Stjepan Planić, also a member of group "Earth", with his numerous buildings made a makeover of Zagreb and earned a place in the "Anthology of Modern Architecture". Every project of his is marked with some new idea: "Villa in Kozarčeva street" from 1931 is gradually accommodated to the hillside, ""Tomislav Home"" in Sljeme from 1935, made out of wood and stone, has a unique plane in the shape of letter Y, while circular "villa on the Prekrižje", also from 1935, has radial inner walls. He fought for the architectural freedom to plan the buildings accordingly with climatic conditions, the sun, the wind and the sightings, and for the affirmation of new social and human ideas in habitat culture.
