CityLife is a residential, commercial and business district situated a short distance from the old city centre of Milan, Italy; it has an area of 36.6 hectares (90 acres).

An international tender for the redevelopment of the old Fiera area, seeking to create an unprecedented level of connectivity with the surrounding urban context, concluded in 2004.

Painstaking efforts were made to protect and recover the area’s stock of trees, 120 of which were saved and relocated in the public parks across Milan.

CityLife has also reached a binding agreement with the financial institutions financing the project to redefine some terms and conditions of the original deal.

Further to the existing public transportation network, the CityLife area will be served by a new extension of the metro line 5, with a dedicated station at the centre of Piazza Tre Torri.

The Tre Torri offices have been awarded the GOLD level LEED™ pre-certification, but actual accreditation and post-occupancy performance is yet to be conducted and confirmed.

In the middle of a natural landscape, with pleasant rest areas, the courtyard is built on a circular hill that descends gradually towards the underground road.

The former Pavilion 3 of Fiera Milano City, which is located in Viale Cassiodoro with a total area of 15,500 m2 (167,000 sq ft), was reconstructed.

The Piazza Tre Torri, designed by One Works, is located in the centre of the three towers along the pedestrian pathway which links Largo Domodossola with the new public park.

The double storey plaza reveals itself at the two principal levels of the public domain, acting as a junction between the park and the pedestrian axis Domodossola.

Retail functions, strongly characterized in part by the fashion mall at the base of the Lo Storto, and the outdoor commercial activity distributed around the plaza and along the pathway towards Piazza VI Febbraio, allow the public square to open itself up to the city and the surrounding park.

The strong spatial articulation is resolved through large openings that overlook the underground plaza, freeing the view of the three towers from below and allowing for direct integration with the same.

The shrubbery and ornamental grasses, which ornate the flowerbeds in front of the towers, help to confer a certain intimacy to the private outdoor areas.

In this specific case, the electrical cables use the canopy's structural supports as their starting point and run in an appropriate manner throughout the open space illuminating both levels at the same time.

The international competition for the design of the park was launched in 2010 and was won by the architectural studios Gustafson Porter, Melk, One Works and Ove Arup.

The landscaping design reflects the diversity of the Lombard environment, recreating the differences in height between the mountains and the plain, the two most distinguishing features of the region.

The south entrance to the new park will be the historic Fountain of the Four Seasons (Fontana delle quattro stagioni) in Piazza Giulio Cesare, restored to its splendour and to working order.
