Bosco Verticale is a groundbreaking residential complex in Milan's Porta Nuova district with two towers (111m and 76m), completed in 2014. Designed by Boeri Studio, the towers host over 800 trees, 4,500 shrubs, and 15,000 perennial plants from 90+ species on staggered balconies.
Developed by Hines Italia SGR, the project equates to 20,000–30,000 sqm of woodland on just 1,500 sqm of urban land. It produces oxygen, absorbs CO₂ and fine dust, reduces noise, mitigates heat islands, and boosts biodiversity. Agronomist Laura Gatti and structural engineers Arup ensured the system's viability.
Celebrated with the 2014 International Highrise Award and 2015 CTBUH best tall building, Bosco Verticale pioneered vertical greening and inspired global replications.
