The Diamond Tower (in Italian Torre Diamante or colloquially Diamantone) is an office high-rise building in Milan business district, on the corner between Viale Della Liberazione and Via Galilei.

[2] The Italian-American architect Lee Polisano, member of Kohn Pedersen Fox studio, designed the entire area master plan.

Polisano was supported by architect Paolo Caputo and by Jacobs Engineering Group Inc. for the architectural design while the structural plan was committed to Arup.

The Diamond Tower has in fact been awarded with the LEED GOLD certification, one of the highest ranking recognised by the Green Building Council.

After about 5 months, in November 2011, the external steel structure had reached the maximum height while the laying of the glass panels arrived at the eighth floor.
