Back in history the Praguers had to wait a little longer for this building. Although the competition was held in 1926 and construction was due to begin in 1927, the project did not start until 1929 and construction then took almost five years. The building was symbolically opened on 7 March 1935 on the occasion of the 85th birthday of Czechoslovak President Tomáš G. Masaryk. The fact that the building was given a prominent role was due to the issue of electricity. Although this medium was not new, it began to influence people's everyday lives more and more in the 1930s.
It is interesting to note that the consortium of electric companies included the Prague transport companies. Customers bought their season tickets on the ground floor. However, the company also offered a second area. This included the municipal utilities, which provided the electricity. They promoted also all kinds of electrical devices. This meant that electrical household appliances were presented and sold in the building's ground floor. The concept of electricity was widely disseminated to the population.
During World War II, the light-coloured facade was painted dark to protect the building from air raids at night. Unfortunately, it was never possible to completely remove the dark colour afterwards. The spirit used to wash off the colour also damaged the glaze of the ceramic cladding. After the end of the war, only the transport companies remained in the building. They used it until the 1990s. After that, the building became abandoned. It wasn't until 2018 that the renovation breathed new life into it, used as an office building today. For the Open House festival this great building is largely open to the public one weekend a year.
