Designer stairs at Seehotel Riva

Premium-class staircase architecture that impresses with its sophisticated design alone. With an interplay of geometry, material and light, these self-supporting stairs impress above all with the harmony of steel and wood.

Extravagant staircase architecture

At the Seehotel Riva in Constance, these extravagant staircases boast an exclusive design. Premium-class staircase architecture that impresses with its sophisticated design alone. The technical and design challenge has been excellently implemented: elliptically curved flat steel balustrade stringers with a white lacquered surface create a harmonious contrast to the elegant wooden covering of the folded steps. Another highlight is the steel soffit lining of the spiral stairs, which is curved to follow the course of the stairs. With an interplay of geometry, material and light, these self-supporting stairs impress above all with the harmony of steel and wood.
