This section contains our most common staircase construction methods and the styles that will suit.
A Closed Rise staircase is the standard construction for a timber staircase, by having the treads closed it allows the space beneath the staircase to be used for storage. This sort of construction is most commonly used by budget conscious builders and low-income clients.
An Open Rise staircase is defined as a staircase in which has the riser board is removed to create an opening through the staircase. These are most commonly used in a foyer as they allow the viewer to see straight through the staircase into the rest of the home.
A Closed string staircase is the most cost effective construction method, the treads and risers are grooved into the stringer and then glued & wedged to create a solid flight.

Cut String staircases are used when the client wants see the end-grain detail of the treads and/or risers. A Cut stringer is defined as a stringer, which is cut in a sawtooth fashion to allow the treads to overhang the stringer.

Mono-stringers stair designs tend to be one of the more expensive construction methods. As they are open in design. The stringer itself tends to be less apparent due to its located centrally and underneath the treads themselves. The ability of mono-stringer to promote a sense of lightness and openness is regarded as a desirable property. When compared to traditional closed or enclosed stairs, mono-stringers demand the use of relatively stronger materials in order to be structurally sound.
By using dual steel stringers, the staircase is allowed a sleeker look, because of the strength difference between Steel and Timber you can obtain a cleaner fixing. More often than not, this design is part of an open rise construction and is most suited to modern homes.
Curved Staircases are one of the most labour intensive build’s requiring a complete 1:1 replica of the clients wall to be constructed in our factory. The construction of a common curved staircase requires in excess of 25+ hours of labor.
The treads are the material on which you walk, at OzStair we offer 5 basic nosing profiles which can be used to change the style of your staircase to match the surroundings.
