[2] In 1909, his project for the Roman Catholic church in Zebegény, in 1909 the Óbuda Reformed parochial building, and in 1910 the Budapest Zoo complex (with Dezső Zrumeczky), were carried out.

[2] During the 1910s, he completed the Reformed Rooster Church in Kolozsvár (a city later known as Cluj or Cluj-Napoca) and the hospital in Sepsiszentgyörgy (Sfântu Gheorghe).

He lived off commissions and started a political career, choosing, unlike many in the Hungarian community, to accept the Romanian Kingdom's administration in the region as a given, while engaging in active opposition inside its legal framework (and authoring a manifesto calling on others to do the same).

From 1931, he was editor of the Erdélyi Helikon, and manager of the Miklós Barabás Guild (an independent interest group of Hungarian artists in Romania).

As a politician, he was the president of the Hungarian People's Union (Magyar Népi Szövetség, MNSz), and afterwards member of the Assembly of Deputies (1946–48).
