Casa Ghiringhelli, Rationalist residential building in Isola district, Milan, Italy.

Casa Ghiringhelli is an eight-story residential building in the Isola district with a black serpentine stone base contrasting against beige plastered surfaces on its dynamic facade. The structure holds twenty-four apartments distributed across seven floors with four commercial spaces at ground level.

The Ghiringhelli brothers, artists Gino and Livio, commissioned Pietro Lingeri in 1932; he had already fitted out their "Il Milione" gallery. Giuseppe Terragni collaborated on the design, presented to municipal offices in December 1933 and in final form the following month. Work ran from February 1934 to 1935. In 1949 the owners closed one of the two top-floor terraces to gain space.

The building shows modernist principles through its concrete structure and geometric patterns that represent Italian rationalist architecture of the 1930s. This design approach brought together function and form in a new way for residential living.

The building is located at Piazzale Lagosta 2 in the Isola district, easily accessible by public transport. The entire facade can be viewed from street level, with ground-floor windows offering good views of the interior spatial arrangement.

The plot had an irregular trapezoidal shape caused by two diverging streets. The architects solved this challenge with a complex system of setbacks and projections that mask the resulting asymmetry.
