Kaspar Julian Draniewicz (1867–1939) was a Lviv-based builder, architect, and entrepreneur active at the turn of the 19th and 20th centuries. He was born in Lviv into a family with artisan roots. He received his education at the Construction Department of the Imperial-Royal Industrial School in Lviv, where he studied from 1891 to 1895. At the same time, starting in 1885, he gained practical experience working with prominent construction firms in Lviv, which gave him a solid technical foundation.
In 1895, after completing his studies, he passed the state certification exam at the Governor’s Office in Lviv, receiving the title of certified master builder, which entitled him to supervise construction and run his own practice. He primarily worked in Lviv, where he designed and built numerous rental houses in the styles of historicism and, later, early Secession. Some of his buildings are notable for their rich decorative plastic work, executed by the sculptor Józef Szebest. From 1912 to 1916, he ran a workshop together with architect Edmund Pliszewski, specializing in the production of architectural ornaments and decorative facade elements, particularly in the Art Nouveau (Secession) style.
Draniewicz was also actively involved in professional associations. He was a member of the Lviv Society of Industrial Carpenters, Bricklayers, and Stonemasons, serving on its board — a reflection of his high standing in the professional community. A number of early 20th-century residential buildings bear his signature, characterized by careful facade design and consistent construction quality.
He died in 1939, leaving a significant mark on the architectural landscape of interwar Lviv.
