Through its diverse culture, creativity and solidarity with the environment, ARIA immerses its citizens in a variety of lifestyles that boasts workplaces, sites for the production and use of services: sustainable living based on inclusive and innovative experiences of cohabitation and collaborative temporary uses.

Thanks to the new IED international campus, the POD science district is dedicated to the dissemination of future eco-friendly technologies, and the intelligent management of open spaces. The renovation of the historic buildings preserves the cultural and historical heritage and goes well beyond the requirements of the Sovrintendenza. Not only this, but the development of Aria helps to promote a more circular built environment and economy.

Aria is a new neighborhood, alive, full of activities and exploring new ways of learning, having fun, growing up, living, and working. It will be one of the biggest affordable housing interventions of the new millennium. The project will be the first Carbon Negative Area in Milan thanks to the Ectogrid energy district and the  photovoltaic energy of the Renewable Energy Communities. Aria will certify the buildings as LEED Gold, and the masterplan as LEED for Cities & Communities. 

The role of plants will reduce environmental impacts thanks to parks, green yards, vegetable gardens, facades and thanks to the Air Factory, will purify indoor environments, filtering atmospheric contaminants.

Presentation of the site

The Ex Macello site is a disused area spanning around 15 hectares, the site of the communal slaughter house and of the poultry and rabbit market in the real estate compendium of the Milan wholesale market. Situated in the south-east district  of the city, in the district of Calvairate in Municipality 4, the area is a stone’s throw away from the Milan Porta Vittoria station, which is served by the suburban lines that link the metropolitan area to the city centre through the railway link. This enables the business centre of Porta Nuova and Repubblica to be reached in a few minutes, as with the Rogoredo station, which is served by high-speed trains, and the Forlanini station, linked to Linate airport by the M4. The Milan 2030 Plan identifies one of the “Piani Attuativi Obbligatori” (obligatory implementation plans) on site, one of the areas in which is provided a specific town planning regulation aimed at managing the regeneration of the areas. It provides a mix of urban functions including social housing at accessible prices.
