Glasstree Staircases

Glasstree is a system composed by supporting elements of the steps which recall the branches of a tree. For the version Glasstree Spiral this celebration of the nature is extended so to make the entire structure look “natural”. Sober but highly functional lines ensure this model a stage presence of strong impact in all environments, meant to last over time.

Backbone Staircases

Backbone is developed by using a same basic module and it enables the construction of linear and bent structures. This system is to be considered for its flexibility granted by its capacity to rotate along the vertical element of the basic module and by the possibility of using rings which adjust the treat of the step, besides of many other types of accessories which grant the possibility to work with floor and wall supports or through structure tighteners.

Glasstep Staircases

Glasstep is a system worked out to build allglass stairs thanks to the use of stainless steel elements for the connection of the different glass components. This kind of minimal design stairway can be adapted completely to any type of environment, being it either classic or modern.



Innovation is the result of the present catalogue: offering nearly unlimited possibilities to create customized stairways but with the advantage of a modular system. No need of welding, of needing to study how to make stable a product, besides the possibility to develop from time to time customized solutions that can be changed at any time.


Modularity has been a great challenge for us: to create modular elements able to adapt themselves to various requirements and situations in order to build modular and easy to be assembled stairways. The result has been achieved thanks to the planning of a basic module compatible with floor and wall supports, such as those necessary to tighten the structure, through stainless steel ropes, or those for the adjustment of the step height.


The lightness of these structures is the result of an accurate study of the stainless steel performances and physical specifications. By working with flat metals and structures with inverted arch having the same structural capacity of the glass we have been able to achieve a technical and aesthetical result which sets off this concept.



Roberto Santi was born in Caracas , Venezuela , in 1979. In 2005 he graduated from the Academy of Architecture in Mendrisio, Switzerland after taking part in the ERASMUS project at the ETSAB Barcelona in 2002/2003. Hi decides to make his professional training abroad working at the renowned Architectural Firm Jung Brannen in Boston, United States and in Spain at the Architectural Firm Ramon Sanabria in Barcelona and at Duch / Pizá , Setdisseny and 3i Arquitectes Firms in Palma de Mallorca. In 2010 he decided to return to Italy and found, with Claudia Bacci Garriga Architect, the Architectural & Design Firm Basarchitetti in Bassano del Grappa. Inside the studio they develop architecture, interior design and industrial design projects in collaboration with the major companies in the area.


Matteo Nabissi was born in Schio (VI), Italy , in 1981. He studied architecture at the Venice Architecture University IUAV and at the Architecture School at ENSA - V in Paris. During his training develops a research on the theme of urban design and construction of complex future sustainable scenarios in large metropolitan areas, investigating the relationship between landscape networks and living. He takes part at Vitra + G. Pompidou Centre workshops in Paris. In 2010 he joined the Fabbrica Saccardo Architectural Firm, developing architectural and design projects. In 2013 he is the tutor of the SchioDesignOpen a urban laboratory promoted by the City of Schio with the purpose to investigate creative attitudes and new forms of contemporary city living.
