Any staircase consisting of more than two steps must have a railing. Yes, even those beautiful floating stairs you saw in an interior design magazine, they too need a railing. If your proposed staircase is less than 1 m wide, you will need a railing on at least one side of the stairs, while wider staircases will require two.
For health and safety reasons, it is also essential that objects and limbs can’t get stuck in between the spindles of the railing. This means that a ball with a diameter of 100 mm must not be able to pass through the space between the spindles.
If your staircase has more than one landing, you will also be required to have gates at one or both sides of the stairs. As a safety precaution, those with young children should also consider installing gates at the top and bottom of a staircase.
