Self-supporting balustrade staircase | Emporio Armani
2012, Vienna
It is an outstanding architectural masterpiece that enriches the luxury boutique in the heart of Vienna with sculptural elegance. The combination of box-type stringers and smooth underside cladding allows the self-supporting balustrade stringer staircase at Emporio Armani to merge into an artistic ensemble.


Prominent steel sculpture for luxury label
Armani's collection embodies stylish elegance and Italian craftsmanship in a unique way. The design and construction of the self-supporting balustrade stringer staircase echoes the luxurious ambience of the boutique in the Austrian capital and establishes a link to the classic prestige of the fashion brand with excellent craftsmanship and special design features.
The free ceiling openings of the self-supporting balustrade stringer staircase create an abundance of light and emphasise the excellent workmanship and technical perfection of the sculptural installation. A visible shadow gap at the transition between the balustrade stringers and the treads on both sides creates a visual contrast and separates the folded treads visually from the Marmorino levelling of the steel parts carried out on site.
Balustrade stringer staircase with homogeneous dynamism
From the ground floor, the self-supporting balustrade stringer staircase with its even curves and structurally supporting soffit cladding made of smooth sheet steel leads up to the 2nd floor of the boutique. Its parapet-high flat steel stringers continue as rounded ceiling railings at the two stair head landings and form the homogeneous overall dynamic of the self-supporting balustrade stringer staircase.
