floating Stairs

A stair that contains a series of steps that appear to be supported at one end only.

Here is a sketch of a modern version of the old stone stair on the previous page. This type of stair and it's many offshoots are just about always internal.

• Many of the modern stairs like this have solid risers but when they don't they all have some sort of connection at the ends of the treads as detailed. It often takes the form of a cylinder or RHS with a bolt though both treads.
• Tying the back outer edge of a tread to the front of the one above has been a technique to stiffen open spiral steps for ages.
• From reading the previous page you will understand that this is essential.
• Also essential is a really stiff fixing to the wall which will resist the twisting forces to the treads.
• Each manufacturer seems to develop their own proprietary fittings for these stairs and there are many variations on the same theme.
