix a sheet of plywood under the plasterboard to allow fixings at any point or work out the exact position of the bracket and fit a vertical stud if possible or a horizontal noggin between to studs if not. The idea being that the bracket has something solid to fix to rather than just plasterboard. Then position the bracket so that it grasps a baluster between treads and screw it to the wall.

Frequently asked questions for the Kloe Spiral Stair by Arke
Can I specially order the Kloe Spiral Stair in any other colours or wood types?
Can I specially order the Kloe Spiral Stair in any other colours or wood types?
No. The Kloe spiral stair kit from Arke is only available in the standard colours. These are white, grey and black for the metal parts and a light or dark colour finish for the beech treads. If you are looking for alternative colours please email us at contact@staircasewarehouse.com with your requirements, and we will try to suggest an alternative product
Will my new staircase conform to the building regulations?
Staircase installations are subject to the building regulations. These are described in Approved Document K, and additionally for spiral stairs, BS5395: 1984: Part 2. It is important to understand that the regulations vary according to individual site circumstances and therefore you should check with the local authority that the installation you are planning is approved before purchasing a staircase. Staircase Warehouse is not responsible for ensuring the suitability of your installation for Building Regulations.
Should I specify the direction I want the stair to rotate when I order?
No. The Kloe can rotate in either the clockwise or anti clockwise direction. The direction is determined during the assembly.
How does the universal landing platform work?
The universal landing platform is wooden board that butts up against the side of the floor, level with the finished floor surface. It is supplied as an oversized triangle and is cut by the installer to suit site requirements. If the stair is being installed into a square opening the installer trims a straight edge and if the opening is circular he scribes and cuts a curved line.
The staircase doesn’t reach my floor height - can I extend it?
Yes. The modular design of the Kloe spiral stair kit allows you to extend the height by adding extra treads to the standard kit. You can also reduce the height by using fewer treads. Please see the assembled size table and stair plan drawing sections on the product information page for more information.
How long does it take to install the staircase?
If you have done your planning and preparation work beforehand, and your structural opening is formed the staircase should not take more than one day for two people to install fully.
Do I require any specialist tools?
The staircase has been designed to be installed by DIY’ers. No specialist tools are needed to install the Kloe spiral stair. The standard tools that you will require are as follows; electric drill/ driver, spirit level, Allen keys 2.5, 3, 4, 5, 12mm, plumb line, spanners, 13, 17, 30mm, measuring tape, hacksaw, Phillips screw driver, mallet and dill bits.
