Oskar Semler's family first lived on Jagellonská Street (near today's Klatovská Street). It was from this residence that they originally planned to move to a family home at 19 Klatovská Street, which would also include space for their company headquarters. This move, however, meant the home needed to undergo significant renovations and an addition of two extra floors. With these complications in mind, Oskar Semler eventually came to an alternative solution, i.e. he decided to buy an apartment building at 110 Klatovská Street. In 1932, he asked Adolf Loos to create a project for the generous adaptation of the apartment, which would encompass one entire wing of the home. However, due to Loos’ failing health and subsequent death, the completion of his design and renovation ideas were taken over by his disciple and collaborating architect, Heinrich Kulka. Oskar Semler moved with his family to their new home in 1934.

 

This is the only apartment in Pilsen where Loos implemented his unique principle of Raumplan - the individual rooms in the apartment differ in their height, having been elevated to several different levels and interconnected by stairs to create continuously adjoined spaces. In the apartment, we can admire the Raumplan principle via the spacious lounge with its cladding of Finnish birch, the flooring made of rare Makassar, and the fireplace of clinkstone blocks. There is also a bookcase, red-painted ceiling beams, and gilded planks. A number of details have survived to this day, including the dumbwaiter which was used for transporting food from the kitchen to the individual rooms at their varied height levels. The apartment is divided into two sections: the first is accessible to visitors, and the second remains a carefully separated private area, containing the bedrooms and children's rooms on the upper floor of the house.

 

The house was transferred from the property of the city of Pilsen to the property of the Pilsen Region, and it is currently under the administeration of the Gallery of West Bohemia. The Gallery intends to establish a Research Centre of Architecture on the premises once the apartment’s renovations are complete. The first section of Oskar Semler's apartment was opened to visitors in November 2015. Nowadays, the guided tour remains temporarily closed due to the reconstruction of the home.
