The former ATM bus depot stands at the corner of Viale Zara and Viale Stelvio in Milan’s Isola district. The site is being offered for sale for residential redevelopment; ATM, Milan’s public transport operator, is the property’s owner and seller, but the developer has not been identified in the available reporting. 312
ATM’s sale conditions require at least half of the project’s gross floor area—no less than 8,750 square metres—to be used for social housing, with at least 150 homes envisaged. These dwellings are intended primarily for ATM employees who cannot afford market rents in the Milan metropolitan area. Under the proposed arrangement, the homes would be rented to Fondazione ATM, which would manage their allocation and leasing. The remaining floor area may be developed as market-rate housing. 512
The complex occupies a site of about 17,000 square metres, according to ATM’s 2025 account of the housing initiative. 11 The depot was built between 1937 and 1942 in the Rationalist style, based on work by ATM’s technical offices, with engineer Giuseppe Casalis responsible for the structural work; the corner building and some other parts were restored in 2018. 2
By June 2025, interior remediation work had been underway for about a month. 2 The cited reporting does not name a selected developer or architectural designer; an August 2026 Urbanfile update said it was still unknown who would carry out the conversion. 3 The redevelopment initiative dates to 2025, while the depot itself dates to 1937–1942; no separate project founding date is stated in these sources. 25
