Stairwells and lift shafts 

They have the size and repetition necessary to be designed and realised in 3D elements, although they can also be realised using 2D panels.

The wells and shafts are connected to the building structure between floors in such a way that they provide the necessary bracing and horizontal mechanical rigidity to withstand the horizontal forces to which the building is subjected.

The stairs and landings are also prefabricated.

This 3D shaft/stairwell system is suitable for any type of high-rise building structure (on-site / prefabricated / metal / timber).
