Originally, the Art Nouveau house from 1908 carried the number 205. It was erected on the site of a small wooden house, which belonged to the families of Sablik and Honkisz in the 19th century. In 1880, the house was purchased by the merchant Tomasz Byrski who had it demolished to make room for a new one-storey brick house which was completed in 1895. The new owner had run a shop here from 1882, first under the auspices of the Agricultural Cooperative and later as his own establishment. The new shop was in competition with a nearby establishment run by the Jewish family of Gronner. In 1908, Tomasz Byrski carried out a major extension of the building which received a new floor and was transformed into the impressive townhouse that we know today. The date of the extension was placed in the steel weathervane on top of the decorative gable of the façade. Apart from the shop, Tomasz Byrski also ran a vodka, beer and wine bar, as well as a restaurant on the top floor which was open on Sundays and public holidays. According to Adolf Zuber, the owner would not allow excessive alcohol consumption in the tavern. Tomasz Byrski was a respectable citizen of Kozy. In 1913, he became the president of the local branch of the “Sokół” Gymnastic Society, whose members joined the ranks of Józef Piłsudski’s First Brigade of the Legions the following year. The Byrski family ran the shop and restaurant here until 1945. After World War II the shop was taken over by the communal cooperative “Samopomoc Chłopska”.
