Galvanised metal frame mezzanine to be used for storage, inserted within an existing warehouse containing industrial refrigeration and air conditioning machinery. The structure is anchored to the existing one with floor beams to form the mezzanine floor and the addition of four new columns in Hea 240. On the sides facing the void, on the other hand, railings were built from scratch, as well as a single-ramp metal staircase that allows access to the structure.
