Original elements characteristic for staircases in buildings from this period were often stucco work, ceilings and walls framing, railings and doors woodcarving details, forged construction elements of stairs, floors and paneling - often made from precious materials. The composition of these elements accounted for a coherent look of staircases. Unfortunately, throughout the centuries and as a result of successive reconstructions - these spaces have lost their original character. At present about the nature of these interiors decides rather random fusion of all "modern" elements such as gas pipes and counters, internet cables, security doors and paneling oil on the walls.

Unfortunately, most changes made over the years is irreversible so as for this project we decided in advance to give up "conservation" approach – restore the original state – and instead to create a space that reconciles all the elements and at the same time will create a coherent interior space. As a rule we  assumed to hide all installations in cabinets (installation shafts) and use uniform gray colour for all elements of the staircase. The unified in this way space became a background for decorative mirrors which are treated as elements simultaneously historicizing and (in conjunction with flooding gray aura) creating a "virtual space" - unreal by affecting its "physicality" - changing relationships of ceiling, walls and floors and creation of surprising views and reflections.
