This adaptive reuse project addresses the diverse needs of a rapidly growing and densifying Buenos Aires, while prioritizing the 2030 sustainability goals that have been set by the city. The city plans to plant 100,000 trees by 2030 but space is limited in the streets, so why not grow 100 of them on this site that’s been sitting empty for 8 years? In the city center sits an abandoned 500,000 square foot building where the existing structure can be eroded to form a lush public park that cools down the neighborhood while simultaneously shading a new office tower that slots in behind it. The dense mixed-use program would also include short-term conventillo style corporate housing, publicly accessible event space, a transit connection, light retail and a museum. The project has 2 main intentions: first, to develop a program that attracts locals and tourists alike and, second, to create a sustainable landmark that celebrates the city’s 2030 goals, making it a happier and healthier city for all.
