The round glass elevator represents the spatial ambition of the staircase taken into a new dimension: a panoramic vertical vehicle that offers 360° visibility as it rises, transforming mobility between floors into a spatial experience. Siller Treppen's cylindrical glass lift systems are designed to complement the manufacturer's bespoke staircase range — conceived as architectural objects that hold their own in any interior rather than functional insertions that compromise the design around them.
Siller's round glass elevator systems are shaft-free in the conventional sense: they use a self-supporting glass cylinder as both the structural enclosure and the aesthetic element, requiring no masonry or concrete shaft and therefore a significantly reduced structural intervention in the building. The drive mechanism — typically a hydraulic or traction system — is compact and quiet, and the cabin interior is finished to the same standard as a bespoke piece of interior design, with options for timber panelling, stone flooring, and custom lighting. Diameter and cabin dimensions are configurable to suit the floor plan and the number of levels served.
Round glass elevators from Siller are specified for luxury private residences where accessibility is required alongside an uncompromised aesthetic, for renovation projects where a lift must be inserted into an existing building without major structural works, and for any project where the client's brief demands that every element of the interior — including the vertical circulation — should be a designed object rather than a utility. They are frequently installed alongside or within Siller's helical or glass staircase systems, forming a complete vertical circulation composition.
