Antonio Citterio Patricia Viel architecture and design firm completed the regeneration of two historical buildings in the heart of Milan, Italy, into a flexible and sustainable complex, offering a glimpse of the working space of tomorrow.

San Babila Business Center

International architecture and design firm Antonio Citterio Patricia Viel (ACPV) unveiled the renovation of San Babila Business Center, of Galleria San Carlo, and of Galleria Passerella 2, in the heart of Milan’s historic center. Transforming a 21,000 GLA (Gross Leasab le Area) block of buildings designed in the Fifties into a flexible and sustainable space, ACPV’s intervention took a careful approach to the conservation of the buildings’ original details, while elevating their character and elegantly integrating the architecture in the surrounding urban context.

By meeting the highest international building standards for environmental sustainability and personal well-being, the project by ACPV created a flexible space able to adapt to its users’ needs, while preserving the original architectures as designed in the Fifties by renowned architects, Gio Ponti, Fornaroli and Soncini brothers.


The mixed-use building block (office and retail) has an E-shaped layout and comprises seven floors above ground and five basement floors hosting storage, plant rooms and parking spaces.

Overlooking Corso Vittorio Emanuele II and Corso Europa, the two main wings of the building benefit from outstanding visibility. The offices, with cutting-edge design and abundant natural light, feature flexible, functional, and stylish spaces. The rooftop of the block on Corso Vittorio Emanuele hosts a 320 sqm terrace with a stunning view over the Duomo cathedral and the city’s skyline.

 “Our design responds to a dual purpose: the creation of a particular design language for a single yet extensive office complex, while undertaking an urban regeneration intervention right in the heart of the city’s busiest, best-known cultural, commercial and tourist destination,” said Antonio Citterio, co-founder of ACPV firm, “We redesigned the buildings’ façades, entrances and lobbies – opening them to the city.”

We wanted to infuse new life to the buildings, enhancing the original architecture of renowned architects such as Gio Ponti”, said Marco Brambilla, partner and project director at ACPV. “We had the marbles and original details renewed and we designed the new addictions with new lighting items in order to highlight the historical threshold difference for some elements of the shared spaces – such as the elevators – to make them more accessible and prominent.”

The redesign of the 21,000 GLA block of buildings also involved connecting the layout of Galleria San Carlo and Galleria Passerella 2, creating a continuous space able to allocate up to six tenants each floors .

Patricia Viel, co-founder of ACPV firm:

The new space design offers a glimpse of the workspace of the future,”

says. “The space of the offices can be easily changed and adapted to their users’ needs – a feature that comes quite handy, considering how work paradigms are changing because of the covid-19 emergency.”
