Hruškova 2, Cultural monument in Jižní Předměstí, Plzeň, Czech Republic

Hruškova 2 is a detached two-storey villa at the corner of Klatovská třída and Hruškova Street in Plzeň's Jižní Předměstí. Built in 1923 as a duplex for the Škoda pension institute, it has a U-shaped plan with the main entrance from the courtyard. In 1933 the west wing was converted into a single flat for Oskar and Jana Semler, with interiors designed by Adolf Loos and Heinrich Kulka.

The house was built in 1923 for the pension institute of the Škoda works. In the early 1930s the Jewish entrepreneur Oskar Semler, owner of a gramophone needle factory in Vochov, bought it to turn it into a family residence. In 1933 the basement, ground floor and first floor of the west wing were converted into one flat to a design by Heinrich Kulka, probably following a concept by his friend Adolf Loos, who could not finish the work because of illness and death. The Semlers emigrated after the Nazi occupation and the building was nationalised after February 1948.

The house is named after Oskar Semler, a Jewish entrepreneur who owned a gramophone needle factory in Vochov and bought the building in the early 1930s to turn it into a family residence. The preserved interiors of the Semler apartment now serve as a museum of period interior design.

The villa stands at the corner of Klatovská třída 110 and Hruškova 2, in Plzeň's Jižní Předměstí district, south of the centre. The main entrance faces the courtyard, not the street; the courtyard has a concrete surface and a stone-mosaic path. The two-car garage with a flat roof, built in 1939, is reached by a single-flight stair from the side of the building.

The interiors of the Semler apartment were preserved and now serve as a museum of period residential design. The house is listed in the Iconic Houses catalogue, which gathers 20th-century architecturally significant houses open to the public as house museums.
