Casa Baslini, Palace and national heritage site in Milan, Italy.

Casa Sola-Busca, known in Milanese dialect as Ca' dell'orègia (house of the ear), is a triangular-block palazzo at Via Serbelloni 10 and 12, built 1924–1927 to Aldo Andreani's design. The main entrance carries monumental tympana, volutes and decorated balconies; the ground floor has rusticated stonework and windows with heavy grilles, while upper floors away from the entrance have plain rectilinear mouldings.

The palace was built in the early twentieth century under architect Aldo Andreani's direction as an example of modern Milan architecture of that era. The structure marks a turning point as Milan evolved from the late nineteenth century toward new architectural approaches.

Milanese call the building Ca' dell'orègia, house of the ear, after the ear-shaped intercom at the secondary entrance on Via Serbelloni 10. The bronze piece, titled "L'orecchio del portinaio" and signed Andreani, is often wrongly credited to sculptor Adolfo Wildt, who taught Andreani at the Brera Academy.

The building sits in a central neighborhood of Milan and is within walking distance of several other architectural landmarks. Via Gabrio Serbelloni is close to major public transportation, making a visit straightforward.

The building kept its original exterior while adapting its interior to serve modern uses over the decades. This dual nature makes it an interesting example of balancing preservation with change in Milan's architecture.
