Bosco Verticale (Vertical Forest) is a pair of residential towers in the Porta Nuova district of Milan, Italy, between Via Gaetano de Castillia and Via Federico Confalonieri near Milano Porta Garibaldi railway station. They have a height of 111 meters (364 ft) and 76 meters (249 ft) and contain more than 900 trees (approximately 550 and 350 in the first and second towers, respectively) on 8,900 square meters (96,000 sq ft) of terraces. Within the complex is an 11-storey office building; its facade does not include plants.
The towers were designed by Boeri Studio Stefano Boeri, Gianandrea Barreca, and Giovanni La Varra. It also involved input from horticulturalists and botanists. The building was inaugurated in October 2014.

The project was designed as part of the rehabilitation of the historic district of Milan between Via De Castillia and Confalonieri in Porta Nuova, which is known to be the richest business district in Europe. Bosco Verticale is one of the biggest European redevelopment projects, consisting of two residential towers of which the largest is 26 floors and 110 meters high (called Torre E) and the smaller tower is 18 floors and 76 meters high(called Torre D). It contains 400 condominium units priced from 3,000–12,000 Euro per square meter.
The building itself is self-sufficient by using renewable energy from solar panels and filtered wastewater to sustain the buildings’ plant life. These green technology systems reduce the overall waste and carbon footprint of the towers. Lead designer Stefano Boeri stated, “It’s very important to completely change how these new cities are developing. Urban forestation is one of the biggest issues for me in that context. That means parks, it means gardens, but it also means having buildings with trees.”
The construction of the towers began in late 2009 and early 2010, involving 6,000 onsite construction workers. Between mid-2010 and early 2011 construction progressed very slowly and the towers rose by only five floors while the core rose to the seventh floor. Construction progressed throughout 2011, and by the beginning of 2012 the structures were completed, and construction of the facades and installation of the plants began on June 13, 2012. The building was inaugurated in October 2014.
On 19 November 2014, Bosco Verticale won the International Highrise Award, a prestigious international competition held every two years to honor excellence in recently constructed buildings that stand a minimum of 100 meters (328 feet) tall. The five finalists were selected from 26 nominees in 17 countries.
On 12 November 2015, the Council on Tall Buildings and Urban Habitat (CTBUH) Awards Jury selected Bosco Verticale as the overall “2015 Best Tall Building Worldwide” at the 14th Annual CTBUH International Best Tall Building Awards Symposium, Ceremony & Dinner, celebrated at the Illinois Institute of Technology, Chicago.
