Torre Solaria, Modern residential skyscraper in Garibaldi district, Milan, Italy.

Torre Solaria is a 143-metre residential skyscraper at the corner of Via Melchiorre Gioia and Viale della Liberazione, above Piazza Alvar Aalto. It has three wings of different heights converging on a central core that brings in daylight, and 102 apartments including duplexes and triplexes. The photograph shows a slender dark glass-and-metal tower with pale curved balconies stacked in a regular vertical rhythm on the front face.

Construction began in January 2010 with foundation excavation, and the tower topped out on 22 October 2012 at 143 metres. It was built as part of the Porta Nuova project on the site of the former Milano Porta Nuova station, alongside the Aria and Solea towers. The property passed to the Qatar sovereign fund in 2015.

The tower's name comes from the three wings that converge on a central core, a layout designed so each of the 102 apartments, including duplexes and triplexes, receives maximum natural light. The terraces were conceived as an extension of the interiors, with irregular placement and etched-glass parapets of progressive transparency. Wind-tunnel tests on a scale model shaped the parapets to keep the terraces comfortable.

The tower rises at the corner of Via Melchiorre Gioia and Viale della Liberazione, above Piazza Alvar Aalto, beside Torre Aria and Torre Solea. The surrounding area is pedestrian, so the three towers are seen on foot from the square. Metro and rail stations Repubblica and Garibaldi, plus the Gioia stop, are within walking distance.

The tower's three wings rise to different heights around a central core that draws in daylight, and the 102 flats include duplexes and triplexes. Wind-tunnel tests on a scale model shaped the etched-glass balcony parapets, whose transparency increases gradually to limit turbulence on the terraces.
