Cut staircases often have a stringer that has been laid in a ‘zig zag’ pattern with the treads exposed at either end (they usually overhang the stringer). The balustrade sits on top of the treads rather than the stringer, which results in a more open stairwell.
The layout of cut stairs actually means that the balustrade becomes more of a standout feature. This is the perfect opportunity to choose a more decorative balustrading that the eye will really be drawn to, such as an intricate wrought iron pattern.
The nosing also becomes a hero of the design; as the treads generally overhang the stringer, your chosen edge (pencil round, square or no overhang) will be quite defined and visible.
