Allianz Tower

Allianz Tower, known as Il Dritto (The Straight One), was designed by Arata Isozaki & Associates and Andrea Maffei Architects. At 207 meters, it is one of the tallest skyscrapers in Italy and serves as the new Allianz headquarters, accommodating 50 floors of office space.

The tower is defined by an ultra-thin, modular profile composed of eight vertical modules, each comprising six floors. This vertical articulation emphasizes slenderness while supporting the structural and functional requirements of a high-rise office tower.

The façade is a high-performance, fully glazed curtain wall with triple-glass units, subtly curved outwards. The cold-bent exterior panels and straight interior surfaces are engineered to maintain transparency, optimize daylight, and enhance visual continuity across elevations.

The vertical sequence of rounded forms generates a subtle sense of vibration in the volume, while fully glazed short elevations reveal the mechanical series of six panoramic lifts. The architectural concept of an “endless tower” is reinforced by the slender geometry and continuous façades.

Structural resilience was a central consideration. To withstand seismic events without reducing office space at the top, four gold-painted external steel buttresses were introduced, anchored into the structure at the 11th floor, combining engineering efficiency with architectural expression.

The project demonstrates how advanced façade systems, modular high-rise design, and integrated structural solutions can be combined to achieve both aesthetic refinement and high-performance functionality in contemporary office towers.
