Creating Carsten Höller’s Oval Staircase at Palazzo Diedo, Venice

Costa Interiors played a crucial role in the creation of Carsten Höller’s staircase at Palazzo Diedo, handling the stonework, logistics, and installation. Learn more about this contribution to the world of luxury and bespoke interior design.
In June, Costa Interiors had the honor of contributing to an exceptionally important artistic project: the creation of the Venice Inclined Oval Staircase by German artist Carsten Höller, within the prestigious Palazzo Diedo in Venice, which was recently transformed into a museum thanks to the vision of Nicolas Berggruen.
Costa Interiors’ Contribution to Carsten Höller’s Staircase
The staircase, standing as a fusion of art and functionality, represents a modern reinterpretation of an unfinished 18th-century structure. Our contribution focused on crafting the stone sections, managing logistics, and ensuring timely installation, where precision and punctuality were paramount.

An Artwork That Merges History and Architectural Innovation
Working at Palazzo Diedo, a historic building transformed into a museum, required the highest level of expertise and care—qualities that Costa Interiors consistently delivers in bespoke interior design and the luxury sector. Our role in creating the elegant Vicenza marble and marmorino surfaces was indispensable in bringing to life a structure that not only connects the noble floors of the building but also invites visitors into a unique sensory experience, typical of Höller’s artistic style.
