Let your imagination take flight with a breath-taking addition to any property...
Kallisto design, manufacture and install luxurious, hand-crafted, structural bespoke precast concrete stair units. Our stairs are suitable to take a variety of applied finishes from timber to marble along with the addition of luxurious timber or steel balustrades and handrails, applied on site by others following installation. Please note, it is the requirement of the client to source all finishing aspects of the interior stair installation as this is not provided by Kallisto.
Utilising a range of industry-leading palletised adjustable moulds, we are capable of manufacturing flights of various curved geometries incorporating circular, elliptical and dogleg (winder), with or without straight treads. Generally, these staircase flights are manufactured as storey-height units with swept soffits in our offsite factory environment.
Our curved concrete stairs are manufactured either as a series of precast flights (each turning through a maximum of 270°) or as individual cantilever-style steps built into an adjacent wall. The helical/curved flights are cast inverted with a trowelled soffit and will need an applied plaster skim upon completion of installation.
Due to the constraints within our factory, Kallisto are unable to provide complete spiral staircases where the radius is greater than 270° winding around a central column. For more information on the types of staircase configurations we are able to manufacture and install, please visit the Stair Types & Definitions page.
