Historicistički ljetnikovac obitelji Grbac izgrađen je 1889./1890. godine prema projektu arhitekta Lea Hönigsberga u sklopu planiranoga cottage naselja na Josipovcu u Zagrebu. Usporedbom sačuvane arhivske dokumentacije i arhitektonske snimke postojećeg stanja utvrđene su pojedine etape povijesno-prostornog razvoja ljetnikovca. Svaka etapa prezentirana je grafičkom rekonstrukcijom trodimenzionalnog modela, a zaključci su verificirani nalazima konzervatorsko-restauratorskih istraživanja.The historicist cottage of the Grbac Family, built in 1889/1890 according to Leo Hönigsberg’s designs, formed part of a planned cottage estate in Josipovac in Zagreb.
