This exclusive spiral staircase built by the Brass Workshop for a private suburban home near Moscow presented an exceptional engineering challenge.
The task set before the crack team of architects led by head architect Dmitry Kiryazov was to design a staircase that would look grand, elegant and ethereal all at the same time. The use of brass in the banister and string, set against the marble stairs, takes care of the luxury look while the light, ethereal quality is provided by the glass tubes in the banister. Moreover, the brass parts cast multiple reflections on the glass, intensifying the impression of luxury. The handrail of man-made stone serves to further enhance the palatial look.
The Brass Workshop designed a metal staircase frame with two strings and strengthened stairs.
The staircase string was roll-milled to a preset radius. The stairs were carved with a laser. The staircase assembly was tested on a purpose-built bench in the factory shop. Before installation at the site, the metal frame assembly had to be cut up in order to build around a doorway with a glass portal that was in the house.
The metal frame parts were delivered to the customer’s property and manually carried inside.
The metal frame was welded back together in its intended place.
The facing of the staircase string was supposed to repeat, in brass, the polished ornament of the banister. As the customer would not allow any visible joints or gaps between the brass parts, the Brass Workshop team used a coat of liquid metal – in this case, brass – on the radial sections of the string.
The banister was assembled section by section in the shop. Then it was delivered piecemeal to the property and assembled from the top down.
This spiral staircase contains more than 5,000 brass parts, milled and lathed to perfection.
The surfaces of the brass parts of the staircase are polished, patinated, and covered with conservation wax. The sheer glass tubes are polished.
Extra buttresses, replicating the shape of the banister, were deployed to enhance the banister’s constructional strength. The buttresses were positioned at an interval of 1.5 to 2 meters, and handrails were placed on top.
We wish the owners of this residence health and longevity, and we hope they are as proud of their brass and glass staircase as we are!
