One of his poems was published in 'Gazeta Polska' in 1929 under a pseudonym. He officially debuted in 1936. Buczkowski ran an amateur theatre, for which he wrote "Zabójstwo", a play. His first novel, "Wertepy", was seized by the police because of its harsh portrayal of life in poverty-stricken Volhynia (now part of Ukraine). Buczkowski wrote his second novel, "Black Torrent" in 1946. In 1953, he began to paint more frequently and display his works in Warsaw. Works such as "Black Torrent" ("Czarny potok"), "Dorycki krużganek", "Młody poeta w zamku" and "Pierwsza świetność" all reference the terror of the Nazi occupation of Poland and World War II. Buczkowski's prose is characterised as experimental and original for its disregard of the traditional rules of storytelling and dialogue. The author considered "Kąpiele w Lucca", a novel published in 1974, as his greatest work and regarded some of his later works as its supplements.
