Modern staircase designs tend to be simple and clean-cut. Sometimes this is created through the use of glass, metal or wrought iron integrated through the spindles or balustrade or with open risers or glass risers to amplify light and enhance the airy, fresh feel of the room. Other features can include extra thick strings or treads to add a chunky element to the design or solid wall balustrade for a sleek, clean, ultra-modern look. 

Floating Stairs

The treads on this type of stairs are cantilevered off a metal string hidden behind the wall plaster to create a floating staircase with minimalistic detail.

Centre Spine Stairs

Instead of the traditional two-string stair build, this staircase has a single string running up the centre of the stairs in either steel or wood.

In both of these stair designs the treads appear to be floating in mid-air. This effect has become very popular in recent years for those looking for something ultra-modern and very different.
