Orti Antichi Residential development, Milan

"Orti Antichi" is a luxury residential complex in the centre of Milano, surrounded by streets B.D'Este, B.di Savoia, Mondadori square, San Martino and Santa Lucia.

The project involved the refurbishment of the existing 10 buildings, partially demolished and partially structurally transformed, internal facades completely re-built with the addition of balconies, but keeping the historical facades on the streets. An underground parking under the garden and the new buildings, plus a gym, lobby and community spaces, complete the program.

The complex is composed by different buildings:

-Building A: residential, located inside the perimeter, rebuilt after demolishing of the existing one;

-Buildings B and  C: office space at ground floor and residential use from first floor up, completely refurbished and structurally modified;

-Building  D: residential, completely refurbished  and structurally modified, relocation of the entire staircase blocks from outer to inner façade;

-Building  E : community use office space at ground floor and main lobby; rebuilt after demolition  but saving the historical façade on the outside;

-Building  F : residential, completely refurbished and structurally modified;

-Building G : residential, located inside the perimeter, rebuilt after demolishing of the existing one;

-Building  H :  residential, completely refurbished  and structurally modified, relocation of the entire staircase blocks from outer to inner  façade;

-Building  I : residential, completely refurbished and structurally modified;

-Building L : residential, located inside the perimeter, rebuilt after demolishing of the existing one;

-Two-level underground parking built under the courtyard and new buildings;

-Technical spaces at basement -3 under a part of the parking.
 

The underground parking has been excavated inside the perimeter of the outer buildings, by using concrete diaphragm walls and locally micropiles. All underground  perimeter has been completed by an internal concrete wall  and membrane to ensure water tightness. A bottom slab is cast over bentonite membrane for the same reason.

New buildings are based on concrete frames and traditional hollow-brick and concrete floors. Structures for upper  floors of new buildings (attics) and roof structures for all buildings are made of steel/composite.

Structural refurbishments, transformations and strengthening of the existing buildings have been implemented by using different systems and tools:

carbon fibre reinforcing for floors, beams, columns;

rebuilding of entire floors in composite steel-concrete structures or traditional hollow-brick and concrete;

strengthening of bearing walls by spray-concreting and mesh reinforcement, and/or by inserting metal columns.
