Staircase

A distinctive feature of this staircase is its continuous slide at the lower part, elegantly reconnecting the two lateral structures. The entire structure is unified into a monolithic block, skillfully concealing any visible fastenings or joints. The glossy red resin, applied on-site by a specialized artisan, further enhances the staircase’s
aesthetic appeal.
Versatility is a key aspect of this design, as the structure can be tailored to various preferences. Options include polished or satin stainless steel, gold-plating, or a coating of oxidized bronze. The steps offer a choice between different wood essences like beech, oak, walnut, or teak.
