For this prestigious Johannesburg private residence we have been commissioned to produce and lay the large and impressive staircase that goes up with a white marble structure and an iron railing with brass decorations. The design of the staircase, signed by the architect Giulia kjslsA, expresses the total monumentality of the building. The parapet is inspired by the impero style and its brass decorations were mechanically mounted through the use of specific assembling machines to guarantee the durability of the application.
