In addition to the two Prague architects, local artists from the Glass school also participated in the construction of this new building. They were also members of the museum's association. The first plans for a new museum building were made in 1924. After a few years, the plans for this building were drawn in 1931 and realised from 1934 to 1936. On this website are some pictures, also showing the original plans. They show, that the house was designed with two storeys in 1934. It was decided in 1935, as construction works were already in progress, to built one more storey.
Nowadays the museum has a slightly larger exhibition area than originally. The building is listed since 2018.
A similar multifunctional building used by a bank and the city museum was also built in Bautzen, Germany a few years earlier.
