He left behind a collection of buildings that together form a mosaic of styles, ranging from Neo-Renaissance, through Neo-Baroque, Neo-Rococo and Eclecticism, right up to Art Nouveau. Jan Tomasz Kudelski was an exceptionally talented architect who honed his professional skills mainly in Stanisławów and Lviv, and it was to these towns that he devoted his life.

Jan Tomasz Kudelski ( 1861–1937) was a Polish architect who was born in Budziska but studied in the capital of Galicia – first at grammar school, then at the local technical university. He took his first professional steps in Lviv, but after some time he moved to the aforementioned Stanisławów, and subsequently to Warsaw.

The young architect initially worked under the guidance of Julian Zachariewicz – a ‘virtuoso’ of Lviv architecture. He then began working with Jan Lewiński . During this time, he developed his skills as an architect, designing tenement houses and mansions in Lviv .

Together with Jan Lewiński, Jan Kudelski transformed the Siemieński family house into an elegant palace featuring Neo-Baroque reliefs. He also built the ‘Spokojna’ Villa for Franciszek Steifer, situated on Nabielaka (Kotlarewskiego) Street, as well as the Baczewski tenement house , inspired by Baroque architecture. Many of the buildings he designed still feature Neo-Renaissance or Art Nouveau façades to this day . Based on his plans, the Krzyżanowski Chapel was built at the Łyczakowski Cemetery, combining Neo-Romanesque and Neo-Gothic styles.

Towards the end of the 19th century, Kudelski was offered the post of site manager for the railway authority in Stanisławów . As it turned out, the architect fell in love with the city and spent almost three decades there, a period which marked the height of his creative output. Among other things, he designed a secondary school here , which was to be situated on Matejki Street, as well as the Main Post Office and the building of the ‘Sokół’ Society . Whilst in what is now Ivano-Frankivsk, he also designed the Austro-Hungarian Bank building, which is L-shaped and built in an eclectic style.
