The Del Grosso team has completed a new job with Unopark by Bauwerk 12.5x70x490 (with no less than 5.5mm of noble) and Casapark planks in the construction of the staircase, a complex job but at the same time easy to implement thanks to the precision of Swiss floors, yes it is a first choice varnished European oak, the staircase was entirely made with a jamb with precise cuts in the edges.
